HGH 191aa
99.7% PURITY
RECOMBINANT SOMATROPIN

HGH 191aa

10 IU vial · lyophilized

Recombinant human growth hormone produced via E. coli expression with the full native 191-amino-acid sequence — identical to pituitary-derived somatropin. Lyophilized for stability and supplied as a pharmaceutical-grade research reference.

Half-Life

~2–3 hours (effects extend via IGF-1 cascade for 24+ hours)

Storage

Lyophilized: 2–8 °C, protected from light. Reconstituted: 2–8 °C, use within 21 days.

Who it's for

Longevity and somatopause researchers replicating endogenous nocturnal GH release.

Key things to know

  • Reconstitute with bacteriostatic water — inject slowly down the vial wall.
  • Pulsatile evening dosing best mimics natural pituitary rhythm.
  • Lean mass and lipolysis effects cascade through IGF-1 — full results take 8–12 weeks.
  • Glucose handling can shift; pair research protocols with glycemic monitoring.
Research Highlights
  • Cornerstone of longevity and somatopause-replacement literature
  • Pulsatile dosing mimics endogenous nocturnal GH release patterns
