Research-Grade Peptides
Consistent quality, transparent testing, and fast, reliable fulfillment on every order — the standard researchers expect.
Four independent analytical checks are completed before a compound is released — and the results are documented on the Certificate of Analysis for that lot.
We've moved to bulk sourcing across the entire catalog — and we're handing the savings straight to you. Same US-sourced material, same COA on every batch, lower pricing sitewide.
Registered businesses with a valid EIN can open a K4 Elite wholesale account. Pricing runs on five tiers, and every order finds its own tier — the larger the order, the lower every price on it becomes. Nothing to track and nothing to renegotiate: order big one month and small the next, and each order simply prices where it lands. Quoted by the box of 10, splittable into half boxes of 5 so you can mix compounds. Applications are reviewed by hand, usually within one business day.
Every order prices itself. Your tier is set by the order in front of you — no application for a tier, no monthly minimum to keep hitting, no code to remember. Approved accounts see their tier pricing the moment they sign in. Volume beyond the Distributor tier is agreed individually — email wholesale@k4elite.com or text (318) 517-3831. All products are supplied for in-vitro laboratory research use only.
