Ipamorelin is a growth hormone secretagogue studied for its ability to stimulate growth hormone release through ghrelin receptor activity. It is commonly researched in recovery, body composition, sleep, and age-related hormone pathway studies.
Research Use Only. Not intended to diagnose, treat, cure, or prevent any disease.
For Research Purposes Only — Not for human or veterinary use. Statements not evaluated by the FDA.
Our Standards
Uncompromising Quality
We believe in complete transparency. Every batch is independently verified.
99% Purity Minimum
Every compound meets strict purity thresholds, verified by independent testing facilities.
COA Available
Batch-specific Certificates of Analysis are available for full transparency and verification.
Research Use Only
Strictly supplied for in-vitro laboratory research and analytical purposes only.
Full Transparency
Third-Party Tested by
Freedom Diagnostics
Every batch we offer is independently tested through Freedom Diagnostics, a third-party testing lab providing Certificates of Analysis for purity and identity verification.
Independent COA Verification
Customers can verify batch testing directly through Freedom Diagnostics' public COA lookup system using the accession or COA number listed with each product batch.
Purity + Identity Testing
Freedom Diagnostics reports testing using HPLC and LC-MS methods to help confirm both compound identity and purity.
Batch-Level Transparency
We believe every product should be backed by clear documentation, current batch data, and direct access to testing records.

Safety & Compliance
Research Do's & Don'ts
Guidelines for safe and compliant use of research compounds in laboratory settings.
Do's
- Store lyophilized compounds at 2–8°C (refrigerated) or -20°C for long-term stability.
- Use sterile bacteriostatic water or peptide-grade solvent for reconstitution.
- Follow all applicable local, state, and federal regulations governing research compound use.
- Review the Certificate of Analysis (COA) before beginning any experiment.
- Label all reconstituted vials with compound name, concentration, date, and initials.
- Dispose of needles, vials, and solvents according to your institution's biohazard protocols.
- Maintain a proper chain of custody and research log for all compounds used.
Don'ts
- Do not use these compounds for human consumption, self-administration, or veterinary use.
- Do not expose lyophilized compounds to repeated freeze-thaw cycles.
- Do not use compounds past their labeled expiration or beyond 28 days after reconstitution.
- Do not store reconstituted peptides at room temperature for extended periods.
- Do not share or resell research compounds outside of authorized research settings.
- Do not make medical claims or therapeutic representations about these compounds.
- Do not use without appropriate laboratory safety equipment and training.
