GHRP-1 (5mg/10mg)

What is GHRP-1?

GHRP-1 is the original peptidyl growth hormone secretagogue from which the entire GHRP family was developed.

Listed vial contents: 5mg / 10mg. These are supplied quantities, not administration doses. Current pricing and availability are shown in the strength selector.

What mechanisms are being studied?

GHRP-1 is a synthetic hexapeptide (Ala-His-D-βNal-Ala-Trp-D-Phe-Lys-NH2) and the founding member of the growth-hormone-releasing peptide family. It binds the ghrelin receptor (GHS-R1a) on pituitary somatotrophs and hypothalamic neurons, triggering pulsatile GH release. It synergizes additively with GHRH-class peptides through a complementary signaling pathway.

What are the research questions?

• GH secretagogue research: The reference compound for early GHRP pharmacology studies.
• Hypothalamic-pituitary axis assessment: Used in diagnostic protocols evaluating GH reserve.
• Comparative pharmacology: Frequently used as a reference comparator in studies characterizing GHRP-2, GHRP-6, ipamorelin, and hexarelin.

What does the published work describe?

Bowers CY et al. (Endocrinology 1984, 1990) — established the GHRP class and demonstrated robust dose-dependent GH release in humans. Minimal effect on prolactin, cortisol, or ACTH compared with GHRP-2/6.

What are the limits of this evidence?

The research described concerns the cited experimental materials and models, not proof that this supplied vial is a treatment. Cell or animal findings do not establish human benefits. Clinical findings, where cited, apply to the tested formulation and population; they do not validate this research product for human use.

How should I check lot documentation?

Match the product, strength and lot to an original analysis document. Literature describes experimental findings; it does not verify the contents of this inventory. A report is evidence only for the product, strength and lot it names.

How is GHRP-1 handled in the lab?

Plan a GHRP-1 stock solution from the sequence, the listed molecular weight (956.13 g/mol) and, when reported for the same lot, net peptide content. Test-dissolve a small portion first, store the powder sealed, cold and dry, and split solutions into single-use aliquots. These are laboratory handling notes, not administration guidance.

• Peptide solubility: choosing a lab solvent
• Stock solution molarity and concentration math
• Lyophilized storage, aliquoting and freeze-thaw
• Fmoc vs Boc synthesis and the impurities they leave
