IMO fina should be run with a test ester. It'll help your gains and your sex drive. Trust me on this, I tried it alone and I had no desire to perform. I also believe that you should save it for the second cycle. The biggest complaint I had with fina is, bad back pumps (need more water), Fina dick (already discussed), fina short temper syndrome (had to decrease the doseage). Fina will also shut you down, hard. There is the risk of the dreaded fina cough, never had it, however the people that have are terrified of it, and the problem of frequent injections.
