thats because pmag is 4-chloro-methyl-4androstenediol, similar to the un banned compound, 4-chloro-methyl testosterone aka methyl clostebol.
and m14add is methyl boldiol, similar to methyl boldenone aka dianabol.
hdrol is more closely related, because it is 4-chloro-methyl boldiol, and is similar to 4-chloro methyl boldenone aka oral turinabol.
all of these diol's get their gains/sides from the compounds they are, and should not be thought of in any way as the more potent, stronger 3-ketone compounds the are associated with.
people chasing dianabol gains need to buy dianabol, not do something stupid like use 100+mg of m14add. same thing for pmag, and hd.
if you are looking for dbol, methyl clostebol, or turinabol gains, get some. 2 of the 3 compounds are very easy to get.
if someone is going to release a new hormone product, they should release methyl clostebol, as it isn't banned, and would be one of the most potent compounds available.
