creatine assuming it is pure product is perfectly fine at a proper dose.
the cytogainer belongs in the trash. i looked up the first ingredient and it was maltodextrin, do you know what that does when it hits your body? it spikes insulin and your body panics and starts storing fat. and then i saw more processed ingredients made in a lab, and even some cancer causing things too.
i understand you want to gain weight, but this is NOT the way i teach it atleast. i want you to build QUALITY mass over time. not get fat fast.
get on a good workout and diet program, take your creatine, and you could even grab some n2generate as a natural test booster. that is it.
