Vendor-supplied · Not verified by PeptideBase
What this vendor publishes about itself, repeated here. Disclosure is not verification; only independent lab results change that.
12 certificates on file, all self-published by the vendor. Median purity 99.56%, against 99.66% across all 1,295 certificates we score. Six of twelve compounds test at or above their market median. The exception is a IGF-1 LR3 lot at 96.68% — 2.25 points below the 98.93% median for that compound (n=11), and the only result here outside the corpus's middle 80%.
Evidence provenance
- 12 self-published
- COAs the vendor posted on their own site.
Recorded for completeness. A self-published document doesn't count as confirmed on its own — the document is real, the chain of custody isn't independent.
Purity vs market
