The only thing I saw in CR is Sust and Deca preloads, and believe me I went to every pharmacy in San Jose to see what they had. I didn't ask about any PCT chems, but I'm pretty certain they would at least have nolva and clomid. You might be able to get some vet grade gear from the veterinarians, but I had no luck, but I could of looked a little harder. I know I checked a website and there is a pretty big vet grade company that distributes down there.
If you would like some ideas on where to go you can PM me.
