    Méta-analyse de 27 essais : la GH recombinante chez l'adulte jeune en bonne santé augmente modestement la masse maigre (+2,1 kg) sans gain de force ou de capacité aérobique sur les fenêtres étudiées (< 12 semaines), avec rétention d'eau et œdème nettement plus fréquents.

  2. Holt RI, Sönksen PH (2008). Growth hormone, IGF-I and insulin and their abuse in sport. British Journal of Pharmacology. doi: 10.1038/bjp.2008.99

    Revue de référence sur l'usage non médical de la GH chez le sportif : doses 2-10 UI/j, demi-vie courte (3-4 h) mais effets relayés par l'IGF-1 hépatique, mécanisme différentiel GH (lipolyse, rétention sodée) vs IGF-1 (anabolisme musculaire), enjeux de détection antidopage.

  3. Møller N, Jørgensen JO (2009). Effects of growth hormone on glucose, lipid, and protein metabolism in human subjects. Endocrine Reviews. doi: 10.1210/er.2008-0027

    Revue mécanistique de référence (Endocrine Reviews) : la GH est une hormone de contre-régulation qui antagonise l'effet de l'insuline — résistance insulinique, élévation glycémie à jeun, lipolyse accrue, flux d'acides gras libres ↑ — mécanisme physiologique direct, pas une toxicité.

    Synthèse sur l'acromégalie : exposition prolongée à des taux supraphysiologiques de GH/IGF-1 associée à un surrisque oncologique modéré et organe-spécifique (côlon, thyroïde) sur des décennies — plausibilité du signal mécanistique IGF-1 / prolifération cellulaire.
