Q: i bought this product 1000g.I received it and when i opened bottle cap the paper protector did not lock!protector paper was on bottle cap!is it safe?

I bought from GNC online store directly for 4-5 times already, seems like every time one of bottles’s inside seal was cracked open in the middle. It doesn’t look like a man made open, and the missing PCs was sealed to the cap. I would say it happens on the online store products. However, the cap seal vacuum seal was intact, it was just the paper seal inside.

Q: can i mix that with this Optimum Nutrition Instantized BCAA 5000mg Powder, Unflavored, 336g -

Yes you can. It's easily mixed because its a fine powder and can't even taste it :). I put both into my pre and post work out protein shake. If you're big into lifting I would use it 3 times a day.

Q: Is this product American made?

Yes, it is made in Optimum Nutrition's state-of-the-art production facilities in Aurora, Illinois, USA.
