Typical Research Protocol
  • Starting dose: 0.5–1mg weekly
  • Titration: increase by 0.5mg every 4 weeks
  • Maintenance: 4–8mg weekly (subject-dependent)
  • Reconstitute with bacteriostatic water
Storage

Store lyophilised powder at 2–8°C. After reconstitution, refrigerate and use within 28 days. Do not freeze reconstituted solution.

Growth Peptides
Ipamorelin vial
Growth CoA Verified · 99.9% Purity

Ipamorelin

Selective growth hormone secretagogue — increases GH pulses without elevating cortisol or prolactin.

£34.99

inc. 20% VAT

In Stock · Ships within 24h
★★★★★(167)
Mechanism

Ipamorelin selectively binds ghrelin receptors in the pituitary, triggering pulsatile GH release without stimulating cortisol, prolactin, or ACTH — making it one of the cleanest GH secretagogues in research.

Typical Research Protocol
  • 200–300mcg injected 2–3× daily
  • Best administered fasted or before sleep
  • Commonly stacked with CJC-1295 for amplified effect
  • Cycle: 8–12 weeks
