How do I reconstitute this peptide?
Use bacteriostatic water (BAC) at a 1–2 mL volume per vial. Inject solvent slowly down the vial wall, swirl gently — never shake. Refrigerate after reconstitution and use within 30 days.
How should I store this product?
Lyophilized: 36–46°F (refrigerated) for up to 24 months. Reconstituted: keep refrigerated and protect from light; use within 30 days. Avoid repeated freeze-thaw cycles.
What is the typical research dosing range?
For research use only. Published in vitro / animal studies typically use sub-milligram dosing scaled to subject mass. Consult primary literature for your specific protocol; we do not provide human dosing guidance.
