Core Effects

Dihydrotestosterone (DHT) is a naturally occurring androgen that is widely used in androgen replacement therapy, muscle firmness, and strength enhancement research due to its high androgenic activity and non-aromatization properties .

✅ Potent androgenic effect :

High androgen receptor affinity , 2-3 times more potent than testosterone

Promote masculinity and maintain secondary sexual characteristics

✅ Non-aromatizable properties :

Not converted by aromatase , no risk of estrogen-related side effects

Does not cause water retention , maintains muscle hardness and separation

Topical application advantages :

Promote hair growth and treat male pattern baldness

Increase muscle density , improve muscle mass and strength

✅ Advantages :

No estrogen side effects , avoids estrogenic milk and water retention

Strong androgenic activity , quickly improving athletic performance
