Hey guys sorry if I ask irrelevant question here.

http://forum.lowyat.net/topic/2214445

I posted my question up there but no one reply so trying my luck here.

I have been working out for 2months now and consume weight gainer for about a month after my workout. I just finished my weight gainer and was wondering should I keep consuming weight gainer until like 75kg then cut down back lean or getting lean now with more muscles?

From what I heard from seniors from my gym, they said whey is for muscle growth when u have enough mass? Is that true?

So now question is I should buy whey or weight gainer?

Thank you very much!
