Good luck finding it International. I’m sure it can be done, but outside of PPL most of us here aren’t going to know where to go.
FWIW it seems a lot of the hype surrounding Trest has died down. The battles people go through to keep their estrogen in check made it such a nightmare. Add in the fact that the compound is pricier compared to doing your tried and true cycle/blasts and people just seem to have decided to stick with what they know and love - good old test + Deca/Tren/whatever blasts that they already KNOW how to control their estro when running and don’t have to live in fear of growing titties.
Good luck. If you were looking US domestic I could steer you the right way.
