I've used IMR SERMs - fast shipping, no complaints. Didn't do bloods for that one though. Clomid and Nolva are soooooooo old, they are out of patent, abundant, and cheap as dirt. You would have to be the lowest of the low company to sell fake Clomid/Nolva. One way you can tell (maybe, as it isn't 100% for everyone) is Hot Flashes on Clomid. You can also backstop by using TWO different companies product (or just find Rx - but even then those can be counterfeited too).
