I recently started using Gaspari Real Mass as my PWO shake. I am very happy with it so fat. Great taste and great profile, I actually look forward to drinking it everyday so no complaints. The weird thing is about 45 minutes after I drink the shake I AM STARVING!! Now since I am bulking this is a good thing,just wondering if anyone else has had this experince?? I even drank it today as my breakfast and after about 45 minutes was starving again....Is it because it is a fast acting shake ?
