After lifting, there is a critical anabolic "window of opportunity" that exists. To take advantage of this nutritional period, take a pack within 15-30 minutes immediately after lifting. Even better, take 2 packs on your training days - the first preworkout, right before lifting, and the second postworkout. If you take a PWO shake, then take the Animal Nitro first, and then wait at least another 30-45 minutes before drinking that shake. When possible, take Animal Nitro on an empty stomach, preferably with 8-12oz. of grape or other fruit juice.
