I remember reading about those old homebrewing kits. Seems pretty sketchy trying to make a sterile solution of it.
The old PH tren is just pro-dienelone, you can get the active form in the product trenavar from various online websites and its currently not on the scheduled substance list. I'm also not a fan of sust, too many different esters makes it difficult to keep steady levels at any given point. Test e/cyp is more favorable IMO
