This compound has been the subject of peer-reviewed preclinical research investigating its biological activity and mechanism of action. Published studies are available through PubMed and other scientific databases. True Peptides does not make any claims regarding therapeutic efficacy or suitability for human use. All research applications should be conducted in accordance with applicable institutional and regulatory guidelines.

Store lyophilized powder refrigerated at 2°C – 8°C (36°F – 46°F), protected from light and moisture.

Reconstitution: Add bacteriostatic water (BAC water) slowly to the vial. Do not shake — gently swirl until fully dissolved. For compounds requiring an acidic solvent, use 0.6% acetic acid solution.

Once reconstituted, store at 2°C – 8°C and use within 28 days. For longer-term storage of reconstituted solution, freeze at -20°C.

Avoid repeated freeze-thaw cycles. Handle with standard laboratory precautions.

Each batch of True Peptides research compounds is independently tested by an accredited third-party laboratory. The Certificate of Analysis (COA) confirms identity, purity (≥99% by HPLC), and absence of contaminants.
