I agree. 100 hurts sometimes, but 50 is ok. The only things that give me pip are water based winny,prop, and gear that is very concentrated. I have this test blend that is similar to sus but it is called Omnadren. It is 450mg and hurts bad. Leaves a lump for exactly 5 days. Every single time I use it I get the 5 days lump and pain. If I cut it back to 200-250 it is fine.
