Although the method of making Finasol by basing it upon Androsol is convenient, it is not necessary.
You can make your own Finasol using some crushed Fina pellets and:
Isopropyl Alcohol (99%) and Isoproyl Mysteriate (spelling?) in an 80/20 concetration,
or
Ethyl Alcohol (thats grain alcohol, but it must be like 190 proof, or 95%) and something like PLO Gel (preferred) or DMSO.
Bascially you cursh the Fina tabs, add it to the solution, and put it into spray bottle. You calculate how strong (mg/ml) based upon how much Fina you added, how much Tren is in that (mg), and how much liquid you used (ml).
You then must know how many sprays/ml that your spray bottle is. You can do an experiment to determine that. I ended up spraying, spraying, spraying, and it took 325 sprays for 60 ml to be removed from the bottle which amounts to 5.416 sprays/ml.
With all of that info, you can figure out the number of sprays for a given dose.
Notes: I dont know ho much PLO Gel to use, I can find any refernces to how much to use in what application.
Iso Alcohol is slightly toxic, so that why you dont want to use it with a more efficent carrier such as PLO Gel or DMSO.
