    Does hCG boost libido by stimulating 5-alpha-reductase?

    Thanks for your reply, I hope your new protocol will work for you. Would be nice to have some libido and good mood I can imagine :-). I’m still dialing in and I suspect my dose is too low. At this moment I’m only taking 12mg Test-cyp plus 100iu HCG daily. As we know post Accutane guys are...

    Does hCG boost libido by stimulating 5-alpha-reductase?

    I know you both injected T SubQ and IM, did you notice a difference in libido between SubQ and IM? inject T with hCG, IM spikes my libido and mood but gives me some acne.

    Levels TT / FT / SHBG before starting TRT

    I see your point, and it’s true that dr. Stevens his ‘gold standard’ approach is HCG with testosterone from the start, preferably without an AI. I do think his approach is common sense for as far as I can judge it. As in mimicking the hormonal pattern with daily injections, to take the least...

    Levels TT / FT / SHBG before starting TRT

    Thanks for posting your precautions, I’ll certainly take them in consideration with respect to my final decision ‘To TRT’ or ‘Not to TRT’. Unfortunately I already explored several improvement routes in terms of lifestyle, excercise, bodyweight / bodyfat / diet. My testosterone sits on the low...

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.
