Independent vendor review
Review profile checked August 18, 2026 · Independently fact-checkedView Peptide Critic profile ↗
NextGen Peptides scored across our four rubric factors — COA practices (40%), reputation, transparency, and operations (20% each).
Weighted factor result: 7.8/10. The published score follows the weighted result after rounding.
Evidence summary
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.
What we reviewed, with the limits of that evidence kept explicit.
NextGen Peptides is the US storefront at singular ngpeptide.com. The current shop exposed 82 unique product URLs. The FAQ states US shipping, one to two business days of processing, standard delivery in three to five days, and card payment. Sales are final after shipment, with support handling incorrect, missing, or damaged orders. Do not transfer reviews from ngpeptides.com, nextgenpeptides.nl, NextGenPeps, or Nexxgen Peptides.
The public COA library is the strongest evidence. It lists 131 certificate entries, mainly from ILS Laboratories with some Janoshik records. The count includes duplicates and older batches, so it is not a count of 131 current products. PeptidePrices inspected ILS reports for BPC-157 10mg and Retatrutide 20mg. Both were batch-specific and included identity, purity, measured content, fentanyl screening, heavy metals, and multi-vial conformity results.
The exact-domain Trustpilot profile now states that it was removed for guideline violations. Peptide Critic separately shows 3/5 from seven reviews; that is community evidence, not Trustpilot. NextGen receives an 8/10 rating. The certificate program and US fulfillment are strong, while the external reputation record and public company information remain limited. The case-sensitive peptideprices10 code gives 10% off and was checkout-verified on August 25, 2026.
Buying details
The FAQ states 1–2 business days of processing and standard delivery in 3–5 days. Sales are final after shipping; contact support for incorrect, missing, or damaged orders.
Decision guide
A repeat buyer reported two-day shipping, competitive pricing, and batch-linked ILS Labs records that could be checked independently.
A second repeat buyer described fast delivery, straightforward card payment, and a separate batch number and COA link on each vial.
A critical reviewer reported that a locally tested Cagrilintide sample contained far less material than expected. This is a customer allegation, not a PeptidePrices laboratory result.
