Make sure you're fully informed going in. I felt ripped off when they tried to up sell me to a product I should have been presented to begin with but wasn't shared with me until the "follow up" visit.
Not only would this product have gotten the effects I wanted the first round without having to come back for more it is actually CONSIDERABLY less expensive,. I felt so deceived and clearly they don't tell you about the second product so they can use it to up sell.
I came here because it had 5 stars but it has 5 stars because they offer a free little B12 shot for yelp reviews. It's has been 6 hours since and I still feel so frustrated and ripped off.
