i am 21 yrs old and my weight is around 65-66 kgs. i've had typhoid twice within 6 yrs. i go to the gym regularly and want to gain body mass and strength. my gym instructor advised me some oral medication (alternative to expensive whey protein powders) which includes menabol, Liv52, A to Z multivitamis, Cipcal, Celin500, Evion400 & Andriol testicaps. i've not yet started taking these supplement medication. i'm a first timer, so am i on the safer side? seeking your advice.
