Pros & Cons

Pros

Janoshik Analytical (community-independent peptide testing) on every batch with a public per-batch verification key system — customers can paste any batch's key directly into janoshik.com/verify to pull the original signed HPLC report. Strongest verifiability tier we've seen across the directory
Recent BPC-157 5mg COA: 99.034% purity by Janoshik
Aggressive Retatrutide (GLP-3 RT) tiering — 10/20/30/40mg single vials at competitive $/mg, including a rare 40mg single-vial size
Pre-mixed hero blends — GLOW (70mg, GHK-Cu/BPC-157/TB-500) + a multi-vial 'GLOW + GHK-Cu Research Bundle' that adds a second 50mg GHK vial alongside the standard GLOW
Free US shipping over $200
Customer code 'STACKEDHQ' applies 10% off at checkout

Cons

Smallest single-vial catalog in our directory at 10 peptide SKUs — covers the staple injectables but no Tirzepatide, no Semaglutide, no bioregulators (Vilon / Vesugen / Pinealon class), no Cagrilintide, no MOTS-c, no SS-31, no NAD+
2-3 business day order processing window — slower than the same/next-day fulfillment offered by Nova / Perfect Peptides / Stillwater BioLabs / Pantheon

Testing Methodology

Every batch HPLC-tested by Janoshik Analytical (community-independent peptide testing CRO). DelixLabs publishes the per-batch verification key for every product on /coas/ — customers can paste the key directly into janoshik.com/verify to pull the original signed lab report from Janoshik's own site. Vendor doesn't host or control the verification surface, which is the strongest possible verifiability tier. Recent BPC-157 5mg COA: 99.034% purity (verified Dec 2025).
