Works great

I love using this product as it keeps my energy levels high throughout the day. I can also say that I’ve become a bit more active and for this, I hope to shed a couple of pounds with time.

Did not work for me

I wasted my money getting this supplement. I used it for a month and did not see any change, not even one of the claims made was a reality to me. I was hoping that it’d make me hit the gym more but nothing – I’m still the old lay guy.

I can’t go without

Works well and I highly recommend it. Gnc Mega Energy to me is the real deal as it helps burst my comfort zone bubble and now am able to go around my chores with ease.

This is a no

I only used it for a month and I hated the aftertaste of the pill. Well, the few weeks I took Gnc Mega I didn’t see any notable difference, everything was like before. Maybe with extended use, it may work – but I couldn’t just continue.

My husband loves it

It is the energy he gets after using the product that makes me love it.
