Medium confidenceUpdated 6 days agoMethodology →

Puratek Peptides is a newer vendor with a public per-batch COA library verified to be from an accredited third-party CRO, which supports their credibility in purity testing. They offer a moderate catalog of 32 listings and accept credit card payments, but lack diverse payment options. Community engagement is limited, with minimal Reddit and YouTube presence, affecting their reputation and customer service scores. No FDA warnings have been noted, maintaining a clean regulatory record.

Pros & Cons

Pros

  • Aggressive single-vial GLP-1 pricing — Tirzepatide (PUR-2T) at $39.95 for 15mg ($2.66/mg) and $89.95 for 60mg ($1.50/mg), Retatrutide (PUR-3R) at $44.95 for 10mg ($4.50/mg) and $64.95 for 20mg ($3.25/mg), among the lowest tier we track at comparable sizes
  • Four-tier Retatrutide sizing (PUR-3R: 10 / 20 / 30 / 40 mg) — the 40mg vial is uncommon at any price tier
  • Three-tier Tirzepatide sizing (PUR-2T: 15 / 30 / 60 mg) — the 60mg single-vial is one of the largest single-vial Tirzepatide options we track
  • Two-tier NAD+ sizing (500 / 1000mg) and four hero blends (KLOW 80mg, BPC-157+TB-500 20mg, CJC+Ipamorelin 5/5mg + 10/10mg) alongside single-vial SKUs
  • Vendor states >99% purity verified by HPLC and Mass Spectrometry — a stricter purity claim than most peptide vendors publish
  • Customer coupon JON10 for 10% off at checkout

Cons

  • High out-of-stock rate at last scrape (~40% of catalog)
  • Several simple SKUs (TB-500, 5-Amino-1MQ) don't surface vial size in the product name
  • Third-party COA (Janoshik / Finnrick / equivalent) provider not surfaced on the public site — Puratek's stated >99% HPLC + Mass Spec purity is internally measured, not independently certified per batch
  • Lean ~30-SKU catalog — common compounds like Tesamorelin in multiple sizes, KPV multiple sizes, MOTS-c smaller sizes, and Cagrilintide larger sizes are not in stock
