Description
Sermorelin 2mg is a 2mg vial of Sermorelin, a GHRH analog, supplied by Blue Sky Peptide as freeze-dried powder. This batch tested at 99.16% purity. It’s for in-vitro and lab research only.
What is Sermorelin?
Sermorelin is GHRH(1-29), the first 29 amino acids of growth hormone releasing hormone. It’s the shortest fully active piece of GHRH.
It was FDA-approved as Geref for pediatric GH deficiency and later withdrawn for commercial reasons.
Sermorelin mechanism of action
Sermorelin is the shortest piece of GHRH that still works. It binds the GHRH receptor on the pituitary and triggers growth hormone release.
Because it works through the body’s own GH control, the pituitary’s feedback loops stay intact. The trade-off is a very short half-life.

What the research says about Sermorelin
Clinical work in the 1990s studied it in children with GH deficiency and in older adults.
Its half-life is only minutes.

How Sermorelin compares
Here’s how Sermorelin 2mg fits among related compounds. Sermorelin is the unmodified first 29 amino acids of GHRH, broken down within minutes. By comparison:
- CJC-1295 No DAC is a stabilized GHRH(1-29) with a half-life of about 30 minutes, giving short, natural-looking pulses
- CJC-1295 DAC binds albumin and lasts about a week, giving a raised GH baseline instead of short pulses
- Tesamorelin is full-length GHRH with a fatty acid cap, the only GHRH analog currently approved as a drug in the US
These are all GHRH analogs, acting on the same receptor. The real difference is how long each one lasts, which decides whether you get short pulses or a raised baseline. See them all on our growth hormone peptides page.
How to reconstitute Sermorelin 2mg
Concentration is the amount in the vial divided by the liquid you add. With 2mg in this vial:
- 1mL of water gives 2mg/mL
- 2mL of water gives 1mg/mL
Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later.
Most labs use sterile bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll the vial gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.
Sermorelin 2mg storage and shelf life
The dry powder keeps best cold. A freezer at -20°C is ideal for long-term storage, and a fridge works for a few weeks. After reconstitution, store it in the fridge and finish it within roughly four weeks.
Vials are small and easy to knock over or misplace. Our vial storage case and hard storage box each hold ten, so a whole study’s worth stays together.
Sermorelin 2mg purity and testing
Purity for this batch of Sermorelin 2mg came back at 99.16% by HPLC and mass spectrometry. That’s the figure for the batch currently in stock.
Note the batch number on the label when the vial arrives. That’s what the certificate of analysis is filed under, and we’ll send you a copy on request.
If a result looks off, check the batch number first, then your handling notes. Most problems with Sermorelin come from storage or mixing, not the material.
