    Étude clinique pharmacocinétique : phénylpropionate de nandrolone (NPP) montre une libération plus rapide que le décanoate (pic 24-48 h, demi-vie effective ~2,5 jours) — schéma EOD ou 3×/sem nécessaire pour maintenir un résiduel stable.

    Étude de référence : la nandrolone partage les mêmes affinités tissulaires que le décanoate (même molécule active), ratio anabolique/androgénique 125/37, faible activité androgénique au niveau cutané et prostatique via 5α-réduction en DHN.

  3. Kicman AT (2008). Pharmacology of anabolic steroids. British Journal of Pharmacology. doi: 10.1038/bjp.2008.165

    Revue de pharmacologie : le NPP partage les propriétés pharmacodynamiques du Deca (aromatisation faible, activité progestative résiduelle) mais avec une cinétique plus courte qui facilite la sortie post-arrêt et le timing PCT.

  4. Pope HG Jr, Wood RI, Rogol A, et al. (2014). Adverse health consequences of performance-enhancing drugs: an Endocrine Society scientific statement. Endocrine Reviews. doi: 10.1210/er.2013-1058

    Énoncé Endocrine Society : le NPP partage le profil d'effets indésirables de la nandrolone (gynécomastie progestative, dysfonction érectile possible, modifications lipidiques) — la cinétique plus courte facilite l'arrêt mais ne change pas la nature des effets.
