HGH — dosage, half-life & reference guide

Growth hormone peptide · also known as GH, rHGH, Human Growth Hormone, Growth Hormone, Somatropin, hGH

Recombinant human growth hormone — an identical copy of the GH your pituitary naturally produces. HGH directly stimulates IGF-1 production, promotes fat burning, muscle protein synthesis, and tissue repair. The gold standard for growth hormone optimization, with decades of clinical data. Requires careful dosing and IGF-1 monitoring — more is not always better.
