Up my doses?

Im a 35yr Male been working out for the past year or so and in the past 3 months i been real serious about it.

Workout 4 days a week
day1 - Arms,Abs
day2 - chest,back
day3 - rest
day4 - tris,legs
day5 - shoulders,Abs
rest on day 6,7

Creatine pre workout Juice:
i take 5gm of creatine a day
with 500 mcg chromium picolinate,
200mg alpha lipic acid,
dextrose and grape juice

Animal Pac Vitimins
3000mg HMB ( 1500mg with 2 scoops of protien mix after workout and befor bed )

20mg M1T ( 10mg twice a Day -cycling 2weeks on 2weeks off-)
25mg DHEA ( before bed )
1600mg Chrysin ( 800mg twice a day )
3000mg Tribulus ( 1500mg twice a day )
8000mg L-arginine ( 4000mg befor workout and 4000mg after workout )


ok i have a few questions:

1: Is stacking L-arginine and creatine ok?

2: Im on my last day of my 12week cycle of M1T should i up my dose of 25mg DHEA to 50mg or higher?

3: Should i up the doses of my Tribulus and Crysin? and if so for how long?

4: Are any of my doses a waste of time? to much? to little?

how is that 2 weeks on 2 weeks off thing working for you on the m1t?

id bump that trib to 4-5 grams aday .

very interesting cycle to say the least.

I feel the 2 week cycling worked out good with no side effects that im aware of....iv gained 15lbs over 10 weeks ( i was 151lbs with 18% bodyfat...now im 166lbs with 9.2% bodyfat ) I really can see and feel the differance.
But from what iv read from other peoples gains .. im wondering if i should raise the M1T to 30mg-40mg if i choose to do another 12 week cycle and was wondering if i really should be breaking my doses up so i can take it twice aday?..i mean maybe i should be taking my M1T only once a day full dose?

15lbs in 10 weeks is nice gains, no doubt .
