I had been taking the b12 mic injections but I do believe this liquid version works very well and it's less expensive Win Win

Fast delivery and up to date tracking!

I’m never disappointed with the speed in which I receive my order, the value or the quality of the product!

Excellent product will buy again

Bought this a week ago. Fast shipping and has reduced my appetite tremendously

It arrived quickly and i received great email notifications and folliw up. Good job

Too soon to tell about weight loss but it definatly improves my energy without making me jittery.

Great and on time

Great product

Potent stuff, after one day I can see a difference!!

Helps my energy level tremendously! Will be buying more because I’m running low

Fast shipping, taste good and hoping for good results to early to tell

I've always had great service, and fast shipping.

I have used this product for several years. I do not use it as a weight management tool. I find when I'm really tired, it's a fantastic wake-up for my brain!

the taste is not bad. I can tell the difference in the way i feel.

I love this product it gives you energy and alertness. The only thing is when you buy from Groupon you have to go through steps of redeeming a voucher, which takes extra steps to get your product.

Everything went well.

I’m on day 4 and I’m excited to see the outcome. I feel energized and happy, motivated to continue working on becoming more healthy.

Taste good.

So far a good product. First time user.
