How it works
Sermorelin is a synthetic peptide corresponding to the first 29 residues of human growth hormone-releasing hormone (GHRH 1–29), the active fragment of the full 44-residue native peptide. It engages the GHRH receptor on anterior pituitary somatotrophs, stimulating endogenous GH release in a pulsatile, physiological pattern. Half-life is short — approximately 10–20 minutes — favoring evening administration in protocols designed to align with circadian GH secretion.

Storage & handling+
Lyophilized: −20°C, 24 months. Reconstituted: 2–8°C, use within 14 days — Sermorelin is less stable in solution than many peptides due to oxidation-sensitive methionine residues. Bacteriostatic water.
We ship in insulated parcels with phase-change cooling and a tamper-evident seal.
FAQs+
How does Sermorelin differ from CJC-1295?+
Both are GHRH analogs. CJC-1295 has structural modifications (DAC variant) that extend its half-life from minutes to days. Sermorelin's short half-life mimics native GHRH pulsatility.
Why is Sermorelin in Anabo rather than its own category?+
Anabo at hábit covers anabolic and recovery research broadly — growth signaling, tissue repair, connective-tissue work.
Why is the post-reconstitution shelf life shorter?+
Methionine residues susceptible to oxidation. Cold storage and a 14-day window minimize potency loss.
What's the typical reconstitution concentration?+
Common preparation: 2 mL bacteriostatic water per 10mg vial, yielding 5 mg/mL.
Is Sermorelin subscription-eligible?+
Yes. 15% off on a 60-day cycle.
Does Sermorelin produce the same downstream effects as exogenous GH?+
Similar in research models (IGF-1 elevation, etc.) but the route differs — Sermorelin works through endogenous secretion, preserving negative-feedback regulation.

Verified buyer notes
Initials only — every quote is verified against an order record. We don’t ghost-write reviews.
“COA matched what we ran in-house. Powder reconstituted clean, no haze. Did exactly what we needed it to.”
“Switched after two bad lots from a previous source. Three orders in, zero issues.”
“Asked support a purity question and got the raw HPLC trace back within the hour. That transparency is why we reorder.”
