What we can confirm, and the honest caveat

Confirmed
Names Janoshik Analytical and Vanguard Laboratory; certificates resolve on the lab's own domain (verify.janoshik.com). Product pages list dated batch codes for previous certificates, no account required. Legal entity, Tampa, FL address, EIN and sales-tax number published: Plainview Commerce LLC. Full basket with sized pricing, stable across reads.
The honest caveat
Small review base (65 on Trustpilot, 26 Sep 2026). Measured net content could not be read from the certificate images. The legal entity name appears on the refund policy but not the About page. GLP products sold under house codes PG-1SG / PG-2TZ / PG-3RT.

This page answers the trust question. Prices with the code, the certificate we opened (lot, purity, measured mass), and where Peptide Giants ranks by compound are in the Peptide Giants review.

What Reddit says
The Reddit results for Peptide Giants are mostly marketing: an 'honest review' and a 'top 4 legit companies' post in r/technewscomu (not a peptide community), and promo-code drops in unrelated subreddits. The one organic mention is a DSIP thread where a user considered ordering from them. Treat the 'review' posts as ads. The threads, labelled →

Check it yourself in ten minutes

  1. Open the certificate we checked on Janoshik Analytical's own system and compare the lot to the vial you would receive — a certificate that only exists on the vendor's server proves nothing.
  2. Read the one-star reviews on Trustpilot, not the average — the themes there are what you would be living with if an order goes wrong.
  3. Find the company name and street address on the vendor's terms or contact page. We found them (above); confirm they are still printed.
  4. Pay by card where it is offered. A card charge can be disputed; crypto, Zelle and ACH cannot.

Our vendor-vetting checklist and COA reading guide walk through each step for any vendor.
