Skye was my first purchase. They sent me a second vial for free as a welcome present, and my 5mg vial was overfilled to 6.3mg. Fast delivery, they sent me a hand written thank you and welcome note, and the product was great. I moved on to another vendor now that I have found other vendors for my kits of ten but I've ordered single vials of other peps to try from them before buying in bulk elsewhere. Always a good experience.
They ARE a domestic seller, so while they're exponentially cheaper than compound, they're also way more expensive than buying direct from China. But their product is good and I've never heard of anyone saying they had an issue with them other than price.
