Bro I just started it yesterday,I just read some peoples comment on quora and its says it's actually great depending on the time u use it..for example u can use it 3-5 times a week ..and not only the supplements will change u ur body but also the food u eat depends on it ..maletem do u know ur blood type,if u know that u can eat the ryt food that helps the serious mass..whe u prepare the serious mass u can mix 2 scoops with 600 ml of milk,1 banana,2 teaspoon of peanut butter to super charge it!..I saw some dude that gained 10 kilos ...he took the 2.7kg serious mass..I bought also this same one for 3,500 birr ...but on the market its avaliable for 3,600-3,800 deres...the best time to take the serious mass is 15 min after workout ....since it's a mass gainer it does 2 things as u like ....if u take it without working out just before sleeping at night everytime ..the mass will make u chubby ..but after workout is great cause it gives u gains on muscles!
