First let me be clear, I'm by no means pro synthol.
Thing is the people who use it correctly, you can't tell they do. So people only see the jackasses who look all lumpy and shit, and then think that's all synthol can do.
You really need some good size already to make synthol work, and also need to do multiple very small injects all around the muscle in order to make it look good.
Also, most can't do this alone so you really need someone with alot of knowledge of anatomy to do it for you.
You sound nowhere near at the stage to even consider synthol, so I would highly rec against it.
