Janoshik Analytical, 2026-08-04
57 sellers, 61 listings, 4 vial sizes, read from each store's public product feed on 2026-09-30. A seller with a recent certificate from a named lab ranks above a cheaper one without. Every card says why it sits where it does.
1 public certificate file we opened name PEG-MGF. That is a count of files, not a grade, and compounds are not ranked against one another. A seller-published certificate is not a blind test. Certificate search.
Some seller links may pay this site when you buy through them. A payment never changes a seller's tier or rank, and no seller has a say in any page.
Best value with a certificate: MyPurePeptide, $30.0 for 2 mg, $15.0 per mg. PEG-MGF 2 mg middle price is $23.6 per mg across 37 sellers.

PEG-MGF was first read on 2026-09-30. Middle price $19.4 per milligram across 57 sellers. A week-by-week line appears after the next finished weekly walk. One week is a snapshot, not a history.
The figure is the same ungated market median the range on this page uses: every seller found. Certificate tier still ranks the cards. The purity gate is written and off, so this is not a tested-sellers-only series.
We never charge for knowledge. No vendor has a say in what a page says. Sellers are ranked by the certificate they publish, then by price. Every seller, graded · Laboratories named · How this is counted
