A good/cheap trib product is FUZE by scivation.

But i gotta ask why you want to take tribulus, IMO trib products dont do much, they really wont help with mass gains, and the test boosting effects are inflated to say the least. The only thing it may give you is a slight libido boost, which if your coming off an aas cycle, or having problems in that area is cool.

as for the timing, trib should be spread through the day, cee pre and post workout, and i'm pretty sure zma should be used right before bed.
