Universal & Evox stack - any good?

I've started taking Universal Animal M-Stak, Universal Torrent and Evox Muscle Punch 3D , along with a strict diet and Evox Synergy whey protein shake. Just curious to know whether the supplements I've chosen are any good together?

Have been told I should give a DHEA and Tribulus supplement a try - took two pills today but am thinking of stopping it. Thoughts?

I've been reading studies on tribulus and what I gather is that it is ineffective at raising levels of testosterone. everything else looks great, wish I had the money
Evox synergy is my favourite shake of all time and M-stak gives great strength. good luck
