    How to inject Testosterone Cypionate

    I'm going to try. Is there really no difference at all between I'M and SubQ? One doesn't have a slight advantage over the other? I've dealt with low T for so long now, and since I've finally been prescribed the injections, I want to do everything to the best of my ability.

    How to inject Testosterone Cypionate

    Thanks for everything Vince. I am already injecting air into the vial, but I will now try warming it first to see if I can do away with the 18 gauge needles. I don't get the big vial that the guy used in the video. CVS gives me four small bottles (1 month supply) of Test Cypionate and the...

    How to inject Testosterone Cypionate

    Hey Blackhawk, Honestly, I didn't even know what IM and SubQ meant until I just looked them up. And yes you're right, I thought injecting the test directly into the muscle was the only way, but after reading how many people use the SubQ method, I plan on trying and hopefully sticking to this...

    How to inject Testosterone Cypionate

    Hey Vince, I bought the needles from cvs (they only allow 10 per day to be purchased here in NY, I guess to combat heroine users) I use an 18 gauge to draw the testosterone cypionate and a 23 gauge to inject it. But I may try a 21 gauge since it takes forever using a 23 gauge to administer.

    How to inject Testosterone Cypionate

    I'm not sure what an easy gauge is. But 29 seems very small. I'm using a 23 gauge, and it's somewhat difficult to administer because the oil is kind of thick. Heck, I can't even draw the test cypionate with the 23 gauge, it won't come out. I have to use an 18 gauge and then swifch the 18 out for...

    How to inject Testosterone Cypionate

    Thanks guys, I was nervous because when I pulled the needle out this morning on my latest dose, blood shot out (not far but a couple of inches) but once I applied pressure it stopped. I know test cyp needs to be administered into the muscle to work properly. But what would happen if it were...

    How to inject Testosterone Cypionate

    Hey guys. I've been taking 200mg/ml of Testosterone Cypionate for just about a month now. So far I've given myself 4 total injections, 2 in butt muscle, and the following 2 in thigh. Once in each location, when I removed the needle, a lot of blood came following. Im guessing this is because I...

    New to TRT, I have a few questions for anyone willing to help (sorry for long post)

    Thank you everyone for your advice, you especially Orrin. The amount of information you have provided is substantial and I definitely need to begin reading up. A few years back when I first suspected I had Low T, I read up on the symptoms, and some basic knowledge, but this forum has shown me...

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.
