What are your stats now?
Do you have low BF%? Yes very low.
Is your diet 100% perfect? No, but I try the best I can with the money I have ($30-$40 a week for food).
Have your lifts stalled? No still gaining
What is the reason you need this extra "help"? With m-drol i would be able to gain 5kg in 3 weeks. It would take me about 1-2 years to gain that much natural at the rate I'm going right now.
Also I'm 6'2" at 81kg, 22yrs old.
man you sound good bro, i wouldnt be trying them, i would feel lucky if i was you.
