Which Type of Needles for Luer Lock Syringes?

Hypodermic needles are what you want as these are the standard detachable needles for syringes.
Forget wasting your time with the standard Luer-Lok or Slip-Tip syringes as you are going to be wasting some of your medication due to the dead space.
More importantly there is no need to use 22-25G syringes to draw/inject the oily solution as you. will need to swap out needles and you will cause more trauma/scar tissue at the injection site when injecting.
Using an LDS insulin syringe with a fixed needle (permanently attached) will allow you to draw/inject using the same needle and minimize the chance of trauma/scar tissue.
No brainer here.
Most men on T therapy are using LDS insulin syringes 27-31G various needle lengths depending on whether they are injecting shallow IM or strictly sub-q.
Numerous advantages here.
As I stated in a previous thread.
Whether one is injecting strictly sub-q or shallow IM most are using LDS insulin syringes 27-31G with various needle lengths 1/4"(6MM), 5/16"(8MM), 1/2"(12.7MM).
One of the main advantages of using an LDS insulin syringe for TTh is that there will be minimal waste of medication due to low-dead space let alone you draw/inject using the same needle (fixed).
Numerous benefits of using an LDS insulin syringe (fixed needle) as injections are virtually pain-free, minimal trauma to the tissue, minimizie any waste of medication, easier for many to measure accurate doses when injecting lower volumes of the oily solution and you can draw/inject using the same needle to boot!
“Fixed insulin type syringes have no void space at the point where the needle joins the syringe, and so are known as Low Dead Space Syringes, which is sometimes abbreviated in the literature to LDSS. They are made like this so that the full accurate dose is delivered, and there is no waste”
Thank you for your reply.
So, you are recommending insulin syringes, but how do I convert 100 ml to these units? These syringes do not have a ml scale.

Selecting the Devices
There are many different syringes and needles, suiting many different procedures. It is important to choose the needles and syringes carefully according to the type of injection to be administered. For example, the length and gauge of the needle and type of syringe must be suitable for the injection site, viscosity, and volume of medication. The size, age, and condition of the patient are other key factors in the selection process.

Thank you again, but this is way too much information for me. I was just looking a link or name of the syringes to use.

Most commonly used insulin syringes are the 1 ml = 100 units.
Most men on T therapy are using esterified TC or TE 200 mg/mL strength.
1 unit = 0.01 mL = 2 mg (esterified T)
Thank you!

What is your protocol (dose of T/injection frequency) and what ester (TC or TE)/strength (100 or 200 mg/mL) are you using?
Testosterone cypionate. I am starting with 50 every three days to get to 700. I am currently have 290.

I would cut back the dose as the standard starting dose is 100 mg T/week or the more sensible move would be 50 mg T twice-weekly.
No one needs to be started on a higher dose.
The last thing you want to do here is jack up your FT off the hop.
Many men can hit a healthy/high trough FT on 100 mg T/week split.
You may very well end up being one of them.
Would not get too caught up on your TT as FT is what truly matters here as it is the active unbound fraction of T responsible for the positive effects.
Most men on therapy are injecting 100-200 mg T/week whether once weekly or split into more frequent injections.
The majority of men can easily achieve a healthy/high trough FT injecting 100-150 mg T/week especially when split into more frequent injections.
There will always be those outliers who may need the higher-end dose 200 mg T/week but its far from common as in rare.
Even then most would never need to go beyond 150 mg T/week.
Keep in mind there are many men who can achieve stellar levels injecting <100 mg T/week especially when split into more frequent injections.
Best piece of advice here is to start low and go slow on a T only protocol so you can see. how your body reacts to T and where said protocol (dose T/injectiuon frequency) has your trough TT and more importantly FT, estradiol and SHBG let alone critical blood markers RBCs, hemoglobin and hematocrit.
Blood work will be done 6 weeks in once you achieve steady-state.
The only time your dose would be increased 6 weeks in is if your trough FT is too low. which is highly doubtful in most cases.
Worst case scenario if your trough needed to be brought up then your dose would be titrated 20-25 mg/ and blood work wold be redone 6 weeks later once you achieve steady-sate.
There will always be time to increase your dose if need be or add in hCG.
Far easier going up than having to come down.
Trust me on this one.

50 mg every 3 days is 116.7 mg/week so lower the dose slightly to get closer to 100 mg/week.
If you are going to inject every 4 days then 60 mg would be 105 mg T/week.
No need to jump in any higher.
Total Testosterone (TT) and Free Testosterone (FT).
Thank you. Good advice with the 60 mg every 4 days. Will do that.

As I stated worst case scenario here is 6 weeks in once blood levels have stabilized due to the PK esterified TC and you have blood work done making sure to test at the true trough (lowest point) before your next injection (96 hrs post-injection) if you are injecting every 4 days and your trough FT comes back too low which is highly doubtful on such dose then you can just titrate the dose upward 20-25 mg.
Chances are you will be hitting a healthy FT so you will need to give it a few more months to truly gauge how you feel overall and whether a dose increase would truly be needed.
Just so you understand how this works when first starting therapy or tweaking a protocol.
The protocol chosen (dose T/injection frequency) needs to be followed week in and week out.
When first starting therapy or tweaking a protocol (increasing/decreasing dose T) hormones will be in FLUX during the weeks leading up until blood levels have stabilized (4-6 weeks using TC/TE) and it is common for many to experience ups/downs during the transition as T levels are increasing or decreasing (when lowering T dose) and the body is trying to ADJUST.
Even then once blood levels have stabilized (4-6 weeks) it will still take the body a few months to ADAPT to its new set-point and this is the critical time period when one needs to gauge how they truly feel overall regarding relief/improvement of low-T symptoms.
Every protocol needs to be given a fighting chance to claim whether it was a success or failure.
Many make the mistake of tweaking their protocol every 6 weeks because they do
not feel good.
The first 6 weeks means nothing when looking at the bigger picture.
Patience is key otherwise you will end up chasing your tail indefinitely.
It is a common theme when starting TRT or tweaking a protocol (increasing dose T) to experience what we call the honeymoon period (euphoric like state, increased libido/erections, overall well-being) due to increasing T levels, dopamine, lighting up ARs (androgen receptors).
Unfortunately this is short-lived and temporary as the body will eventually adapt and things will level out and this will become the new norm.
Many lack the understanding of how this works and end up on that never ending merry go round chasing the honeymoon period.
After you put in the time 12 weeks to gauge how you truly feel regarding relief/improvement of low-T symptoms and overall well-being on your current protocol then you can decide if it needs to be tweaked (increase dose of T/manipulate injection frequency).
No one can say where you will end up or what protocol (dose of T/injection frequency) will be best for you!
