Sermorelin
The original GHRH analog. Studied since the 1980s.
A 29-amino-acid peptide that triggers the body's own natural growth hormone release — the most-established GH peptide in modern research.
The Simple Version.
Cutting through the jargon — here's what Sermorelin is and why it's been the foundational GH peptide in research for over 40 years.
Sermorelin is the original growth hormone releasing hormone (GHRH) analog.
- It's a 29-amino-acid peptide — a synthetic version of the first 29 amino acids of human GHRH, which is the natural hormone your body uses to release growth hormone.
- First synthesized in the 1980s — making it one of the oldest and most-established GH research peptides with decades of published research backing it.
- It triggers the body's own natural growth hormone pulse — meaning it works WITH your body's existing hormonal rhythms rather than replacing them like synthetic HGH.
- Considered the gold standard for GHRH research — newer peptides like CJC-1295 are modifications of the same GHRH structure that Sermorelin pioneered.

Three Reasons Researchers Still Choose Sermorelin.
Even with newer GH peptides on the market, Sermorelin remains the foundational research peptide. Here's why.
Most Researched
Referenced in published research since the 1980s. More long-term research data than any other GHRH analog — making it the safest known baseline for GH research.
Natural Pulse
Studied for triggering the body's own GH pulse — the foundational mechanism behind every modern GH research peptide that came after.
Short Half-Life
Sermorelin's shorter half-life is preferred in research protocols studying GH pulse frequency — vs CJC-1295's modified longer-lasting profile.
Sermorelin has been studied in published GH research since the 1980s — making it the most-established GHRH analog in modern research.

Every Batch is Tested.
We don't just say "99% purity" — we show you the test results. Public COAs from real third-party labs, no email gate.
Why HaloAmino Exists.
"For years, the peptide industry has been charging $80, $90, even $120+ per vial for the exact same research compounds — while hiding COAs behind email gates, shipping 7+ days from overseas, and treating customer service like an afterthought. I built HaloAmino because researchers deserved better. Every batch tested. Every COA public. Every order shipped same-day from the US. No gimmicks."
Built Better Than Competitors.
Same research peptide. Better purity, better testing, better experience.

Sermorelin FAQ.
Is this real Sermorelin or fake?+
Every batch is independently tested by Janoshik Analytical — one of the most trusted third-party peptide testing labs. We publish the full COA publicly on our site for every batch — no email or login required. If a vendor won't show you a real COA, that's a red flag. Ours is right there.Sermorelin vs CJC-1295 — what's the difference?+
CJC-1295 is essentially a modified version of Sermorelin with an extended half-life. Sermorelin is the original 29-amino-acid GHRH analog (studied since the 1980s). CJC-1295 is a modification of the same molecule designed to last longer. Researchers choose Sermorelin for pulse-frequency research, CJC-1295 for sustained GH research.Why use Sermorelin if CJC-1295 exists?+
Three reasons: (1) Sermorelin has 40+ years of published research data — the most-established GHRH analog in research. (2) Its shorter half-life is preferred in research protocols studying natural GH pulse frequency. (3) It's the foundational peptide that newer GH peptides are modifications of — making it the "baseline" reference compound in GH research.What is Sermorelin used for in research?+
Sermorelin is studied as a GHRH analog — meaning it triggers natural growth hormone release through the GHRH receptor. It's referenced in published research on GH pulse frequency, natural GH release, and pituitary function research. Important note: It's sold strictly for research use only.What makes HaloAmino different?+
Three things: public COAs on every batch (no email gate), 99%+ purity standard verified by Janoshik Analytical, and same-day US shipping. We test more aggressively, ship faster, and don't hide our results behind a login wall like most peptide vendors do.How fast does this ship?+
Orders placed before 12pm ET process the same business day. Standard US delivery is 2–5 business days. All orders ship in plain, discreet packaging from our US warehouse — never internationally. Free shipping on all orders $99+.What if my vial arrives damaged?+
We'll replace it free, within 30 days of delivery. Just email us a photo of the damage and your order number — most claims are resolved within 24 hours. No restocking fees, no questions, no return shipping.Is this for human consumption?+
