Purgo Labs runs its own discount of 25% off a first paid order, and several codes of its own that each take 15%. Every code needs a $25 product subtotal, only one code applies per order, and 10-packs are excluded from all of them. 10-packs carry their own discount instead: 35% off the most expensive kit and 45% off each additional kit. Prof. Peptide checked these codes with Purgo's own checkout on October 16, 2026.
Struck-through prices are Purgo Labs’ list price; the bold figure is the price once the discount code is applied at checkout. Prices current as of October 22, 2026.
Testing: Labs & Certificates of Analysis
Purgo publishes 182 certificates on its lab-reports page, from Freedom Diagnostics, SteriGenix, ILS Laboratories, Kovera Labs and Ethos Analytics. Of the 155 whose text Prof. Peptide could read on October 16, 2026, 149 name Purgo as the client; the other 27 are image files whose client field was not read.
Prof. Peptide drew two Freedom Diagnostics certificates issued to PurgoLabs LLC at random and found each in Freedom's own records, which returned nothing for an invented code first; both lab copies were identical to Purgo's. One is for its GLP-3 R 30mg (99.98% purity) and one for its Melanotan I 10mg (99.63%). Prof. Peptide also opened two Kovera Labs certificates, for its Epithalon and CJC-1295 (no DAC), at Kovera's own verification page, which refused an invented link first; both name PurgoLabs as the client.
Two things on the lab-reports page, as read on October 16, 2026: six of the readable certificates are issued to a client listed only as “PS”, which the site does not explain — one of them, a NAD+ certificate, is genuine at Freedom Diagnostics, issued to “PS”; and the certificate attached to the NAD+ 500mg listing is the same file as the NAD+ Spray 1500mg certificate.
All products are sold for laboratory research use only.
