Why source Ipamorelin 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Quality control across the research-peptide industry is inconsistent, and many suppliers do not publish third-party testing for their products.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.

What is Ipamorelin?
Ipamorelin is a synthetic pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2) classified as a selective growth hormone secretagogue (GHS). It was characterized in the literature as the first selective growth hormone secretagogue.
Mechanistically, it acts as a ghrelin mimetic, binding the growth hormone secretagogue receptor (GHS-R1a) — the receptor for the endogenous peptide ghrelin, expressed in the pituitary and hypothalamus. It is studied as a research chemical to investigate GHS-R1a signaling in experimental models. It is not a SARM.
Ipamorelin 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
Ipamorelin 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
As a growth hormone secretagogue and ghrelin receptor agonist, Ipamorelin is 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, Ipamorelin is not a controlled substance and may be legally purchased and possessed for laboratory research use.
