Pump Chasers GAF Whey - Whey Protein Powder

Pump Chasers GAF WHEY™ is exactly what the name states, it is Good As F@#%. From the quality to the amazing, unparalleled taste, this is the perfect protein for you. The perfect blend of Whey Concentrate and Isolate, GAF Whey ensures that you get the active biological fractions in the whey concentrate but also keep the carbs and fat low with the isolate.


The workout is over. You’ve attained the highly coveted pump and made all kinds of gains. Now, it’s time to replenish those depleted muscles and give them the hefty dose of muscle-building amino acids they need to repair and GROW.

The only option for fueling those post workout gains is whey protein. It’s fast-digesting, easy on the stomach, and naturally rich in all the essential amino acids required to fuel muscle growth, especially the all-too-important BCAAs. Whey protein is well known to aid muscle growth, hasten recovery, and enhance fat loss.[1,2,3]

Pump Chasers GAF Whey includes two highly bioavailable forms of whey protein, in whey protein concentrate (WPC) and whey protein isolate (WPI). WPC comes in all grades, but GAF Whey uses the highest quality concentrate possible in WPC-80. This means you maximize your protein content per serving while avoiding many of the fats, carbs, and lactose that cause bloating with other cheaper proteins on the market.


Whey Protein Isolate (WPI) takes the purification one step further than concentrate by removing even more of the fats, carbs, and milk sugars to yield a powder that delivers at least 90% protein. This makes for an incredibly high protein content for very few calories. It’s also ideal for those with dairy sensitivities since there is virtually no lactose present whatsoever.


Depending on your individual protein needs, mix 1-3 scoops of GAF Whey into 6-18 ounces of cold water or milk (6oz per scoop) in a shaker or blender.

GAF chocolate peanut butter whey

It is the best tasting and best quality protein I’ve ever had, no joke. Every time I have someone try it, their eyes widen. They’ll ask what’s in it and I tell them just protein and water! It’s THAT good by itself. I’ll never buy another protein brand again.

A damn good protein

The taste is great, even with just water. The chunks of chocolate and peanut butter add something for myself. Great product and will continue to use this!

Quality Protein

Tried this on a whim for a change from my usual chocolate flavored proteins. Taste was very good, but it’s very thin w/water, milk may be a better choice to mix it with. Numbers are excellent. A quality protein, but a bit pricey. Will try another flavor if I can catch a deal.
