Have tried Animal Pak, Animal M-Stak, & Animal Max Protein. I *think* Animal Paks are good 'support' vits/mins based on the label & what's in them...but it was alot of pills to take daily. When I took Animal M-Stak, I was on tbol, so the gains could have been tbol gains...but I was happy with that prod. I *think* the prods were alot better before the Steroid Act cut out all the prohormones...cause I *think* the Animal Stak had those in it.
Also, I never tried the prods for more than a couple of months, so that might have not been long enough.
It's best to try them for yourself & see if you notice any changes; since everyone reacts differently to different prods.
Hope this helps.
