Sermorelin
The first 29 amino acids of GHRH, the shortest piece that still works.
4.7 · 24 reviews≥ 99.2% HPLCLab-verifiedResearch only
Buy sermorelin as a research-grade GHRH analogue (GRF 1-29) at ≥99% HPLC purity, dispatched the same working day from the Netherlands. In research it prompts the pituitary into releasing growth hormone of its own. Intended solely for laboratory research.

Of the growth-hormone-releasing hormone GHRH, the first 29 amino acids are enough to keep the full action, and that piece is exactly what sermorelin is. As a GHRH analogue it adds no ready-made growth hormone but gets the pituitary to make more of its own. We supply it as a research-grade vial at ≥99% HPLC purity, dispatched the same working day from the Netherlands. Explicitly a research raw material for the lab, not for human use.
What sermorelin research turns on
In research, Sermorelin is about the growth hormone axis. It is a short peptide resembling GHRH, the body's own hormone that prompts the pituitary to release growth hormone. Sermorelin is thought to mimic that same signal: it prompts the pituitary to release a pulse of growth hormone itself, rather than delivering the hormone from outside. Researchers therefore use it to study the body's own growth hormone release. At BasePurity you buy it purely as a research raw material, not for use in humans.
Why 29 amino acids are enough
Sermorelin matches the first 29 amino acids of GHRH — hence the name GRF 1-29. That is the shortest fragment that keeps the hormone's full action. It is thought to act on the GHRH receptors in the pituitary and so prompt the production and release of growth hormone. What is special is that it leaves the natural feedback intact: the body keeps watch on the brake itself, unlike with directly administered growth hormone. Most of what we know comes from clinical and pre-clinical research.
One step earlier than growth hormone itself
The difference from growth hormone itself is where Sermorelin sits in the chain. Growth hormone (hGH) is the end product; Sermorelin sits a step earlier, as the signal that prompts its production. In research that is an interesting distinction: where direct hGH imposes the amount from outside, a GHRH analogue like Sermorelin lets the body set the pulse and rhythm itself. We supply Sermorelin as a research-grade vial so that exact route can be studied — not as hormone replacement.
Placed next to CJC-1295, tesamorelin and ipamorelin
Sermorelin isn't alone: it belongs to a family of peptides around the growth hormone axis, and in research they are often compared. CJC-1295 is essentially a modified, longer-acting version of that same GRF 1-29; tesamorelin is a stabilised GHRH analogue; ipamorelin works from another angle, as a GH secretagogue with its own point of action. Sermorelin is the classic, shortest-acting GHRH fragment. You'll find these related compounds separately in our range, with a link from this page.
On amounts and making it up
We deliberately leave the amount open: Sermorelin is a research compound, and we don't provide human dosing advice. In the literature it is usually studied in small amounts per protocol, after reconstitution with bacteriostatic water. Need to convert amounts for a research setup? We have a dedicated calculator for that. Keep the reconstituted peptide refrigerated and use it within the recommended window.
What is known about tolerability?
Sermorelin is known in research for a mild profile. In the studies that have been done it was generally well tolerated, and mostly mild reactions were reported — such as redness or irritation at the injection site, or sometimes headache. Because it leaves the natural feedback intact, release is more regulated than with direct growth hormone. Large long-term data in humans is lacking.
What is legally allowed?
In the Netherlands you may buy and sell Sermorelin for experimental laboratory research that isn't applied to humans or animals. For athletes, it's important to know that compounds affecting growth hormone release are on the WADA prohibited list and so banned in competition. We supply Sermorelin strictly as a research-grade compound, not as a medicine.
Why we test every batch
With a peptide, reliable research hinges on one thing: knowing the vial contains what the label says. That's why we test every batch of Sermorelin by HPLC for ≥99% purity and for identity, with a COA per lot, and ship it freeze-dried so it reaches you stable. That way you know exactly what you're holding — the exact specifications are in the table at the bottom of this page.
