— About this compound

Sermorelin Acetate.

Class · GHRH receptor agonist — 29-amino-acid fragment of growth-hormone-releasing hormone

Origin. The shortest N-terminal fragment of GHRH retaining full biological activity at GHRH receptors. Synthesized and characterized following identification of full-length GHRH by Guillemin and colleagues in the early 1980s.

Sermorelin is the synthetic acetate salt of GHRH(1-29), the N-terminal 29 amino acids of human growth-hormone-releasing hormone (somatocrinin). It is the shortest GHRH fragment known to retain full intrinsic activity at the GHRH receptor and is among the most-studied secretagogues in the public research literature.

Unlike growth hormone itself, sermorelin acts upstream by stimulating endogenous pituitary GH release in a physiologic pulsatile pattern, preserving negative-feedback regulation by somatostatin and IGF-1.

— Common research applications

  • GH / IGF-1 axis research
  • Pituitary somatotroph function
  • GHRH receptor pharmacology
  • Comparative secretagogue studies

— Mechanism

How it's been studied.

Selective agonist at the GHRH receptor on anterior pituitary somatotrophs. Receptor activation triggers cAMP-mediated calcium influx and stimulates pulsatile growth hormone release from pituitary stores.

Mechanism descriptions reflect findings reported in the preclinical and basic-research literature. They are not clinical conclusions and not statements of therapeutic effect.

— How it's made

From compound to your shelf.

Every Merit lot follows the same documented path. Five steps, every one verifiable.

  1. 01

    Sourcing

    Compound starts as a research-grade API.

    Active pharmaceutical ingredient sourced from FDA-registered manufacturers. Identity confirmed against reference standard before any compounding begins.

    • API from FDA-registered manufacturers
    • Identity verified against reference standard
    • Chain of custody documented
  2. 02

    Compounding

    Sterile-filled at a 503B facility.

    Lyophilized in a cleanroom at our 503B outsourcing facility. The powder format gives ≥24 months sealed stability — no cold-chain shipping required.

    • 503B outsourcing facility, FDA-registered
    • ISO-certified manufacturing process
    • Lyophilized powder for transit stability
  3. 03

    Verification

    Every batch HPLC-tested.

    Reverse-phase HPLC-UV (UV/MS for higher-MW peptides) confirms identity and purity for every lot before it leaves the lab. The chromatogram is archived.

    • Reverse-phase HPLC, per-lot
    • ≥99% purity floor — every batch
    • Chromatogram archived for every lot
  4. 04

    Sign-off

    A US-licensed pharmacist releases the lot.

    No batch ships without a pharmacist reviewing the chromatogram, identity report, and lot documentation. The pharmacist holds the release authority.

    • US-licensed pharmacist on every lot
    • Pharmacist holds release authority
    • No batch ships unsigned — ever
  5. 05

    Dispatch

    Ships from Dallas in 48 hours.

    Vials labeled with lot ID, tested date, and CAS. Order before 2pm CT Monday–Thursday for same-day dispatch. UPS Ground, tracked + insured.

    • 48hr dispatch from Dallas, TX
    • Lot ID printed on every vial label
    • UPS Ground, tracked + insured

Every step above can be verified for any specific lot by emailing rx@meritsciences.com with the lot number from your vial label.

— Common Questions

Got questions.

Why does Merit ship lyophilized?+

Lyophilized format gives ≥24 months sealed stability at -20°C — significantly longer than pre-reconstituted, which has a 30-day shelf life once in solution. You reconstitute at the moment of use, when potency is at its peak.

How do I verify my lot's COA?+

Your vial label carries the lot number. Use that number to pull the COA on our site at any time — the COA for your specific batch lives at /coa/[lot-id] and stays accessible for the life of the product.

What does "pharmacy-verified" actually mean?+

A US-licensed pharmacist on our team reviews every batch before release. They sign off on the lot's purity, identity, and release. No batch ships without that sign-off — and that's what separates Merit from a reseller catalog.

Will my bank flag this purchase?+

Statements show as Merit Sciences LLC. Standard merchant descriptor — does not trigger category-code flags. All major cards via Stripe; PayPal accepted at checkout.

How fast does it ship?+

48 hours from order to dispatch, Monday through Thursday. UPS Ground, tracked + insured. From Dallas, TX, most US addresses receive within 3-5 business days.
