[Maxgain]

I remember i got an atlas weightgainer and everytime after taking it 24 hours later to the minute it was time for an emergency bathroom visit. Was strange it took 24 hours and was unaffected in a sig way by the rest of the diet. Just cut it out and got a different brand. No idea what caused it just malto and whey must of been an additive

Penta Protein
Product Description:
20% CFM Whey Isolate
20% Soy Isolate
20% Egg White
20% Aussie Caseinate
20% Hydrolyzed 1400

It sounds like Lady C has been a big help to you and why you had such a reaction. Much better help than I ever could have been.

I'm impressed you weren't put off by the taste of the hydrolyzed protein. That can make anyone's face grimace. Even more impressive is that you didn't add any flavorings or sweetener to the blend.
