Storage & handling
Peptides are photo- and temperature-sensitive; handle per standard laboratory practice.
- Lyophilized storage: Keep the sealed vial cool, dry, and protected from light. For longer-term storage, freezing is standard practice for lyophilized peptides.
- After reconstitution: Refrigerate (approximately 2–8 °C) and follow your institution’s SOPs for aliquoting, handling, and disposal. Avoid repeated freeze–thaw cycles.
- Diluent not included: A suitable laboratory diluent and reconstitution supplies are not provided with this product.
- UV-resistant glass vial to help protect photo-labile peptides during storage.
- Tamper-evident seal to support chain-of-custody and inventory controls.
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Quality control across the research-peptide industry is inconsistent, and many suppliers do not publish third-party testing for their products.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.
Verified by MZ Biolabs (Tucson, AZ), an accredited US laboratory, via HPLC and mass spectrometry, with batch-linked COAs.
Freeze-dried into sterile, UV-resistant glass vials and packaged in the USA.
Supports chain-of-custody, label transparency, and batch-linked traceability.
Transparent business, standard payment methods, no misrepresentation.
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.
Important regulatory information
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.
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).
In the United States, Ipamorelin is not a controlled substance and may be legally purchased and possessed for laboratory research use.
Sports Technology Labs are chemical suppliers, not medical providers. We do not condone or encourage consumer use of research compounds.
