0.30 ml enanthate E3D put me at 742 trough free T PMOL, Total T 30nmol and shbg 8 (single digit shbg always)
I felt really good on this dose but then i lowered to 0.20 E3D, and i started getting a bit of brain fog, less drive and motivation. My urologicst doesen’t keep people over the reference range, and to me it sounds crazy aswell that i would need to be that high in order for symptoms to relieve, is it pointless to look at the T level and just go based on how i feel and how my bloods look? my HKR went up 1% in 5 months with this dose, everything els got better (Lipids, liver) but more likely to do with diet.
I waited 10 weeks and still didnt feel as good as i did on the higher dose.
are these high levels/slighty over reference range safe long-term if Bloods and BP stay good?

The standard starting dose across the board by those in the know is 100 mg T/week or better yet 50 mg T every 3.5 days.

140 mg T is too high a dose off the hop.

There will always be time to titrate the dose if need be.

Start low and go slow,

Keep in mind that although TT is important to know FT is what truly matters as it is the active unbound fraction of T responsible for the positive effects.

You stated that you felt great overall on your previous dose injecting 60 mg T every 3 days which had you hitting a high-end trough TT 865.3 ng/dL and more importantly a high-end trough FT 742 pmol/L or 21.4 ng/dL.

Not sure what testing method was used for FT but chances are it was tested using the known to be inaccurate direct IA (CLIA/RIA) or calculated using a modified Vermeulen as your trough FT would be higher than 21.4 ng/dL you posted if it was calculated using the Vermeulen method.

In order to know where your FT truly sits you would need to have it tested using the most accurate assay the gold standard Equilibrium Dialysis especially in cases of altered SHBG.

If you do not have access to such which is highly unlikely unless you love outside of the US than you would need to use/rely on the next best testing method the go to calculated linear law-of-mass action Vermeulen (cFTV) which will give a good approximation.

With a high-end trough TT 865.3 ng/dL and very low SHBG 8 nmol/L it is a given that your trough FT would be very high as in 30+ ng/dL.

If we calculated your FT using the go to cFTV which is available online to the general public for free with a high-end trough TT 865.3 ng/dL, low SHBG 8 nmol/L and Albumin 4.3 g/dL (default) than your trough FT 31.8 ng/dL would be very high.

Keep in mind your peak TT and more importantly FT will be higher.

As I have stated numerous times on the forum over the years you always need to be mindful of your injection frequency/where trough FT sits.

FT <5 ng/dL would be considerd low.

FT 5-9 ng/dL would be considered the grey zone where some men may experience symptoms of low-T.

FT 10-15 ng/dL would be healthy.

FT 20-25 ng/dL would be high-end/high!

The majority of men will do well with a trough FT 15-25 ng/dL depending on the injection frequency.

Most doctors truly in the know even the ones in Canada would be aiming for a trough FT 15-25 ng/dL or 522-869 pmol/L if the goal was to hit a healthy/high trough FT 15-25 ng/dL.

Need to keep in mind that there is a big difference between one running a high-end/high trough FT 20-25 ng/dL injecting daily vs twice-weekly vs once weekly.

Also going to be a big difference in peak--->trough on said protocol!

Many tend to overlook this and gun for a high-end/high trough FT only to end up struggling with sides especilly in the long run.

Just to put this in perspective most healthy young males would be hitting a cFTV 13-15 ng/dL or 10-12 ng/dL tested using the most accurate assay the gold standard Equilibrium Dialysis and this is a short-lived daily peak to boot!

Even if you take those natty outliers in the 97.5th percentile hitting a high FT 25.3 ng/dL again this is a short-lived daily peak to boot!

You have guys on T hitting a trough FT 25-30+ ng/dL injecting daily with FT elevated 24/7, EOD as in every 2 days (48 hrs post-injection),twice-weekly as in every 3.5 days (84 hrs post-injection), once weekly as in 7 days post-injection.

As you can see with a high-end trough TT 865.3 ng/dL and low SHBG 8 nmol/L you are easily hitting a very high trough cFTV 31.8 ng/dL.

Bottom line here is if you felt great overall, minus any sides and your blood markers where healthy especially RBCs, hemoglobin and hematocrit then I see no issue with where your high trough FT sat.

Yes you would easily have had room to bring down your trough FT if need but when you made the move you most likely made too big of a jump lowering your dose as your went from 140 mg--->93.3 mg/week which is a huge drop.

If anything you should have titrated down 20-25 mg T/week as this is the most sensible move when increasing or decreasing the dose.

You lowered your dose by a whopping 46.7 mg T/week which would easily have a huge impact on dropping your TT and more importantly FT.

Your trough FT is still going to be in a healthy range but much lower than the trough cFTV 31.8 ng/dL (1103 pmol/L) you were hitting on your previous protocol 140 mg T/week (60 mg every 3 days).

If anything you should have went with 120 mg T/week.

You never even posted labs so we have no idea where your trough FT sits on your current protocol 93.3 mg T/week (40 mg every 3 days) which has you feeling not so stellar!

Post a screenshot or pdf of your most recent labs!

I need a much higher dose to feel good too. Thankfully I use defy medical. I'll show you my latest posted Labs.

On a dose of 120 mg/week (which is considered a very reasonable dose by many people) you felt great and your bloodwork was good. But since your doctor is an idiot(at least on this front) he reduced your dose by 33%(120 down to 80) and afterwards you started experiencing symptoms of low t.

My personal advice opinion would be to not overthink at is this situation isn’t complicated. Go back to the dose that worked and find a new doctor.


Edit to add - calling him an idiot might be a bit harsh. It’s quite possible his actions are just being driven by insurance or other forces. Though it’s also quite possible he is misinformed

Still caught up on that TT?

Doing reruns here.

Might want to point out that you have high SHBG 57.5 nmol/L so you would need to hit a high-end/very high TT 915-1345 ng/dL in order to hit a healthy/high FT 15-25 ng/dL.

Even then not sure why you are so thankful here as the most critical fraction your FT was never even tested using an accurate assay as Defy is still clueless when it comes to testing FT seeing as they still use/rely on that known to be inaccurate direct IA (CLIA/RIA).

With a very high TT 1482 ng/dL, high SHBG 57.5 nmol/L and Albumin 4.3 g/dL your cFTV 28.5 ng/dL would be high.

Even then you are injecting daily so even though you are hitting a high FT this is a daily trough which is a far cry from someone hitting a high FT injecting twice-weekly or better yet once weekly!

Your peak--->trough would be minimal and your blood levels are very stable throughout the week.

Did he really need the higher dose?

He has absurdly low SHBG and it looks as though he was gassed up on T off the hop as he was started on 140 mg T/week (60 mg every 3 days) and if he would have had his FT tested using the most accurate assay the gold standard ED it would have most likely come back much higher than his high-end trough FT 21.4 ng/dL (742 pmol/L).

Even then I calculated his FT using the next best testing method the go to linear law-of-mass action Vermeulen (cFTV) which has his trough FT 31.8 ng/dL (1103 pmol/L) very high.

So he was gassed up off the hop and could never truly state he needed higher levels to feel good.

Compared to his previous protocol where his dose was lowered drastically from 140 mg T/week (60 mg every 3 days) to 93.3 mg/week (40 mg every 3 days) he can make that claim as the huge drop in dose would have. a big impact on driving down his trough FT!

The more sensible move here would have been going from 140-120 mg T/week not <100!

Many guys here pushing higher doses have never even tried doses that are physiological, so they have no idea if these doses would be better or worse than where they are now. My question to you is, have you tried doses in the 50-80 mg TC/week range? These lower doses should be split into at least two injections per week, or else use Xyosted—to avoid overly low troughs.

There are risks in dosing at 140 mg TC/week indefinitely. This is much more testosterone than any healthy male would make naturally. Even if lipids and HCT are ok for now, your crashed SHBG is telling you that this much androgen exposure is highly unnatural. Animal and human data suggest that cumulative cardiotoxicity is possible.

If you had no other options for feeling good then perhaps you could justify the uncertain risks in high doses. But it's important to first spend substantial time with serum levels closer to what you'd have naturally in good health. As @madman suggests, until your SHBG recovers you must use free testosterone to monitor your status; total testosterone will be misleadingly low.
 
Hey thanks for the answers, my SHBG was 11 pre trt so really low, i was on sustanon 0.25ml E3.5D first 3kk bloods came back good with trough free T 394 PMOL, then 5 months on enanthate 0.30 E3D it was 742 PMOL trough, i have no bloodwork of the 0.20 E3D but i waited 10 weeks and felt worse recovery, brainfog a bit, if i reduce dose is the drop linear? that would be 500 pmol trough

if youn started on Sustanon which is 250 mg/mL strength than you were injecting 125 mg T/week (62.5 mg every 3.5 days).

How many weeks after starting the Sustanon were labs done?

You stated 3kk so if you meant weeks then you had not even reached steady-state yet due to the PK especially seeing one of the esters used in Sustanon is decanoate so your trough TT and more importantly FT would have been higher 6+ weeks in.

Even when using medium acting esterified TC/TE it will take 4-6 weeks to reach steady-state due to the PKs.

When you switched over to the TE injecting 140 mg T/week (60 mg every 3 days) you were not hitting a trough FT 742 pmol/L (21/4 ng/dl) as your FT was never tested using an accurate assay the gold standard ED.

Your trough FT would have been much higher!

Your results were most likely tested using the known to be inaccurate direct immunoassay (CLIA/RIA) or calculated using a modified Vermeulen.

I already calculated your FT using the next best testing method the go to linear law-of-mass action Vermeulen (cFTV) using the official website which is available online for free to the general public.

Again with a high-end trough TT 865.3 ng/dL and very low SHBG 8 nmol/L it is a given that your trough FT would be very high as in 30+ ng/dL.

If we calculated your FT using the go to cFTV with a high-end trough TT 865.3 ng/dL, low SHBG 8 nmol/L and Albumin 4.3 g/dL (default) than your trough FT 31.8 ng/dL (1103 pmol/L) would be very high.

You have 2 options when it comes to testing the most critical fraction free testosterone.

The gold standard testing method is Equilibrium Dialysis.

In order to know where your FT truly sits you would need to have it tested using the gold standard ED especially in cases of altered SHBG (high or low).

If you do not have access to such which is highly doubtful if you live in the US then you would need to use/rely on the next best testing method which would be the go to linear law-of-mass action Vermeulen (cFTV) which will give a good approximation.


Seeing as you were started on Sustanon (mixed esters) than you would live outside of the US so the default method for testing FT used by those in the know would be the go to calculated Vermeulen method or worse case scenario many doctors are still using/relying on the known to be inaccurate direct IA (CLIA/RIA).

Again chances are your FT was tested using the known to be inaccurate direct immunoassay (CLIA/RIA) or a modified Vermeulen which should not be used/relied on.

You need to use the calculator from the official website.

Again your trough cFTV 31.8 ng/dL or 1103 pmol/L was very high.

You were hitting a very high trough FT 3 days post-injection which means your peak TT and more importantly FT would be higher.
 
Sorry guys. It's Sunday and it's been a long busy day. I don't have time to reply to everyone but I was just giving example what I do to feel good. Just recently I ran my levels very low and I felt terrible. I know other members like you that need lower levels to feel good, but I'm sorry to disappoint you. I need higher levels than you I'm sure when I was young and having lots of babies my testosterone levels were through the roof and I still need them levels today to feel like I did when I was a young man.

Hey, i meant 3 months on sust and 5 on enanthate, im wondering what the appropriate dosing would be then? im. suffering from really bad autonomic problems now because ive been on sustanon 2 weeks again since i had problems ordering enanthate and i ran out, panic attacks heart racing etc, propranolol is a life safer even 5mg, im getting my enanthate tomorrow and ive skipped doses of sust and not injected past 4 days, messed me up i didn’t think id have to adjust again but its the rollercoaster messing me, already prone to anxiety and sensitive nervous system, im just wondering what dose i continue, maybe even the same 0.20 E3D and check bloodwork after 2-3 monthd

If you truly felt great overall and were not experiencing any sides, blood markers were in check especially hematocrit when you were injecting 140 mg T/week (60 mg every 3 days) which had you hitting a very high trough cFTV 31.8 ng/dL (1103 pmol/L) then you should have just stick with it.

You already dropped your dose too much off the hop going from 140 mg T/week (60 mg every 3 days) to
93.3 mg T/week (40 mg every 3 days) which had you feeling not so stellar 10 weeks in and chances are you would have not felt any better if you had given it more time and unfortunately you never had labs done so we have no idea how much lower your trough FT ended up seeing as your weekly dose was decreased by a whopping 46.7 mg/week.

Even then you could always try 120 mg T/week which would most likely still have you hitting a healthy/high-end trough FT.

Not the end of the road here as you would always have room to increase it further if need be but chances are you may very well end up feeling just as good.

With an absurdly low SHBG 8 nmol/L you would only need to hit a trough TT 430-692 ng/dL in order to hit a healthy/high trough cFTV 15-25 ng/dL.

Highly doubtful one would need to push their trough FT much higher in order to experience relief/improvement of low-T symptoms let alone reap the beneficial effects of having a healthy FT.

Do what you feel is best for you!

Also keep in mind next time you get labs done once you have reached steady-state (4-6 weeks) on your new dose forget testing your FT at the lab you are using and use the go to calculated linear law-of-mass action Vermeulen (cFTV).


Just need to make sure that you test TT, SHBG. and Albumin then you can calculate your FT.

If you do not test albumin then you can just use 4.3 g/dL (default).

If you had access to testing your FT using the most accurate assay the gold standard Equilibrium Dialysis then I would tell you to always use/rely on it when testing your FT!

Hey, thanks for the answers i wanna make clear that i i used 175mg/wk with the 0.30 ml e3d because 1ml is 250mg, did you confuse with 200mg? and im wondering if i should try something inbetween the 0.20-0.30 like 0.25. my levels have crashed now i think its been 5 days since last 0.05ml sustanon and i cannot inject it anymore the rollercoaster messes me up badly, i rather stay lowish now and wait for my enanthate, my levels probably went really high because i continued E3D sustanon after last enanthate dose with same amount 0.20 e3d, ive heard of the different calculations for free T and i dont know which one is used in Finland it might be veremeluen

Okay I see now even though you started on the Sus250 when you switched over to TE it was 250 mg/mL strength whereas I thought it was 200 mg/mL.

Was it Testoviron?

Okay this changes things a bit here as you were injecting 175 mg T/week .30 mL (75 mg E3D) not 140 mg then you dropped the dose down to 116.7 mg T/week .20 mL (50 mg E3D).

You still made too big of a jump lowering your dose as you went from 175 mg--->116.7 mg/week which is a huge drop.

Again you should have titrated down 20-25 mg T/week as this is the most sensible move when increasing or decreasing the dose.

You lowered your dose by a whopping 58.3 mg T/week which would easily have a huge impact on dropping your TT and more importantly FT.

Yes when you get back on the TE you can start with 145.8 mg T/week .25mL (62.5 mg E3D) or 151.7 mg T/week .26 mL (65 mg E3D).

Wait 6 weeks then test your trough TT and make sure to test SHBG then use the online calculator to see where your trough FT sits.

Would be wise to make sure that the most accurate assay TT (LC-MS/MS) is used as it should be available to you.

Yes your FT was most likely done using the calculated method but again you need to use the official calculator (cFTV) which is available online otherwise your FT result will most likely come back lower than where it really sits judging by your previous blood work.

Do not get your FT tested!

Yes your FT was most likely done using the calculated method but again you need to use the official calculator (cFTV) which is available online otherwise your FT result will most likely come back lower than where it really sits judging by your previous blood work.

Do not get your FT tested
Hello, ive had my SHBG and my S-testo (total t) was 30 nmol and shbg 8 nmol, albumin was 4.3 when i first started trt havent checked it again, these were in the same test as the 742 pmol free T. the calculation gave me 1250 pmol, in finland i havent seen above 500 pmol free T naturally, and i heard the finnish test is more accurate and the other methods actually overesimate it, is that correct? and maybe thats the reason its rare to see over 500 pmol, and even 250 pmol can be good for someone without symptoms if tested in Finnish lab, i had all the symptoms at 168 pmol, total t 7.5 nmol, but which test is the ”real” one? ive heard of Ly handelsman/andersson/vermeluen which all give diff values, chatgpt says this:
  • Direct assay (742) → biased low
  • Vermeulen calc (1250) → biased high (especially with SHBG 8)

Ignore the FT result from your labs especially if it was the direct immunoassay.

No one should be using/relying on the known to be inaccurate direct immunoassay (CLIA/RIA).

Post a screenshot or pdf so I can see which testing method was used and chances are it was the direct IA or a modified Vermeulen which had you hitting a trough FT 742 pmol/L or 21.4 ng/dL.

I already let you know that seeing as you do not have access to the most accurate testing method for free testosterone the gold standard Equilibrium Dialysis then you would need to use/rely on the next best testing method which would be the calculated linear law-of-mass action Vermeulen (cFTV).

You need to use the calculator from the official website which is available online for free to the general public.

This is the go to calculator used by those in the know as in top experts in the field if they do not have access to to the gold standard ED which is more common if you live outside of the US.

As I have stated numerous times on the forum you always have the option of using/relying on calculated FT which would be the linear law-of-mass action cFTV as it has already been validated twice (1st time was done using TT/SHBG assays no longer available) and was eventually re-validated again using a current state-of-the-art ED method (higher order reference method) let alone more recently against CDCs standardized Equilibrium Dialysis assay.

Yes it tends to overestimate slightly but it is nothing to fret over!


*Calculated free T using high-quality T and SHBG assays has been considered the most useful for clinical purposes [99]. All algorithms suffer from some inaccuracies, including the variable quality of SHBG IAs[100], not replicating the non-linear nature of T-SHBG binding, different and inaccurate association constants for SHBG and albumin binding [101], and variable agreement with equilibrium dialysis results[99,100]. However, until further developments in the field materialize, the linear model algorithms [in particular, the most used Vermeulen equation [102]] appear to give, despite a small systematic positive bias, acceptable data for the clinical management and research[37,103].


Again if we use the online calculator and plug in your high-end trough TT 865.3 ng/dL, very low SHBG 8 nmol/L and Albumin 4.3 g/dL (default) then your trough FT 31.8 ng/dL or 1103 pmol/L is very high!

It is a given that with a high-end trough TT and very low SHBG your trough FT would be very high.



Your trough cFTV 31.8 ng/dL or 1103 pmol/L

You need to use the reference range for the cFTV which is 6.5-25 ng/dL.

Most doctors truly in the know would be aiming for a trough FT 15-25 ng/dL or 522-869 pmol/L if the goal was to hit a healthy/high trough FT 15-25 ng/dL.
