- u already are doing the basics which work

rotein, mv, flax and creatine. glutamine is suspect to say the least.
- mv, flax already help with natural test levels. as far as other supps that are natural i would say save ur money for the basics u already have in there.
- the only other supps that might be interesting are the ''plasma expandors'' such as v2, v12, kreataine, satut8 and mid cycle
- look into stuff that helps with pre/post wo nutrition and help lower cortisol imho there lies the real potential for growth.
- zma only works for those who are zinc deficient!!!
- tribulus is suspect as well!!!
good luck
peace
