As has been noted by others, this athlete needs to run much larger doses. There is a poster on another board called BFG who is privy to quite a few programs run by top 10 guys at the Olympia. These programs will blow your mind with the amounts of gear.
Here is what your typical regional level NPC competitor runs at 16 weeks out: 1500 long estered test, 600 deca, 500 mast (increase to 700 as contests gets closer). Start at 400 tren e (long ester) as contest gets closer increase to 700 tren ace. Start on 100 mgs/day of anavar. Most pro's take double that....Dorian ran 250 a day. 12 weeks out add A Drol, 100 mgs on training days. When you are this far out D bol and similar orals are fine. As you get closer to your contest (3-4 weeks out) add Winstrol, 100 mgs a day. 2.5 weeks out add Halotestin. at 3-4 weeks out swap the test e for tet p or test ace.
Most pros are usn A Drol to fill out the last few days. I do not have knowledge of how this work (they also are running diuretics and plasma expanders). I just use Halo, winstrol, and anavar to fill out.
If you can afford it, take at least 5 iu's of pharm GH a day. If you find a good Chinese generic make it 8 iu's a day. If you have the money, take more.
At 6 weeks out you should be pretty lean. Run a trial diuretic run to see how your body responds. There are 3 types of diuretics and they must be taken in very strict and science informed manner. There is a formula of ratio's of Aldosterone blockers, Thiazides, and lasixs. The tral run ill inform us as to how your body responds. Adjust accordingly.
Do not touch diuretics, especially Lasix unless you really know what you are doing.
I would have your guy run 500 test and 300 Deca in the offseason. That will be his cruise.
