Looking at the ingredients of the Anavite supplement it seems that some ingredients coincide with the active ingredients in TRX2 (for example, L-Carnitine). TRX2 will not have any adverse reactions with the elements of your regimen per se, and given that your metabolism is probably quite healthy, one wouldn't expect any side-effects when combining TRX2 with other supplements. However, taking too much of any one ingredient can be unhealthy. A compromise may be to reduce the dose of the Anavite supplement or to switch to a different supplement (for the purpose of bodybuilding) containing ingredients that do not coincide with active ingredients of TRX2 (at such a level).
