Subcutaneous insuline needle smallest gauge

Do you use cotton seed oil?


Delatestryl (enanthate), sesame oil.

In the past used Depo-Testosterone (cypionate), cottonseed oil injecting with a 28G, and no issues.

The benzyl alcohol that is added also has a beneficial effect on reducing the viscosity of the carrier oil.
 
Is use a 31g 5/16" syringe stright into the butt fat for subq with TCYP every MWF. I've been doing it this way for ~9years. My labs show T at 800-1100 depending on how many days from the last tcyp shot.
 
I'm using 27 gauge 1/2" insulin syringes (fixed needle). Takes a bit to draw Depo-Test as the oil is thick. Most compounded Test Cyp uses a thinner oil, so you can get away with using something like a 30 gauge 1/2" needle.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
