Why source GHRP-6 from Sports Technology Labs
Quality control across the research-peptide industry is inconsistent, and many suppliers do not publish third-party testing for their products. Independent verification of identity and purity is essential for reproducible research.
Third-party tested & certified
Verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry, with batch-linked COAs.
Lyophilized & packaged in America
Freeze-dried into sterile, UV-resistant glass vials and packaged in the USA.
Tamper-evident packaging
Supports chain-of-custody, label transparency, and batch-linked traceability.
60-day money-back guarantee

What is GHRP-6?
GHRP-6 (growth hormone-releasing peptide-6) is a synthetic hexapeptide with the sequence His-D-Trp-Ala-Trp-D-Phe-Lys-NH2. It belongs to the growth hormone-releasing peptide (GHRP) family and acts as an agonist of the growth hormone secretagogue receptor (GHS-R1a), the receptor for the endogenous peptide ghrelin.
Structural studies of the ghrelin receptor indicate that GHRP-6 binds and activates GHS-R1a through interactions distinct from those of acyl-ghrelin. It is used as a research chemical to investigate GHS-R1a signaling in experimental models.
GHRP-6 is an experimental research chemical, supplied strictly for laboratory research. Sports Technology Labs makes no claims regarding its effects, and nothing in this listing should be interpreted as describing outcomes in humans or animals.
Regulatory & compliance status
Important regulatory information
Not approved for human use
GHRP-6 is an investigational research peptide. It is not approved by the FDA and is not a drug, food, dietary supplement, or cosmetic. Marketing it for human use is unlawful.
WADA-prohibited
Growth hormone-releasing peptides (GHRPs), including GHRP-6, are prohibited by the World Anti-Doping Agency at all times under S2 (Peptide Hormones, Growth Factors, Related Substances and Mimetics) (ref. 3).
Legal status for research
In the United States, GHRP-6 is not a controlled substance and may be legally purchased and possessed for laboratory research use. Other jurisdictions may regulate it differently.
