GHRP-2Research-Grade Peptide · Lab-Verified Purity
GHRP-2 is the most potent of the classic first-generation growth-hormone- releasing peptides — the "OG" of this research space. It works by mimicking ghrelin (your body's hunger hormone) at its receptor, which is what drives the strong GH- release signal. That potency comes with a caveat: unlike Ipamorelin, it does bump cortisol and hunger a bit alongside GH.

GHRP-2 — Product Overview
GHRP-2 is the most potent of the classic first-generation growth-hormone- releasing peptides — the "OG" of this research space. It works by mimicking ghrelin (your body's hunger hormone) at its receptor, which is what drives the strong GH- release signal. That potency comes with a caveat: unlike Ipamorelin, it does bump cortisol and hunger a bit alongside GH.
GHRP-2 — Molecular Characteristics & Vial Specifications
ProSource Labs supplies GHRP-2 in the following available vial sizes: 10mg. Each GHRP-2 vial contains pure lyophilized peptide — no fillers, no bulking agents. Product SKU references: GHRP2-10MV.
- Strongest Classic GHRP: The most potent of the first-generation growth-hormone releasers
- Ghrelin Mimic: Activates the same receptor as your natural hunger hormone
- Hunger Bump: Does mildly stimulate appetite — not appetite-neutral like Ipamorelin
- Also Called: Known as 'Pralmorelin' in older diagnostic-medicine literature
Batches are characterized by ESI mass spectrometry to confirm molecular weight against the theoretical value, with amino-acid sequence confirmation on selected QA lots. Peptide content assay distinguishes net peptide mass from residual counter-ion salt.
GHRP-2 — Laboratory Handling & Storage
Lyophilized GHRP-2 vials should be stored at -20°C (or colder) in a laboratory freezer, inside the sealed factory container. Minimize warm-up cycles — move only the specific vial needed for a given experiment out of frozen storage at a time.
All laboratory handling of GHRP-2 should follow the receiving institution's SOPs and applicable peer-reviewed protocols relevant to the researcher's specific experimental question. ProSource Labs does not publish end-user preparation or usage instructions.
GHRP-2 — Third-Party Analytical Testing
Every batch of GHRP-2 released by ProSource Labs undergoes independent reverse-phase High Performance Liquid Chromatography (HPLC) — the industry-standard analytical method for this class of research compound. Target chromatographic purity is typically ≥ 99%.
Additional characterization may include ESI mass spectrometry for molecular weight confirmation, Karl Fischer titration for residual moisture, and appearance/solubility inspection. A batch-specific Certificate of Analysis (COA) is available on request through customer support after purchase.
GHRP-2 — Quality Assurance Process
Each production lot of GHRP-2 is quarantined pending analytical release, tested against documented purity, identity, and moisture acceptance criteria, and only released to sellable inventory after passing every QA checkpoint. Batches that fail any single criterion are quarantined and never reach customer-facing inventory.
If a vial of GHRP-2 you received from ProSource Labs ever fails your own institution's incoming QA testing, contact customer support at support@prosourcelabs.org — we retain samples of every batch for cross-verification.
GHRP-2 — Typical Research Application
Research work on ghrelin-receptor biology, GH pulse magnitude, and appetite/food-intake brain circuits. Used in Japanese diagnostic literature as a probe for GH-deficient patient identification.
GHRP-2 — Packaging & Fast Southern California Shipping
GHRP-2 vials ship in tamper-evident, moisture-resistant, cold-chain-friendly outer packaging from our Southern California distribution facility for fast US domestic delivery — typically 2-4 business days coast-to-coast, with expedited options available at checkout.
Every GHRP-2 shipment is discreet — the outer packaging carries no product-specific branding or direct reference to the compound name inside, protecting researcher privacy. Tracking numbers are emailed automatically. For institutional or high-volume orders, dedicated wholesale pricing is available through the wholesale portal.
