Sermorelin is the first 29 amino acids of GHRH — the smallest fragment retaining full GHRH activity. The longest-used GHRH analog in clinical settings, originally for pediatric growth-hormone deficiency and now widely studied in adult anti-aging research.
Every KINETYX vial is filled in a controlled cleanroom and sealed with tamper-evident packaging. Batch documentation includes identity confirmation, HPLC purity analysis and concentration verification.

Sermorelin (GRF 1-29) is the first 29 amino acids of endogenous growth-hormone-releasing hormone — the smallest fragment that retains full GHRH biological activity.
It has the longest clinical safety record of any GHRH analog, originally approved for pediatric GH deficiency and now used extensively as a research reference peptide in adult body-composition, sleep, and longevity studies.
Sermorelin binds the GHRH receptor on pituitary somatotroph cells, stimulating endogenous synthesis and pulsatile release of growth hormone.
Because it works upstream of the pituitary, physiologic feedback loops remain intact — negative feedback via somatostatin still limits over-release, reducing desensitization risk.
• Stimulates endogenous GH and IGF-1
• Preserves pulsatile release and feedback
• Improves sleep architecture and recovery
• Long clinical safety record vs. other GHRH analogs
Common research dosing: 100–300 mcg subcutaneously pre-bed, often paired with a GHRP such as Ipamorelin.
1 vial = 5 mg. At 300 mcg/day, a vial covers ~16 days.
Facial flushing at higher doses
Injection-site sensitivity
Occasional headache in first days

Purity is the reason I keep coming back. Third-party HPLC on file is a huge trust signal.
Great communication from the team when I asked about batch documentation. Would order again.
