There are UK retailers that sell superdrol, the compound in M-Drol. You would be better off getting another brand since CEL discontinued MDrol years ago, and it's increasingly hard to find legit CEL OG stuff. There is a retailer in the uk that has a j and a w in the name that sells a product called sd rebuild...but I wouldn't know anything about that
keep in mind though that this would not be a beginner compound, is extremely liver toxic and very suppresive. A SERM in PCT would be mandatory.
