We never copy values between breeders. Old School Genetics's Gorilla Glue 4 — Permanent Marker is not another breeder's Gorilla Glue 4 — Permanent Marker.

Have a lab report for Gorilla Glue 4 — Permanent Marker?

Breeders publish claims; a COA is a measurement. We cannot read them off anybody’s website — of 160 products checked, none carried one — so the only way they get here is if somebody sends one.
