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 fast do you ship and is cold shipping required?
Orders are processed within 0-2 business days. Standard shipping takes 3-5 business days from fulfillment. Every order includes free shipment protection. Lyophilized peptides don't require cold shipping—they're stable at room temperature. All orders ship in discreet, unlabeled packaging.
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.
