What the price already covers

A certificate of analysis for the exact lot in the box, not a specimen from a previous one.
Purity by reversed-phase HPLC and identity by mass spectrometry, on every lot.
A second assay at an independent laboratory, drawn from the lot that ships to you, at our cost.
Net peptide content measured rather than assumed, so the reconstitution maths is right.
The manufacturing facility named on the record, and named again if we stop buying from it.

Free shipping over $99, out the door by 2pm ET, and 60 days to send an unopened vial back for a full refund.
