Quick, affordable, no disappointments!
They seem to be very confused about how their refund policy works, specifically members of the customer service team and sales team. Website contradicts most of their claims about returns. They are alright overall.
Good I like them
Love these. Fast onset and last about 2 hours. Will buy again if any are left by 7/30.
Awesome as always
I thought these were a nice mid-range dose. I always quarter mine. I would buy them again..
Haven is hands down the best high dose tab. Grape is 140mg according to COA
Excellent product I never had before I’ve ordered from them in the past and I will definitely be ordering again. Great flavor.
Liked alot but a little expensive.
taste is good
I’ve always loved this brand. The mango wasn’t my favorite flavor though. Everything else was great.
Works great tastes great im happy with my purchase.
It's a good flavor and a break from the blueberry and the strawberry. Which are pretty sweet. Seems to be a little less sweet and it works exactly the same as the other flavors. I actually get pain relief for some rheumatoid arthritis by using this product. I'm grateful it's available, but I understand it might not be for long.
One of the best when it come to reliability
I like it. It kinda guarantees my shipment and I don't mind paying the few bucks.
