my lab rats had great results in the past using chemicals obtained from chemone research and research stop. i ran tests using nolvadex, exemestane, and toremifene; not all at the same time - LOL! both companies provided good quality chemicals that were shipped very quickly!
the lab rats had best results using exemestane and toremifene. nothing bad about the nolvadex, just the results were more conclusive with toremifene.
i just recently ordered chemicals from ManPower research. primarily exemestane for a study that i am preparing. not sure about the potency of these chemicals, but the pricing was very competitive and the company shipped them to my lab extremely fast! great website and customer support.
