What do you mean by it never works for you? If only certain ROAs are working for you then it would seem to me that the batches you're getting aren't too great, no offense.
The order following plugging, yes. However, I don't think it can be argued that plugging is not the best ROA besides IM/IV. It's scientifically the closest you can get to IM/IV without injecting, damn near everyone who plugs any drug can confirm that it hits quicker, hits harder, and requires less chemical.
Not in the greatest mood, got almost no sleep after a show last night, so excuse me if I'm being harsh. I just don't see how you can argue it isn't the best unless you are opposed to sticking a syringe up your ass, in which case are you really debating the best ROA or your most favored?
