It is an excellent product, the bottle lasts 21 days, you rest for 1 week and start again. I go for a week, combine it with creatine, protein, and a high protein, high calorie diet. Bring a capsule with stimulants so it also serves as a preworkout*

I suggest using a gainer with M-Stak for a calorie surplus and those extra carbs you will need. Also used Animal Stak with it to add some strength and definition along with the mass you will gain. Gained 6.5 lbs in 20 days.*
