i am a genetically disadvantaged 16 year old gym goer. Im reasonably skinny, weigh only 67 kgs and have recently purchased a tub of Massive Weight Gainer to help build my mass. Do any of you have any comments or suggestions on what i could take once i buld this mass (i.e. toning it). From what i remember the store had other supplements such as Creatine, whey, fina, and muscle builder. Again, any suggestions on these topics would be greatly appreciated.
