Shurink 300 shots

Last month, I looked at something like a Shrink 300 shot Facebook page and saw a lot of advertisements for cheap prices, so I tried it. (I didn't even think about VAT and got hit in the back a little bit.) But I remember that Jang Seong-gyu's hit on Wassup Man was Shrink, and it looks just like that. I was expecting the effect to be dramatic, but even after 2-3 weeks, I couldn't feel much of a difference. I wonder if it's less effective the older I get. I don't think I 'll do it again. It doesn't hurt much, and I just feel bad during the procedure. A tingling sensation? Something like that.. I wonder if other people have seen the effect.
