Frequently Asked Questions
Are your compounds third-party tested?
Yes — without exception. Every single batch is assayed by an ISO-17025 accredited independent laboratory before release. We test for purity, identity, sterility, endotoxins, and heavy-metal contamination.
What does the purity percentage actually mean?
Our purity figures come from HPLC (high-performance liquid chromatography) analysis, which measures the percentage of the target compound relative to impurities. A figure of 99.8% means 99.8% of the material is the verified peptide, with the remainder being trace synthesis byproducts well within pharmaceutical thresholds.
How are orders shipped and stored?
All lyophilized peptides are stored in temperature-controlled GMP facilities and shipped same-day when ordered before 2pm EST. Orders over $100 receive free insulated shipping. We include reconstitution and storage guidance with every order.
Do you provide reconstitution and dosing guidance?
Yes. Every order includes precise reconstitution instructions, bacteriostatic water ratios, and storage protocols.
Is there a satisfaction or quality guarantee?
If any product arrives compromised, or a COA cannot be matched to your batch, we replace it or refund it — no questions asked.
