Jesus how is this thread 15 posts long?

We’re just confusing people at this point.

.4ml = .4cc

LoL!!

Let's shoot for 100.

I just received my medication and I'm a bit confused. I have 2x 5mL bottles of 200mg/mL test cyp. I am on a .1ml daily dose (which should be 20mg daily) I purchased easy touch u-100 27g .5cc 1/2" syringes per a suggestion in another thread. Problem is I'm sadly getting completely lost in the math of this. If my math is correct I have 2x 5mL bottles to make 10mL total. Each bottle is 200mg per mL so that's 2000 total mg of test between both bottles. Dividing that by my daily does 20mg is 100 doses which will get me to my next consult at 90 days. 10mL of liquid divided by 100 doses works out to the .1ml daily dose I was prescribed. With these being .5 cc/ml syringes is my dose the 10 marker? I don't know why if the syringe is .5cc/ml they would label the side 5/10/15... 50. Why not label it .05/.1/.15... .5?

I know its ben awhile since posted but u will never get test into that small of a syringe. Plus Test is an IM (in the muscle inj) & those tiny insulin syringes dont reach muscle. U need a 1-3 CC syringe w/ a 1 inch needle. Prob 20-23 gauge

Such advice is old and outdated!

This is not the forum for such.

Where have you been hiding?

Oil based esterified T can be injected subcutaneously!

Most in the know are using LDS insulin syringes fixed needle 27-31G various needle lengths to draw'inject the oil based esterified T solution whether injecting shallow IM or strictly sub-q!

Yes it can easily be done and may take a little longer to draw/inject depending on the amount of the oily solution being used which is based off weekly dose of T/injection frequency.

You can easily use a 1/2" needle length injecting shallow IM.

Even than you can use a 25-27G X 1" neele length to inject IM.

No one is wasting their time using those 20-23G harpoons!

LDS insulin syringes 27-31G is where it;s at!

My reply from one an older thread sums it up here:

Not sure what the fear is here when it comes to drawing/injecting using the same needle.

Should be virtually painless when drawing/injecting with the same needle 27-31G especially when using a higher gauge needle.

Yes drawing/injecting can be slower when using the higher gauge needles but it is nothing to fret over and if you are drawing/injecting low volumes of the oily solution it should be quick.

Most in the know on TTh are using an LDS insulin syringe whether 1 ml (100 unit), .5 mL (50 unit) or .3mL (30 unit) with fixed needle length (6MM, 8MM, 12.7MM) when injecting strictly sub-q or 12.7MM when injecting shallow IM.

One of the main advantages of using an LDS insulin syringe for testosterone therapy is that there will be minimal waste of medication due to low-dead space let alone you can 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, minimizing any waste of medication, easier for many to measure accurate doses when injecting lower volumes, 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”

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.

Thread 'TRT with Subcutaneous Testosterone Injections: A Safe, Practical and Reasonable Option'

Oct 26, 2021

Abstract Context: Injections with intramuscular testosterone esters have been available for almost 8 decades and not only result in predictable serum testosterone levels but are also the most inexpensive modality. However, they are difficult to self-administer and associated with some discomfort. Recently, subcutaneous administration of testosterone esters has gained popularity, as self-administration is easier with this route. Available data, though limited, support the feasibility of this route. Here we review the pharmacokinetics and safety of subcutaneous testosterone therapy...

So I’m starting my first cycle of TRT and I will be injecting subcutaneously EOD.

I understand some people use insulin needles, I’m not super comfortable with the idea of drawing and injecting with the same needle.

I’ve been looking for 0.5ml lure lock needles but haven’t found any. I’m likely going to do 27G 1/2” for the stomach fat. I’ve found 1ml lure locks but I’d prefer the half ml for exact dosing purposes.

Can anyone provide some insight?

Cycling would be for someone abusing T/AAS for the sole purpose of gaining muscle/strength beyond or better yet well...

Thread 'Hesitating on TRT, Does Anyone Have Regrets?'

Apr 11, 2025

I have two questions:

1. Can I "try" TRT long enough to see if it will work without risking the functionality I already have?

2. Does anybody have regrets for trying medically-supervised TRT when they were already pretty healthy and functional?

Background:

I'm 54 years old, 5'9", 150 lbs. I lift at the gym 4 days a week; eat 150 grams of protein a day; and walk or hike off-road 5 days a week. I don't take any prescription medications, other than Sumatriptan as needed for migraines.
