Well I have tried Methyl-Dien which is a close derivative of Trenbolone and I know that Bruce Kneller and several supplement companies touted this oral supplement as being 10x more potent then Trenbolone but in-vivo in my and several others that I know experience- this never paned out.
I noticed nice strength gains but nothing that I haven't experienced on D-bol or Methyl 1Testosterone. The sides is what I couldn't deal with. Headaches, water rentention and high bloodpressure. Blurred vision, low libido and hair thinning.
I would definitely suggest superdrol, winstrol or anavar then Methyl-Dien but this is my personal opinion.
