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
