GHRP-2 (Growth Hormone Secretagogue) – Pralmorelin / KP-102

Product Overview

GHRP-2 is a highly potent, synthetic hexapeptide growth hormone secretagogue (GHRP). Recognized for its robust efficacy, it is considered one of the most potent GH-releasing peptides on a per-microgram basis. It offers a balanced, optimized profile by providing massive GH stimulation with significantly less appetite stimulation than GHRP-6 and less cortisol elevation than Hexarelin. Uniquely, GHRP-2 has achieved formal clinical validation as an approved diagnostic agent in certain countries for assessing pituitary GH reserve, making it a premier compound for advanced endocrinology, somatopause, and body composition research.

Technical Specifications

• Molecular Formula: C45H55N9O6

• Molecular Weight: 817.97 g/mol

• CAS Number: 158861-67-7

• Sequence Profile: D-Ala-D-βNal-Ala-Trp-D-Phe-Lys-NH2

Mechanism of Action

GHRP-2 drives its powerful neuroendocrine effects through highly targeted receptor activation and downstream anabolic signaling:

• GHSR-1a Agonism: Binds with high affinity to the ghrelin receptor (GHSR-1a) on pituitary somatotroph cells, triggering an intense, rapid, and dose-dependent pulsatile release of growth hormone.

• Downstream IGF-1 Elevation: The robust GH pulse drives subsequent hepatic production of Insulin-like Growth Factor 1 (IGF-1), establishing an elevated plateau that mediates profound anabolic effects, including enhanced protein synthesis and nitrogen retention.

• Balanced Receptor Selectivity: Provides significant GH release while minimizing off-target hormonal effects. It triggers far less ghrelin-mimetic (appetite-stimulating) signaling than GHRP-6 and limits the rapid tachyphylaxis (desensitization) and cortisol spikes associated with Hexarelin.

• Synergistic Amplification: When co-administered with a GHRH analog (such as CJC-1295 or Sermorelin), it activates complementary pituitary pathways, overcoming negative feedback inhibition to yield exponentially greater GH release than either compound alone.
