We never copy values between breeders. Dr. Underground's Crystal M.E.T.H. is not another breeder's Crystal M.E.T.H..
Lab data
No lab report here yet
Have a lab report for Crystal M.E.T.H.?
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.
Same name
3 breeders sell a Crystal M.E.T.H.
A name is not a genetic identity. Each row is what that breeder published, on their own page.
