Fina Spray? At your local drug store. bwahahaaha this post is hilarious in itself. This is why the search button is available, so people can look things up. They have a fina board also on elite, you can check that out as well.
Fina spray is made by crushing up finaplix-h pellets and adding them to a (most likely) to a spray on hormone. although it still has the fillers in the solution, it also has the tren.
Not to mention making an injectable isn't much harder and you're getting over a 90%(with conversion and injection loss) yield vs the ~20% from a transdermal. Basically, you're wasting a good drug.
Have not used fina, but have read many posts on transdermal use and all have had good results. I know fina injections are more potent, but do you really want to inject ED or EOD? Not everyone is willing to do that.
you do realize insulin needles are meant for subcutaneous injections. I always thought it was better to get far enough into the muscle, so people used 1.5" for glutes and 1" for everything else. Maybe getting away w/ 5/8" for delts. Now I'm not saying you're wrong or right, or questioning your knowledge in any of this. Just never heard of using slin syringes for IM's.
