I try it 10 yerars ago. it worked, but it wasn't like steroids or the real HGH injections. I bought it in a Pharmacy in another country. They sold it on the internet for a while until the FDA didn't approve it anymore and just classified it as a drug just recently. So I did this thread to see if anyone knew how to can get trans-d tropin now that the website doesn't sell it anymore over the internet. I would like to try it again. I wanted to see if there was another hgh supplement that I could replace Trans-d tropin with, but I guess there isn't. I guess Tropin-d tropin isn't illegal yet in the USA. I think its a good subsitute for the real thing if you don't want the side effects, but you won't get as good of results as the real thing. It will just take a little longer to get to your goals, but it works.
