i cant believe nobody here addressed a serious issue regarding the two substances...
deca is manufactured by several human grade pharmaceutical companies.
tren isnt!
so with tren, you're basiclaly forced to go underground.
with deca, more choices.
also, keep in mind that fina has WAY more sides than deca.
listen, deca has been around and has proven to be a very effective choice for bulking and/or cutting. stick with it trooper!
