I'm not one to give advice on GH, as I'm still in info-gathering mode. But please provide more info about yourself so others can help: size, age, AAS experience, current condition (BF%, etc.) and what you have on hand (someone may suggest something that "you" cannot get).
I guess it totally depends on how "crazy" you are and what money will allow.
Personally, although i dont compete, I'd use the following:
(Not all used at the same time, but they'd be used at some point during the cutting/precontest cycle.)
EQ - Always good.
Tren - Excellent hardener, good androgen, works AWESOME with EQ.
Oral Masteron - Been hearing rave reviews over this. Inj. Masteron was the stuff when i could get it. This would be used for the last 2-4 weeks before the show.
Winny - I'd work it in with the EQ and Tren.
Test. Prop - Daily injections. Could do 50-100mg of this with 50-100mg Winny each day.
T-3 - It's good stuff if used correctly.
Clen & ECA - Cycle them in 2 week intervals.
HGH - Dosage totally depends on the person and $$$. I'd use AT LEAST 4IU daily.
Glucophage - This has been coming up ALOT lately. Seems to have some great benefits. Plus you dont get the fat gained like you would from Insulin.
Anadrol - ONLY used the last few days prior to the show. Gets androgen levels nice and high to increase hardness.
Dandelion/ Taraxatone - Natural Diuretic. Helps rid the body of water. Could use Lasix if your experienced with it, or take small dosages. I'd consult with some previous users if you've never used it. Also be sure the constest doesn't test for it, the lasix that is.
Synthelator - used day of the show.
Thats a rough outline of what i'd use. Again, i dont compete and never dieted down to the extreme's for bodybuilding. I've been at 5.7% BF before, at thats about as far as i wanted to go considering i don't compete.
I'm sure some of the Pro's and Vet's will have some good input here. I'm hoping to hear some good ideas here myself.
