Yes.. about that.. I don't really have any idea about how much I used last time since a friend prepared it for me :$
I must say I felt a LITTLE bit of a rush and a great mood change, but I think he put too little in there..
I also have a suspicion that I might have a little natural tolerance since I tried codeine a couple of times and I once used about 24 pills with 8mg each (total of 192mg) and didn't really feel anything..
There's no such thing as "natural tolerance" my friend. People aren't born being able to shoot 4 bags of heroin if you catch my drift.
What there is though is many factors that come into play especially with orally ingested opiates.
For example what and how much you ate before, how much you weigh, different people react differently to everything, etc.. So just because you had a little "tolerance" to codeine way back when doesn't mean you'll have any tolerance to a real opiate like heroin..
If you were saying maybe you have a tolerance because you've taken codeine a couple times before, that doesn't happen either
From what it sounds like you're inexperienced with opiates not to mention IVing anything(No offense and there's nothing wrong with that.). All I'm saying is it sounds like you're alone right?
You have a very vague idea of what you're doing. Maybe it would be a good idea to wait till you get home? If you're on vacation idk, or wait till you're with someone who IV's of knows how to IV.
Also, I don't know where you're from or where you first tried heroin but are you aware that there's different types? Ex. No.1, No. 2, No. 3, No. 4?
One needs heat, one needs acid(Vitamin C powder or white vinegar) to shoot, One needs neither, One is better for smoking, One is better for shooting or snorting, Etc...
In Europe they primarily get No. 3 heroin, not like us in the US who get No. 4.
So in that case you're gunna need to learn how to cook that kind, you'll be able to find it on this site or on opiophile.org which has users from all over the world like this site.
With No. 3 heroin you need an acid(like when shooting crack), Ascorbic acid or Vitamin C, or White Vinegar are the best and safest. If none of those are avail. Lemon juice works but is dangerous and has been known to cause health problems and infections in some cases.
So I'd be willing to bet you have no tolerance what so ever, judging by your history so you need to be careful.
Also, you said do key bumps and when you get off do the total amount? No.
Heroin doesn't last long and if you do key bumps and then wait 10 minutes or more in between by the time you find the "dose", some of the bumps you did earlier on will have already wore off.
You have to take half life into account too.
Dude to be honest this sounds like a bad idea, I'm not trying to talk you out of it just my opinion. I and others will help you out if you have your mind made up.
Snorting heroin does not have the same bioavailablity as IVing also. So your snorting dose isn't the same as your IV dose. It's a little lower.
You know what man? I HIGHLY recommend that you just smoke it, granted it is No. 3 Heroin. It will be bomb, not bad compared to IV. You still get a rush and most of the time it lasts longer than IV.
Wait till you're more prepared to IV it. Smoking is really easy, especially with that kind of dope. It's so much cleaner than tar.
If you're set on IVing, or if you want to try smoking. Or fuck if you want to know anything about heroin I suggest you look through this amazing site.
Heroin Helper
Click on the tab that says "User", and "Curious" if you want to learn more about heroin.
User, will teach you how to safely and correctly administer heroin any ROA. With pictures and whatever else..
But again, I'd suggest smoking it.
If you're from the states you're not gunna have a chance to smoke heroin that clean out here. From what I've heard the dope in Europe isn't that good anyway, so wait till you get back with your boy and IV some good shit.
If you want to know anything that isn't on that site feel free to ask anyone here.
Peace,
