if you read his first post you can see it's 2 bottles that are a combo of trib and ZMA. the trib will only raise test a small fraction, although I don't know the MG's of the ZMA and trib per pill, im sure that ZMA is the dominant suppliment in this combo as you seem to agree, so then the question is when is the best time to take ZMA. taking trib in the morning or noon/night pre or post workout instead of an optimal time will have an insignificant effect compaired to taking it at all. so im sticking with before bed.
