Vitaliti Peptide

Every batch HPLC-verified ≥98%. Lot-traceable end to end.
Peptides are produced via solid-phase synthesis at a single GMP-aligned partner facility. Every production run is tied to a unique lot code from the first coupling step onward.
Independent third-party laboratories run HPLC purity analysis on every batch. Mass spec confirms peptide identity; a batch ships only if it clears ≥98% purity.
2–8°C, light-shielded, lot-segregated. Storage logs are reviewed weekly. Lyophilized vials remain shielded from light and humidity until they leave the facility. We do not consolidate batches under a single COA.
Discreet outer packaging. Every vial is labelled with its lot code and expiration date. Tracking is sent on label print.
Solid-phase synthesis produces a target peptide plus a long tail of byproducts — truncated sequences, deletion fragments, oxidised residues, residual coupling reagents. The 98% threshold caps these impurities at no more than 2% of the final product by mass. Anything below that, and the impurity profile becomes the dominant story. Anything above 98% and the marginal cost of additional purification stops buying meaningful identity. 98% is the industry-accepted ceiling where verified purity starts to mean something consistent across labs.
Every lot ships with an independent Certificate of Analysis on file: HPLC chromatogram, identity, the works. Email us to receive the COA for the exact lot you receive.
