As said above mate Tren is pretty harsh. Doesnt hold much water which is great but does give you the cough and as said by someone above its the only sted thats made me feel angry sometimes. Defo good for strength. Id go with some test prop and maybe some winstol orals. Great course and you wont blow up like a balloon which you would with sus and deca. For the record i think that particular corse isnt even worth taking.
