tren
Trenbolone acetate which is in fina is very toxic to the liver, more so than sus but less than anadrol.
the reason for injecting it intramuscular is that it avoids going through the lining in your stomach and directly into yhe liver versus if you eat it you would send it directly to the liver.
injecting it would allow it to travel through through the muscles aand ultimately into the liver and then the blood stream and back again until it either binds or gets converted.
It is true that those pills have glue,fillers binders and other stuff.
all of which can be gotten rid of by using a solvent like methanol
to extract the pure tren.
But you know that it is highly flamable and needs ventilation when doing it this way. And of course measuring it will also be Important. But then you would have some very good clean tren which you could dissolve into oil and inject.
look up dan duchaine's method in his book.
