It will work, but is a tremendous waste of tren. For my first cycle I took 2 bottles of androsol, dumped 3(!) carts of fina in each, and sprayed about 100-150 sprays a day. Those two bottles lasted me a whopping 4 weeks. I did blow up to the extent that I got booted from my gym (I also was using a little anadrol and winstrol). So there is some merit to it. It is much easier to inject though, and actually less of a hassle.
