i personelly love the animal product line i have taken their pac, stack, & m-stack for 2 yrs now........i have also used many other universal products and have been quit plzed w/my results from it.......although i must admit my body responds very well to very low doses of AS type products. i would also suggest checking out bodybuilding.com for a very good list of animal products and universal products. the only thing i havent tried yet is their new animal test although it looks good.and i havent recieved any sides from them .....plus most stac and m-stack are loaded w/additinal goodies to combat sides.........all i can say is do yur research on the one u want find a good price for it and give a try........

animal pacs taste disgusting and is really hard to swallow, takes like 3 glasses of water. But thats just my opionion. on a good note they are good products if you can find a good price
