Stimulants IV Methylphenidate (Concerta) How much?

[GirlInterrupted]

Lets say...
I wanted to IV concerta (broken down to methylphenidate form as much as possible of course)
How much would you say is a good amount to start at?
I have the 27 mg pills of concerta. Lets calculate amount by pills. So maybe 2 or 3 pills broken down?
I'd like some tips especially from users who have experience with IVing methylphenidate before. But anyone can give feedback.

I know what I'm doing is unsafe. Don't question my motives. :]
Thanks

It isn't an amphetamine, it is just a stimulant.

Not sure if you are gonna find many people that have IV'd them, plus they have some nasty binders since they are ER.... Notice how they feel like hard plastic?

I ate a 54mg one at 6pm (eastern time) and am feeling it alot now.

My bad, it's just similar structurally. It isn't an amphetamine thanks.

I have the ER pills but they have extraction methods. There is a thread on how to extract the pills somewhere on bluelight.

Maybe it's because of the Zoloft that I'm taking but I can't feel anything at all when I chew up 54mg. I can barely feel cocaine. It's soo frustrating!
