Hello I Would Like To Try+ Animal M Stak + Gaspari Size-on + Nutrex ... Good Stack Or Too Much ?
don't know what the vitrix is... but animal pump and size on are both creatines if I'm not mistaken.... Get rid of the size-on if I were you cause animal pump has N.O. too. M-Stak's a good choice. Also look into some bcaa's/eaa's... specifically Purple WrAAth or Universal Intra-AID.
Hope this helps bro.
Edit: I'm assuming you have a good protein and multi-v?
yea i take 100% whey from optimum nutrition and also a weight gainer. I also take animal pak for multi-v ... vitrix is a natural test booster
