I have not used anything from Vermodje, but I hear good things about them. Naps has been in business for a long time. They have a great rep and the thing is, they wouldn't want to ruin that by carrying bad products. If you want to go with something I have had personal experience with, you could always go with GPs Tren E, which is a great product. GP used to have a Tren Hex, but they stopped producing it.
