i was told not to take a suppliment  like protein until ive been iin the gym for a month , so that i build some muscle first .. and if i were to take the protein now while i start ill be putting like fat over my muscle and it wont look tight... it would be like flabby pecs?? is that tru?
 also , i read thread about all these crazy ass suppliments and evreyone seems to take so many different things , i wanna take protein and eventually do a cycle or creatine , will that show me significant gains with the proper diet and routines...?
im still new to it , and not sure if  im doing the excersises right , thats the most frustrating part , even when i see videos and diargrams i feel lik e ill be doing something wrong..SO FRUSTRATING. i wanna gain 30 -40lbs..... and atleast 15 by summer , wish my like and gimme any advice u can , thanks

Read the article first. Get your eating plan together, and training routine together (base it on compound exercises mainly) before you use any supplements.
