GHRP-2 - Generic Peptides

Buy GHRP-2 5 and 10 mg vials by Generic Peptides at XSteroids. GHRP-2, also known as pralmorelin, is a short synthetic peptide that pushes the pituitary to release growth hormone of its own. The vial arrives as lyophilized powder, packed for the laboratory. Below you will find the peptide itself, its action at the ghrelin receptor, what human studies measured, how to mix each vial and read it on a U-100 syringe, plus stacking, storage and legal questions.

Pralmorelin, the same molecule, is licensed in Japan as a diagnostic test and for nothing else. The powder here is bench material, and no quantity below has been approved as a human dose.

What GHRP-2 by Generic Peptides Is and What You Are Buying

GHRP-2 is a short peptide built from unnatural D-amino acids, with the sequence D-Ala-D-(2-naphthyl)-Ala-Ala-Trp-D-Phe-Lys-NH2 and a molecular mass of about 817.992 g/mol. It belongs to the growth hormone releasing peptide family, which started as analogues of met-enkephalin, and it carries the international name pralmorelin. The codes KP-102 and GPA-748 refer to the same molecule.

One glass vial arrives per order, filled with white lyophilized powder, at either 5 mg or 10 mg. Water for mixing is not supplied with it. No excipient list is published for these vials and no independent potency test exists, so the page repeats only what the supplier prints on the label.

How GHRP-2 Works at the Ghrelin Receptor

The receptor GHRP-2 binds is the ghrelin receptor, known too as the growth hormone secretagogue receptor, or GHSR. GHRP-2 is an agonist there, which makes it a different tool from a GHRH analogue: the GHRH receptor and the ghrelin receptor are separate proteins, and the two peptides have no sequence relationship. Where GHRH tells the pituitary that releasing hormone is present, GHRP-2 mimics the hunger signal ghrelin and fires the same cell from a second input. The same receptor is also found in the hypothalamus, which helps explain why one peptide produces both a hormone signal and an appetite signal in the same study.

Pharmacokinetics have been measured in humans. After intravenous administration the half-life of pralmorelin is between about 25.2 and 41.4 minutes, so it is a short-acting peptide. That short window is why research protocols use frequent, small injections rather than one large one, often timed before sleep when natural growth hormone output peaks. Its hormonal footprint is wider than that of ipamorelin: GHRP-2 stimulates ACTH and cortisol as well, a difference the class reviews highlight, and one that any plan monitoring stress hormones has to take into account.

What to Expect from GHRP-2 Research

Human work reports that an acute dose significantly raises plasma growth hormone, and that the same dose reliably increases hunger and food intake. Those two effects are the best-documented outcomes in the literature, and they come from small controlled studies, not from large trials. The studies were short and enrolled few participants, so effect sizes should be read as directions rather than fixed numbers.

Development adds an important caution. GHRP-2 was studied for growth hormone deficiency and short stature, reached phase II, and never reached the market for those indications; the source literature ties that to a growth hormone response in deficient patients that was lower than expected. In Japan the compound is registered only as a single-dose diagnostic test for growth hormone deficiency, administered under medical supervision, and sold as GHRP Kaken 100. That is a diagnostic, not a treatment, and it is not a model for anything on this page. Claims about muscle gain or fat loss are outside what the studies measured.

Mixing 5 mg and 10 mg Vials

Start with the fact that a U-100 insulin barrel numbers one unit for each 0.01 ml, so 10 units equals a 0.1 ml draw. Adding 2 ml to the 5 mg vial puts the mix at 2.5 mg per ml, and a draw of 0.1 ml delivers 250 mcg. Put the same 2 ml into the 10 mg vial and the mix reaches 5 mg per ml, with 0.1 ml carrying 500 mcg. Give that 10 mg vial 5 ml instead for 2 mg per ml, and 0.1 ml then carries 200 mcg.

Because the half-life is under an hour, a single mixed vial supports many sessions, so label it with its concentration and keep it cold between draws. Swirl gently rather than shaking, and do not refreeze a solution that has already been thawed.

Stacking GHRP-2 With Other Generic Peptides

GHRP-2 is normally researched next to a GHRH analogue, since the two receptors act on the same somatotroph cell from different directions. CJC-1295 (no DAC) 2, 5 and 10 mg supplies the short GHRH signal, CJC-1295 DAC 2, 5 and 10 mg the long-acting one, and Sermorelin 2, 5 and 10 mg stands as the older generation of analogue.

Among the secretagogues, GHRP-6 5 and 10 mg is the nearest relative, Ipamorelin 2, 5 and 10 mg trades breadth for selectivity, while Hexarelin 2 and 5 mg carries the strongest potency in the group. The direct hormone option is Somatropin 100 to 200 IU. No pairing of these products is an approved combination.

Recovery Markers for GHRP-2 Research

GHRP-2 sits upstream of the testosterone axis, so natural testosterone production continues unaffected and post-cycle therapy has no place in the plan. The readouts the studies used are growth hormone itself, IGF-1, and because of the cortisol effect, sometimes ACTH and cortisol. Insulin and glucose handling are worth noting in any plan that stacks secretagogues, since growth hormone shifts them. Body weight and appetite are worth logging too, because food intake is one of the endpoints the studies actually measured.

GHRP-2 Side Effects and Legal Status

Reported effects include a rise in appetite, irritation at the injection site, water retention, aching joints and higher cortisol and prolactin markers. Because hunger increases reliably, an appetite change counts as an expected observation rather than a surprise. Secretagogues of this class are barred in sport at all times under WADA class S2, and pralmorelin has no approved use outside the Japanese diagnostic setting.

Storage of GHRP-2

Dry powder belongs at 2 to 8 C away from light and must not go into a freezer before mixing. After water is added, store the vial at 2 to 8 C and finish it within 28 to 30 days. A solution that becomes cloudy or carries particles is discarded, and a thawed solution is never refrozen.
