Just wanted to thank Emily and Billy for help with a delivery issue I had that wasn't their fault, but fixed the problem within days. Thanks so much. I will definitely be ordering again from Blackstone Labs again. 5 stars

Taste is good. But the mixability is awful. Like the product has been sitting somewhere forever and is outdated. Have to shake it to death before each drink

perfect service, step by step updates on tracking and very reliable and fast, always. Order every month. Never had any issues!

I’ve had nothing but pleasant experiences with blackstone labs. Transaction is smooth and delivery timing is usually as described.

My order showed up on time and I couldn’t be happier with Blackstone Lab’s GlycoLog & MYO-STACK.
