Key facts
Pros
- Independent, per-batch Janoshik COAs (HPLC purity plus LC-MS identity) with a public on-site COA archive linked from product pages and real batch-specific verify.janoshik.com report links
- Named UK limited company (Ascend Peptides UK Ltd, Companies House 17036171, London office) with explicit research-use-only labeling, broad payment options (Stripe card, PayPal, bank transfer, Bitcoin 10% discount), and fast free Royal Mail same/next-day UK shipping over GBP 50
Cons
- Very young (company incorporated Feb 2026, domain only months old) with an extremely thin review sample (~6 Trustpilot reviews), and the Janoshik certificate could not be personally opened this session (Cloudflare-gated), so the raw HPLC figure is unconfirmed
