NextGen Peptides

NextGen Peptides is a US-only research-peptide storefront founded in 2022. It offers a broad catalog of individual vials, multiple-size products, and ten-vial packs, with FedEx 2-Day Air for residential orders and a published processing target of 36 hours for most orders. The current comparison includes every standard vial or pack that could be matched to a supported compound and an exact quantity; cosmetics, apparel, bacteriostatic water, oral formulations, raw powder, and blends without a reliable comparison match are excluded.

The public COA library is the strongest evidence. It lists 97 certificates and identifies labs including ILS Laboratories, Janoshik, Freedom Diagnostics, and BioInfinity. PeptidePrices inspected current ILS reports for BPC-157 10mg and Retatrutide 20mg. Both were batch-specific and independently verifiable and included identity, purity, measured content, fentanyl screening, heavy metals, and multi-vial conformity results. Use the date printed inside each PDF because some library date labels appear in an ambiguous day/month order.

NextGen receives an 8/10 rating. The deep, multi-panel certificate program and straightforward US fulfillment are strong. The score is held back by a limited independent reputation footprint and sparse public company information, not by its affiliate program.
