Journal of Gerontology: Series A — Biological Sciences and Medical Sciences. doi: 10.1093/gerona/gls078

    RCT phase I (76 hommes sains, 21 jours, 0,1 à 1 mg/j) : LGD-4033 augmente la masse maigre dose-dépendamment et supprime fortement la testostérone totale, la SHBG, le HDL et les triglycérides — effet pharmacologique humain confirmé à très basses doses.

    Revue systématique : LGD-4033 (ligandrol) demi-vie 24-36 h, profil suppressif marqué supérieur à l'ostarine à dose musculation, élévations ALAT et baisse HDL — recul long terme inexistant.

    Revue mécanistique : LGD-4033 figure parmi les SARMs à ratio anabolique/androgénique très favorable in vitro (100/10), avec une affinité élevée au récepteur androgène musculaire et une activité minimale au niveau prostatique.
