If it was real. You will tell. Great pumps. First time I used. I was out eating and everyone in the place was staring. My girl said, you look like you just left the gym. She noticed I was pumped and was off from the gym for two days. Not sure what you had but. If you were training and eating well. The pumps are unbelievable. I've been lucky to work in countries where these products could be bought and sold without issues. That experience alone help me tell bull crap. I do take into consideration. If you don't take a break A/S is not as good as your first experience. This is why guys go up in dangerous dose to achieve that first blast feeling. But if they just come off for a month or two. It comes back.Primo and mast are not used for the same results.
