I have been using animal stuff for years, mainly Pak, flex. In the last 8 months or so I've been through almost all of what Animal has. I currently use Pump/Nitro/Omega/Pak/Flex/Mstak. I take mstak an hour pre, pump 1/2 hour pre and nitro 10 min pre. Intra, just started with amino's and 40gs of WMS and have been doing post, WMS and nitro then an hour later I eat. I've been researching Shock// and would love to try this comparo out. Thanks Animal.
