    IM Quad Injections

    For me it was like having a small ball under my skin and with shallow IM I have no negative side effects whatsoever. Especially in the delts they’re 100% pain free, and glutes are very fine too. So I rotate every injection left delt than left glute than right delt and right glute and so on.

    IM Quad Injections

    And I backload the insuline syringes very carefully. As I get 1 ml small bottles of test E , I load about 10 syringes at the time. And use them as prescribed. So 25 mg per syringe and it works fine with me. I tried SC but didn’t liked it.

On the AI I see your point, obviously there many people against and pro AI. But I think we all should go by how we feel and possible side effects. In my case...

    Lab Work - What to Track in the Future?

    Thank you, but is it to be expect that T levels will be somewhat returning to same as on IM ? How long I should expect to return? Could this drop in levels also be related to the fatigue or Muscle soreness I have right now? According my doctor optimal estradiol level should be arround 25, but...

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.
