What is Sermorelin?

Sermorelin reproduces the first 29 amino acids of human GHRH, the shortest segment of the native 44-amino-acid hormone reported to retain full receptor-binding activity. Its relatively short, unmodified structure gives it a much shorter circulating half-life than engineered long-acting GHRH analogues such as CJC-1295 with DAC.

How it is understood to work

Sermorelin binds GHRH receptors on pituitary somatotroph cells, prompting the synthesis and pulsatile release of endogenous growth hormone, which subsequently drives hepatic IGF-1 production. Because it stimulates the body’s own GH release rather than supplying GH directly, its activity remains subject to the normal somatostatin feedback loop that regulates the GH axis.

Research status

Sermorelin was previously marketed as an approved pharmaceutical for pediatric growth hormone deficiency evaluation before being discontinued commercially, giving it an established human pharmacology record; in current research settings it continues to be studied for the GH-IGF-1 axis, age-related decline in GH secretion, body composition and sleep architecture.

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

Specifications

Compound: Sermorelin
Also known as: Sermorelin Acetate, GHRH(1-29)
Class: Growth-hormone-releasing hormone analogue (29-amino-acid fragment)
Form: Lyophilized (freeze-dried) powder
Per vial: 5mg
Molecular formula: C₁₄₉H₂₄₆N₄₄O₄₂S
Molecular weight: 3357.9 g/mol
Stated purity: ≥99% (HPLC)
Appearance: White lyophilized powder

Handling & storage

Supplied as a lyophilized powder; store unopened vials at -20C protected from light, and once reconstituted with bacteriostatic water keep refrigerated at 2-8C for use within the study’s defined timeframe.

Concentration check: adding 2 ml of bacteriostatic water to one 5 mg vial gives 2.5 mg/ml. The Research Lab calculator in your dashboard works this out for any volume.

Questions

How does sermorelin differ from CJC-1295 with DAC?

Both are GHRH(1-29)-based analogues, but sermorelin lacks the Drug Affinity Complex modification, giving it a much shorter circulating half-life and making it useful for modeling short-pulse rather than sustained GHRH receptor stimulation.

Is sermorelin the same as growth hormone itself?

No. Sermorelin stimulates the pituitary to release the body’s own growth hormone rather than supplying GH directly, so its downstream effects remain subject to normal feedback regulation that direct GH administration bypasses.

How much Sermorelin is in this kit?

10 vials of 5 mg each, so 50 mg in total. The lab testing section above shows what the brand’s tested vial actually contained.
