    Tesamorelin plus ipamorelin blend- Do I need to cycle them?

    I honestly think low dose tirzepatide plus TRT can have better efficacy in reducing visceral fat if a high protein diet and 4 days a week resistance/cardiovascular exercise program is undertaken.

    Arimidex daily vs twice weekly

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.
