i have a book called injectable dipearsed systems that has some info on this type of thing. it can be downloaded here free if anyone wants it.
a cyclodextrin tren sublingual could also be made. it would require frequent dosing probably. idk i read a study one time that showed a large single dose of testosterone given once daily was more anabolic than the same dose spaced throughout the day.
it sux not having the resources to play around with this stuff.
