Hey ,i want to ask about steroids im not taking any one but I was so skinny 4 month ago than I hit the gym floor and my trainer recommended a local mass gainer (1 kg ?2000), it does not have any side effect, but I have gained approx 8 kg in 4 months, and once I gained 2.5 kg in a week, I was shocked how can a mass gainer give that shocking result, since than I am worried it contains any harmful ingredients like steroids etc, please reply I am taking it from last 3 months and my 2nd 1 kg box is gonna finish, I want to know if it is unsafe how to get out safely. (I hv already gained approx 9 kg 20 months ago with 6 months workout and mass gainer, also want to mention that I had very poor diet 4 months ago) I can send pictures of mass gainer nutrition table but there is no option to attach pictures, thank you.
