Whats a better muscle multi-vitamin for muscle m, Optimum Opti-Men, or Universal Animal Pak?

They're both great. One or the other won't be a bad choice. Now is the big difference. With Opti-Men you only have to take 3 tablets daily. If you taking other supplements, that's the one you want. Now there is a little bit more ingredient in Animal Pak. But you have a lot of pills in those pack, not exactly sure but I believe between 8 to 12 pills per pak. If that doesn't bother you, go with a nice 44 pak, and if you're working out hard. Take 2 a day. Otherwise go for Optimum.
