Product information
Sermorelin, also called GRF (1-29) or GHRH (1-29), is a synthetic chain of 29 amino acids. It is an exact copy of the first 29 building blocks of GHRH, the body's own hormone of 44 amino acids that prompts the pituitary gland to release growth hormone. Those first 29 building blocks are the part the GHRH receptor recognises; the rest of the chain is not needed for that.
This makes sermorelin the starting point of the entire GHRH family. CJC-1295 no DAC (Modified GRF 1-29) is the same chain with four swapped building blocks; tesamorelin is the full chain of 44 amino acids with an extra group at the start. Sermorelin is the unedited version: the same key as GHRH, shortened to what the receptor needs.
Because the chain has not been modified, enzymes break sermorelin down just as quickly as the body's own GHRH. In the literature, the substance is therefore known as a short-acting GHRH analogue. There it is usually called sermorelin acetate; under the brand name Geref, that acetate salt was previously registered as a medicine and later withdrawn from the market.
Related products in our assortment are CJC-1295 no DAC, Tesamorelin and Ipamorelin, which acts on a different receptor. How to dissolve the powder with bacteriostatic water is explained in our reconstitution and storage guide. The full range is listed under Muscle building & performance.

Frequently Asked Questions
What is sermorelin?
A synthetic chain of 29 amino acids, also known as GRF (1-29). It is an exact copy of the first part of GHRH and fits the same receptor in the pituitary gland.
What is the difference between sermorelin and CJC-1295 no DAC?
Both consist of the same 29 building blocks. In CJC-1295 no DAC, four of them have been replaced (at positions 2, 8, 15 and 27), which makes that chain less susceptible to breakdown by enzymes. Sermorelin is the unmodified chain.
What is the difference between sermorelin and tesamorelin?
Tesamorelin contains all 44 amino acids of GHRH plus a trans-3-hexenoyl group at the start of the chain. Sermorelin contains only the first 29, without an extra group.
Is sermorelin an approved medicine?
As Geref, sermorelin acetate was previously registered in a few countries; that product has been withdrawn from the market. What we supply is intended solely for laboratory research.
What do you dissolve sermorelin in?
With sterile bacteriostatic water. It is included free with every vial. Let the liquid run down the wall of the vial and swirl gently rather than shaking.
How do you store sermorelin?
Unopened, store in a cool, dry, and dark place at 2 to 8 °C. For longer storage, -20 °C is suitable, only in powder form. After dissolving, store the vial refrigerated; the quality of the peptide deteriorates from approximately 30 days.
