Humapro is a ground breaking new product for serious athletes & bodybuilders alike! Having used dairy based protein powders for many years, I was introduced to Humapro by a friend who ran a supplement shop. Everybody who has used dairy proteins knows all too well the bloated heavy feeling they give you which makes working out after the shake very difficult, unless you like watching guys vomit during a lift! I have used Humapro for a few years now, before & during workouts with no problems whatsoever! Its so light on the stomach, is engineered for the human body, has almost no calories & tastes great! It is, without doubt, the leanest protein available! Save the heavy dairy proteins for after your workouts!!! Absolutely LOVE this stuff!
