I just want to give an understanding how just how good Atomik's pricing is now with their new BOGO on GLPs. Tirz: 10mg: $50/vial @ $5/mg 30mg: $90/vial @ $3/mg 60mg: $155/vial @ $2.57/mg 150mg: $230/vial @ $1.53/mg Don't just buy bigger sizes because of the cost though. Buy based on the needs of your laboratory. But these prices are INSANELY good. They also have some of the broadest selection on other products across the board with great pricing overall. You can use my link below to order and the BOGO will apply when you add a product to your cart: https://atomiklabz.com/aff/17/
