Shit man, I haven't tried Fina yet, but the way my body reacts to Test I don't think I'll ever "need" to try Fina (though I am curious). Test all the way Baybeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee!!!
Its about the inconvinience of injecting everyday , i hate injecting, the pain is no problem, its just annoying. If you think liking injections makes your more of a man , thats your problem. Also i might be a little biast towards fina, since twice i got an infection from it. I followed every precaution, and no other gear has ever given me an infection.
Fina gave me good results but I didn't eat enough on my last cycle so I'm sure I could have done better. I wish I could shoot it twice a week instead of EOD. Like you said shots are not to bad but they are annoying to do EOD or ED. Once or twice a week would be my dream shots for fina.
