This is an EXCELLENT bulking cycle that should give your boy 20-30 lbs (it gave me 30 my first time).
week 1-5: dianabol, 25 mgs. every day
week 1-10: deca-durabolin, 300 mgs. every week
week 1-10: 500 mgs. testosterone (sustanon, test. enanthate, or test cypionate) every week
2 weeks after your last shot take 40 mgs. nolvadex a day for 2 weeks, then 20 mgs. a day for 3 wks.
During the cycle, if your friend's nipples start feeling itchy or sensitive start taking 20 mgs. a day every day.
If you're in Mexico you should be able to get all this stuff at a pharmacy EASILY. Use QUALITY-VET brand veterinary steroids, they're the best. Tell your friend to eat at least 200 grams of protein a day and 4000 calories a day. This should work wonders for him. Good luck!
P.S- The Quality Vet brand names for these products are:
Dianabol (Methandione): Metavet
Deca Durabolin: Deca 300
Test. Enanthate: Enant (shit I forgot the exact name)
Just look for Quality Vet products and you'll be good to go
