In my opinion man, you can do what you want if you wanna buy max-out for $50 bucks go for it yes you will get stronger, yes you will gain some size, if everything is in place, diet, training, recovery, getting the right amount of cals and lots of protein all that comes before and supps man. Also at 17 you can take a ph not telling you to but yes itll get you ripped, lot stronger and yes lean mass gains not sure how good hyperdrol x2 is so if you decide to take one make sure you look into your options and read the logs on the forum first man. To me i would take a break from supps for a month or two just load up with some protein some whey its cheap or whateva you like and cheap creatine like some mono, or ethyl ester and hit the weights hard, then rest eat like a horse if your trying to bulk up than try something else like max-out or some test boosters, at your age man your test levels are higher than cheech and chong are daily man lol you know. but good luck hope it all works out for just remember to do your research like you are now man
