Look man, there are some things you really need to know first....
#1: ok he is 300 pounds? And he is does not want people to think he is juicing? Let's not be silly here...
#2: get his diet in order, cut carbs down to a minimum...
#3: forget juice, diet and do some ECA's or like Nutsoe said, clenbuterol...
#4: No
steroid makes you "cut". NONE....Now with that said, there are some compounds out there that do not have the water retention that comes with others.....that is where the whole cutting
steroids come from. When there is less water retention, the muscles are harder and appear more ripped. do not be fooled into thinking that it will just melt the fat off...only diet and training does that..now GH, clen, DNP, ECA's,yohimbe, these are drugs that do burn fat too some degree....
If I was your friend this is what I would do....
For prolly 6 months I would diet like a mofo, train hard and do adequate cardio....I would also take an ECA OR clen at this point... since he already has considerable size, he has a lot of potential.....DIET is key...
protein,
protein,
protein....
THEN after I was down to 10% I would do this cycle: (again this is if I was him)
Ok when he has made signifigant progress
EQ or Fina --- EQ 6 - 800mgs a week FIna --- 75mg ED
Sust --- 1
amp EOD (250mg)
Anavar -- 30 - 50mg ED
GH -- 6-10 iu ED
T-3 -- .25mcg ED
Maybe some clen...
This would be the way to go IMO...
