Overview

Bench Grade Peptides, operated by Bench Grade Peptides LLC, sells lyophilized research peptides, named blends and bacteriostatic water at benchgradepeptides.com. Its own first-order code takes 15% off a first order of $200 or more, as the site banner showed on November 6, 2026. Bench Grade states that its peptides are synthesized, filled and tested in the United States by partner manufacturers, from starting materials sourced domestically and internationally.

Bench Grade has issued Prof. Peptide its own code. Bench Grade's affiliate page, read on November 6, 2026, says an affiliate's code “takes an extra 10% off a first order, on top of the current deal”. Its promotion terms (effective September 14, 2026) say the automatic discounts compete with promo codes and referral discounts, so an order receives whichever is larger, never a combination. Those are Bench Grade's own two statements; Prof. Peptide has not tested the code at checkout, because the store's cart is closed to automated readers. The store's own first-order code (15% off $200 or more) is the larger of the two first-order offers, so “See offer” leads with it.

Bench Grade Peptides is based in Dover, Delaware and ships its orders from Florida. Bench Grade Peptides states that Synthesized, filled and tested in the United States, from starting materials sourced domestically and internationally.
