AP is a must have in a high-calorie diet. This is a KILLER plan my friend.
I actually recommend this to every individual that is having issues gaining weight. This is the main point here - You can take in as many calories as you want, this really is not the issue. The issue is the amount of calories (proteins, fats and carbohydrate) that your body can utilize.
With Anabolic-Pump, in combination with a weight-gainer powder (for example), your body can store and utilize MUCH more of the nutrients you take in. Rather than normal 'going in one end, out the other' effect, you will see a positive glycogen feeding (MGU - Muscular Glucose Uptake).
This will become apparent when you FINALLY being to put on muscular size and FINALLY being to utilize these nutrients you have been shoveling in your mouth.
This increase in MGU alone helps counteract a 'short' gastrointestinal tract and a leading thyroid; common components of the ectomorphic somatotypes.
Additionally - With Anabolic-Pump, you may see a slight increase in the urge to consume carbohydrate. Poor hunger (high carbohydrate tolerance) is ofter the 'Achilles heel' of the ectomorph.
