COA & lab verification
NextGen publishes a searchable library of 97 certificates with product and batch references and downloadable reports from named laboratories. PeptidePrices inspected current ILS Laboratories reports for BPC-157 10mg batch BPC10-08 and Retatrutide 20mg batch RT20-09. The ISO/IEC 17025-accredited reports confirmed identity, 99.90% and 99.99% purity, 10.68mg and 20.87mg measured content, fentanyl screening, heavy metals, and four-vial conformity data. The library states that older pre-March 2026 records may need to be requested, and some on-page dates render ambiguously; use the date printed inside the PDF and match the exact batch received. Affiliate status does not influence the rating.
Our verdict on NextGen Peptides
Promising and COA-strong. NextGen publishes unusually detailed, batch-specific named-lab reports, and the two sampled ILS certificates included both measured content and broader screening beyond purity.
Match the PDF to the exact batch, use a reversible payment method when available, and review the shipping-protection terms. The remaining reasons for caution are the short independent track record and limited public company disclosure.
More about 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. Code JACKRYAN currently provides 10% off; a request to rename it PEPTIDEPRICES is awaiting vendor confirmation.
