Add two eligible single-peptide vials. When your cart hits $80+, a third vial slot unlocks at checkout, choose any vial $80 or under, and it’s added at no charge. No discount code, no manual step.
All individual peptide vials qualify. Pre-built bundles and accessories are excluded. If it’s a standalone vial on the catalog page, it’s eligible.
Every order includes a batch number traceable to a public COA on our website. Third-party HPLC and endotoxin results are available before you order, not just after.
