Biotech peptides GHRP-2: the stronger ghrelin agonist

Biotech peptides GHRP-2 comes in 5mg and 10mg vials and in three blends. Here is what sets it apart from ipamorelin and GHRP-6.

What is biotech peptides GHRP-2?

Biotech peptides GHRP-2 is growth hormone releasing peptide 2, a synthetic hexapeptide (D-Ala-D-2Nal-Ala-Trp-D-Phe-Lys-NH2) that activates the ghrelin receptor, GHS-R1a. It’s also known as pralmorelin, and in Japan it has been used as a diagnostic agent to test growth hormone reserve.

We stock GHRP-2 5mg and GHRP-2 10mg, both freeze-dried and made in the USA, with lot paperwork in the product gallery.

GHRP-2 vs ipamorelin and GHRP-6

All three act on the same receptor. Human studies found GHRP-2 gives one of the largest GH responses in the class, with small rises in cortisol and prolactin. Ipamorelin gives a smaller GH pulse with almost no effect on those hormones, and GHRP-6 is known for raising hunger as well.

So GHRP-2 suits studies that want the biggest response, while ipamorelin suits studies that need a clean signal. The research is indexed on PubMed.

GHRP-2 blends

Pairing GHRP-2 with a GHRH analog gives a larger GH pulse than either alone. We sell it premixed as the CJC-1295 GHRP-2 blend, the Mod GRF 1-29 GHRP-2 blend and a three-way blend with ipamorelin. Our CJC-1295 guide explains the GHRH side.

How much GHRP-2 to order

Add up the total amount each group needs across every time point, then divide by the amount in one vial and round up. Add one spare vial for a repeat run or a lost dose. Buying everything at once keeps the whole study on one lot, which removes a variable you’d otherwise have to report. Keep unmixed vials frozen and reconstitute one at a time.

Designing a study around GHRP-2

Studies with GHRP-2 usually measure GH at several time points in the first hour, since the response peaks quickly. Because GHRP-2 also nudges cortisol and prolactin, it’s worth measuring those too if your question is about selectivity. Running ipamorelin as a comparator in a parallel group makes the difference easy to see.

Storing biotech peptides GHRP-2

Freeze the sealed vial at -20°C when it arrives. Reconstitute it with sterile bacteriostatic water, keep the solution at 2 to 8°C and use it within about four weeks. The product page for GHRP-2 10mg lists the concentration you get with 1mL, 2mL or 3mL of water.
