Taking exactly what "he" takes wont make you look like him.
Everyone reacts differently to different drugs , you could take exactly the same as some guy you want to look like and not get the same results.
If its size you want test decca dbol tren anadrol are all drugs that will add muscle pretty quickly , its up to you to experiment and see what works for you .
Just take me exactly what to take to look exactly like him.
Thanks.
