I got my Winny V from a vet for 175. It's 100 mg / cc. Comes ina 20 cc bottle, so you take that EOD it'll last you 40 days or so. Might have been kinda high priced, who knows, maybe I could have bargained with him a little more, but money wasn't an issue.
As for the Clen, don't think you can go wrong with them. Don't think there are many counterfits of the stuff out there. It's AKA Oxyflux down in MX, or maybe that's just the brand name. Tell them you want Clenbuterol, and they'll know what you mean.
In MX, your clomid's gonna be called Omifin. No fakes of this stuff either.
As for the gyno - what are you cycling? Just the Winny and Clen. Mild cycle; should produce no gyno, so I wouldn't worry about it.
