Shop Sermorelin Acetate 10 mg With Lot Data and Chemical Identity

Order sermorelin when the study needs the GHRH receptor activated by the unmodified sequence. The 10 mg vial is held in Australia with HPLC data for every lot, and the sections below cover identity checks, mixing and the choice against stabilised analogues.

What Is Sermorelin?

Sermorelin is a copy of the first 29 amino acids of the brain's own growth hormone releasing signal, made synthetically and left exactly as nature wrote them. It is the smallest piece of GHRH that still works at full strength, which makes the sermorelin peptide the plainest available way to switch on the GHRH receptor in a pituitary model.

Found in a tumour, not a brain

The story behind sermorelin is stranger than most. Physiologists had suspected for decades that the hypothalamus sent a releasing factor for growth hormone, but the quantities in brain tissue were far too small to purify. The breakthrough came from the pancreas. Rare pancreatic tumours in a few patients with acromegaly were secreting a hormone that made their pituitaries overproduce growth hormone. In 1982 two groups at the Salk Institute, one under Roger Guillemin and one under Wylie Vale and Jean Rivier, sequenced it from that tumour tissue, and it proved identical to the hypothalamic hormone. Truncation studies soon showed that the front 29 residues, with an amide at the end, matched the activity of all 44.

How sermorelin acts

Most of the information sits at the amino end. The first few residues, tyrosine, alanine and aspartic acid, are needed for receptor activation, while the remainder forms a helix that holds the peptide in the binding site. That is also why the molecule is fragile: the activating end is exactly where DPP-4 cuts. Once bound, the receptor raises cyclic AMP in the somatotroph, and growth hormone is released in a brief pulse that follows the timing of the stimulus.

Human research on the fragment is older than most peptide literature. In a small 1992 clinical study, Corpas and colleagues gave GHRH 1-29 to older men for two weeks; at the higher of two doses, 24-hour growth hormone and IGF-1 rose to levels no longer different from those of young men. That paper is still cited as evidence that the ageing pituitary keeps a reserve which the right signal can call on.

Our view on what sermorelin acetate is for in a modern lab: it is the control every newer analogue implicitly measures itself against. Claims for Mod GRF, tesamorelin or the DAC conjugate are all claims of improvement over the native fragment, and the most convincing demonstration is to run the original in the same plate. The guide comparing the GHRH analogue family places all four side by side.

Buy Sermorelin Peptide Online in Australia, the Native GHRH Fragment

GHRH was isolated in 1982 as a 44 amino acid hormone, and structure work soon showed that the amidated 1-29 segment carried most of its activity. That synthetic fragment became sermorelin, which was registered in the United States as Geref and used to probe pituitary growth hormone reserve before it left the market. Its activity is brief, with a half-life of roughly 10 to 20 minutes, which is precisely what makes it useful as a baseline. Today it is a common laboratory reagent.

Buy sermorelin to give a lab the unmodified reference for the GHRH pathway, a way to characterise the receptor, measure pituitary secretory capacity in ageing models, or benchmark newer analogues against the original. It is sold here as a research reagent, not a medicine, within our GH peptide category.

Sermorelin in Australia: From Geref to a Schedule 4 Research Peptide

The vial holds 10 mg of sermorelin acetate as a lyophilised white powder, the acetate being the counter-ion left from purification rather than a second ingredient. Unlike most compounds in our growth hormone range, this one has been a finished medicine. Serono sold it in the United States as Geref, approved in 1997 for idiopathic growth hormone deficiency in children with growth failure, alongside a diagnostic version for testing pituitary reserve. EMD Serono told the FDA in 2008 that it was discontinuing the product, approvals were withdrawn in June 2009, and the FDA later found the withdrawal was not for reasons of safety or effectiveness.

Is sermorelin legal in Australia? It is a prescription-only substance with no product behind it. Sermorelin has its own Schedule 4 entry in the June 2026 Poisons Standard, still current in October 2026, and Appendix D, clause 5, which bars possession without authority, extends to growth hormone releasing hormones "including those separately specified in Schedule 4", wording that brings sermorelin in as well. Neither sermorelin nor Geref brings up a document in the TGA's product information search, and we found no current ARTG registration, so a prescriber here has no registered sermorelin product to write for.

On the sporting side, WADA's 2026 list names sermorelin as a GHRH analogue in class S2, alongside CJC-1295 and tesamorelin, and Sport Integrity Australia applies that prohibition at all times.

That gap between a known molecule and an empty pharmacy shelf is why sermorelin Australia supply comes from research suppliers. Our 10 mg vial is one such reagent: in stock in Australia, available to customers 18 or older, and intended for in vitro study rather than any use in humans or animals. Labs studying the full 44 residue hormone can compare it with the tesamorelin vials in three sizes.

Order Sermorelin Australia Supply for Sale in a 10 mg Vial

Order sermorelin in one fill, a 10 mg vial at $89, or $8.90 per mg. That sits a little above the stabilised CJC-1295 No DAC vial per milligram and below tesamorelin at the same fill, which is $99. Ten milligrams is the common research size for GHRH (1-29) peptides, and with a fragile native sequence, labs often mix only part of their stock at a time and keep the remaining vials sealed.

All sermorelin vials in one order come from a single lot wherever stock allows, so there is one certificate to file for the whole series. Purchases require the buyer to confirm they are 18 or older and to accept the research use terms.

Sermorelin keeps residues 1 to 29 of human GHRH without a single substitution, from the opening tyrosine to the amidated arginine. The sulphur in methionine 27 accounts for the S in its formula and is also its weak point, since that residue can oxidise. The acetate counter-ion does not change the active chain, and the identity data refer to the peptide itself.

Because sermorelin and Mod GRF (1-29) share a backbone, mass is the decisive check. A result near 3357.9 g/mol identifies sermorelin, while one near 3367.9 g/mol would point to the stabilised analogue. Look up your lot in the certificate archive and compare it with the guide to COA interpretation.

Order From Sermorelin Australia Shipping Near You and Store the Vial

Sermorelin is not kept at any counter or pickup point. The online store is the only way to buy, it serves labs from Perth to Hobart, and every order leaves from one domestic stock. Buyers of research peptides in Perth receive the very same lots as labs in the east. Payment cleared before 3pm on a business day means same-day dispatch, and timeframes appear on the delivery information page.

Two weaknesses shape handling. DPP-4 cuts the Ala2-Asp3 bond within minutes, and Met27 can oxidise. Reconstitute only when needed, running bacteriostatic water down the glass without agitation. Adding 2.5 mL to the 10 mg vial gives 4 mg/mL, and the concentration calculator works out any other volume.

Store the powder at -20 °C in the dark until use. The solution goes to 2 to 8 °C, and since the native sequence is less stable than its analogues, aliquoting it and finishing it well within 28 days is good practice. Label every aliquot with the lot number and mixing date so results trace back to the right certificate.

Other Names for Sermorelin

Sermorelin acetate is also listed as GRF (1-29) NH2, GHRH (1-29) amide, somatorelin fragment 1-29 or by its former US brand name, Geref. Some older papers call the parent hormone somatocrinin or growth hormone releasing factor, which is where the GRF abbreviation comes from.

Its receptor is GHRHR, a Gs-coupled receptor that raises cAMP inside somatotrophs. Downstream, the growth hormone it releases drives hepatic IGF-1, the marker most GH axis studies record.

Sermorelin, CJC-1295 No DAC or Ipamorelin, Which to Order

CJC-1295 No DAC, the Mod GRF (1-29) analogue, uses the same 29 residue frame with four substitutions that resist DPP-4, giving a half-life near 30 minutes against the 10 to 20 minutes reported for sermorelin. It costs $79 for 10 mg. Order sermorelin when the native sequence is the point of the study, and the stabilised version when a longer window matters more than fidelity to the natural hormone.

Ipamorelin works on a different receptor altogether, the ghrelin receptor GHS-R1a, and sells as a 10 mg vial for $59. A sermorelin ipamorelin CJC 1295 design covers both pituitary inputs with a native and a stabilised GHRH arm. Tesamorelin takes a third GHRH route, keeping all 44 residues behind an N-terminal cap, and sermorelin remains the least expensive way to keep an unmodified control in that comparison.
