There are a lot of factors that come into play in terms of pH adjustment of a solution of brown heroin (a.k.a. heroin no. 3 or brown Afghan, and so on, basically the base form of diacetylmorphine, which needs acid to dissolve in water, if one wants to use the substance for intravenous injection).

Life would be easier if someone had made a whole batch of heroin no. 4 instead (the HCl salt of diacetylmorphine, thus water soluble), for those that like to IV, but the smokers around the world seem to dictate the amount of China white and the likes on the market in any given place. I also think that producers can make more money off of brown heroin, than white, due to the loss of kilos upon conversion from base to salt (correct me if I am wrong), plus it requires restricted chemicals and so on... also why white is usually more expensive and less amounts are required. So the brown hits the market, and needs to settle both the IV and the smoker and the sniffer and the pluggers needs... and so instead, many are left forced to use acid to dissolve their DOC, and slam it, and I myself have been in that situation. Luckily I had pH strips, so I could check the pH of my solution before and after cooking. This was A) to make sure I didn't inject some motherfucking-acidic 0.5 pH shit, or B) some neutral solution where only some heroin might get dissolved.

I have made a study using three different types of street heroin, in its base form, a total of 5 shots.

Heroin type 1 was a light tan colour but became dark red/brownish upon cooking. It was of decent quality, around 40% purity I would say.
Heroin type 2 was a darker tan/brown colour, almost with a reddish tint. This heroin was complete crap, maybe 30% purity at best.
Heroin type 3 was a light tan color, but was not very dark red/brownish when cooked. This heroin was the best of all three, and an estimated 60% purity.

For the sake of ease, let's assume that each shot was about 50% pure, and that I used around 100 mg of heroin no. 3 for each shot, which was indeed the average amount per shot. Mind you I might be opiate tolerant, as I am on buprenorphine, but all shots were taken after a 3-day break from buprenorphine, and no buprenorphine was taken during the period I had the 5 shots of heroin. The whole affair was spread over a few days. I would recommend much lower doses for opiate naive people. So do not use this thread as a dosage guideline. It's about the ratio of acid:dope:water.

When Google and forum searching, the suggested amount is 1:10 citric acid to heroin no. 3. So the first time round, I used around 10 mg of crystalline citric acid (eyeballed - divided into tiny mounds from a 100 mg satchet). A little less was used for shot no. 2 and 3 (probably about 6-8 mg), while even less was used for shot 4 and 5 (somewhere around 5-6 mg). It seemed to have little effect on pH, but no effect on heroin dissolution. So the less one uses, the better, but there must be some optimal pH to aim for, which is why I started this thread, to find out.

Heroin type 1 was used for shot 1 and 3, and type 2 for shot 2, and type 3 for shot 4 and 5.

Another important element, is the amount of water used, as this will also alter the amount of effect the acid has on the dissolution of the diacetylmorphine base. I used 1.5 ml of bacteriostatic water (single-use plastic vials, 0.9% NaCl). The same amount of water was used for each shot.

I read somewhere, that the optimal pH for dissolution of all solids, based on some university study of some 60% pure - or thereabouts - street heroin, was a pH between 5 and 6. So that is why I tried using less for the later shots. However, I kept hitting about the same pH, regardless whether it was 5, 7 or 10 mg of citric acid I used. I guess the point is that the advised amount of citric acid needed is way too high when shooting street heroin that has been diluted, and it also depends on the amount of water used. I have attached some pics of my pH strips, for your eyes to judge...

The idea of this thread is to spawn some scientific input in terms of the optimal amount of citric and/or other acids to use to dissolve brown heroin for IV use. Because I would really love to know exactly how pure my heroin is and exactly how much acid and water to use to hit just the right pH, without having to use my precious heroin solution for dripping on pH strips and to not ever get a collapsed vein or the likes due to too much acid (it was hell just copping the heroin in the first place, so any other complications just add to all the troubles)... and sadly I don't have a scale that works, but over the years, the eyeballing has gotten pretty good. And either way, so long as I can't find any concrete information on the matter (I haven't put tens of hours into researching it, but enough time to know that the info is not easy to find, and there is a lot of debate, and a lot of crap dope out there). And when one wants to do something the 'right' way, it's damn annoying that there isn't someone out there who has found the 'right' answer already, so that one has to go about it by one self... and with that in mind, wasting shots due to too much or too little acid is a pain in the ass too... anyways, I'm not a heavy user, and I am planning on never really using again after my buprenorphine plan pans out, but if the time comes around, it would be so wonderful to be able to do it just right, by the book, and get the best results and minimal harm.

Here are some pics of the pH of shot 1-5 (tested before and after heating/cooking - note that the cooking process does little to the pH. Which means that the acid dissolves fast into water at room temperature, and that double-checking the pH after cooking is a waste of time...):
Click the show button below to see pics of the pH results that I got from testing my mixtures.

EDIT: Pictures no longer available. But there was little difference in the colour of the pH strips from the different tests. Much like there is little differece in pH of tested solutions in the following video about heroin and citric acid, where they first add the right amount and then add a whole sachet, from the producers of citric acid sachets found in UK/European needle exchanges and elsewhere.

I find it amazing that people actually go to these kind of lengths when using

Im not mocking you in any way at all, i think its cool what ur doing but i just have to go with what i think in my mind feels right when cooking up and get it in my system lol
 
If you are interested in this stuff study up on acid/base equilibrium. You are titrating acid into a basic solution in a neutralization reaction. Since we are dealing with a weak acid and a weak base, diamorphine pKb of ~6 and citric acid pKa of ~5, the pH at the equivalence point will be slightly acidic due to the citric being slightly stronger. Really though it doesn't matter that much as you'll want acid in excess to be sure you don't miss any diamorphine and deal with any funky equilibrium loses. Never mind how much the cut, whatever the hell it is, will completely throw this off ;)

edit:
I also think that producers can make more money off of brown heroin, than white, due to the loss of kilos upon conversion from base to salt (correct me if I am wrong)
The molecular weight of diamorphine base is less than any of it's salts.

Haha... :) Yeah right, that's why I'm also eyeballing everything... because I am doing it by what feels right... And the only reason why I went to these great lengths was because I don't usually shoot heroin, and since I had to try it, it was a great length in itself to do so, so doing it right seemed like a natural thing to do. But if I really wanted to do it 'right' I'd have bought a new scale instead of dope... and one of those cool lab-grade titration devices... and then the dope... hell... If I really wanted to do it right I'd be cooking a batch of my own no. 4 right now... pure as pure can be...

Thanks for the response... it does help a lot... at least it sort of generalizes the question, so that I might find my answer somewhere else in the literature, and then apply it to heroin no. 3.
 
Sorry I reread my post and see I wasn't clear enough in that for a weak acid and weak base like these the equivalence point will be effectively at pH of 7. In other words all the heroin base has formed a salt when the neutralization reaction stops occurring here. You can't really get any of a theoretically better answer than this. Practically of course the more acid in excess the better as it ensures you get all the base and helps deal with the big 50 percent unknown cut substance which effectively throws off any and all theoretical application.
 
^That's just the thing... the more acid in excess the better in terms of dissolving all the H... there are two ways to play, both ways are better safe than sorry. 1) Add at least 1:10 ratio of citric acid:dope or the hydrochloric acid equivalent of that, dissolve all your H and more, and risk getting tremendous damage to your veins, or 2) add as little acid as possible, and save a bit of the veins, but maybe lose a bit of the H... So I like that sweet spot between no. 1 and no. 2.... which is why I am on this quest... MAX HR, and MAX H!
 
I've often wondered about this myself as I lost all my best veins in just 2 years of iv heroin use because of the citric. I never had any problems when shooting speed and on a binge id be banging every half hour or so. The problem is that a lot of people just don't realise how acidic the solution still is after
cooking. I certainly didn't until I fucked up a shot one day and ended up swallowing it as a last resort. fuck, it was nasty. So I imagine plugging it wouldn't be too nice either :-)
 
^I had a little accident while chasing the IV heroin high, and had to decide whether to shoot the solution with flaky blood, toss it, or just say fuck it, and try it up the ass. So of coarse, all things considered, I could live with a little ass-burn as opposed to the knowledge of having thrown out a perfectly fine shot of heroin. And indeed it did burn, but very little compared to how much the vein burns right before that wonderful blast of sensations kicks in from a successful shot, and also very little burn compared to the day after a meal of authentic Indian or Thai food... So it definately should be considered as a safer and alternative ROA, and don't fear wasting the drug, or a burning asshole, because it will get absorbed if done right, you will get high eventually, and it barely burns at all... But with that said, I'd still like a more direct answer in terms of the pH (even if it assumes that the heroin is 100% pure, I'd much rather waste H, than waste my veins completely)...

i think its cool man i love learning about this kind of things :)

You and me both brutha! Hence why I posted... I just don't want to sit there years down the line, like so many other IV H users, and be like, "shit man, I knew that I was going overboard with the citric acid, and now look at me... can't even find a spot to shoot no more..." and instead of damning the heroin, we can damn the acid that was supposed to dissolve it. Anyways, today I couldn't leave the needle be, and made a 0.6 mg solution of bupe and shot it in the crook of my elbow, good old cephalic vein, still holding strong (although it has only been subject to a couple of heroin #3 shots and a bunch of bupe shots, I'm still amazed at the recovery rate, so I wanna keep that rate up there, and not have to suffer acidic damage to that part of me - would be awesome to have that spot for IV'ing the rest of my life, which would also spare me the slightly discouraging small-talk when the nurse eventually fails to draw blood from it during a blood test)...

Lol... but yeah, would be awesome if somebody could be like, if you have 50% pure heroin, the remainder coffee creamer and sugar, you wanna use x mg acid : x mg dope : x ml H2O... Not that people usually know what's in their dope other than dope, but still, some people are lucky enough to know exactly what sort of product they're sitting with, and from years of heroin use, I can also tell from a small line, whether it is close to pure heroin or not, and whether the the cook from #2 to #3 went as planned, or whether there is a bunch of morphine freebase in the mix instead of diacetylmorphine...

Also, if one wants to check what sorts of mixers are in the dope, a good way is to smoke some on some foil, the good 'ol chase of the dragon, and check out the ashes and trails on the foil... Heroin will leave very distinct trails that are recognizable with enough experience, that are very different if let's say a tiny amount of sugar is added to the mix, which is bad for the blood and the body, but will eventually get cooked in with the mix anyways, or you could be stuck with same old talcum powder... either way, somebody somewhere along the line wanted to make an extra buck, and there will be mixers, not to mention bacteria and other nasty shit in your dope, unless you got it straight from the factory, and even then, the chemistry might not be 100% pure diacetylmorphine, but to a certain extent freebase morphine that was in excess...

...Speaking of which, Morphine HCl is a wonderful drug to IV... so wonderful. Judging from the different types of dope I shot, and the effect I got, the good thing about filtered Morphine tablets is that the chemistry is right, and at one point, I had myself convinced that Morphine HCl was much better to IV than heroin, until I got some good diacetylmorphine and hit the pH right. Then I knew that nothing can compare to IV heroin, and I understood why people call it the Holy Grail. Just looking at it's molecular structure compared to other opiates has me wetting my pants... I can just see all those little molecules so perfectly shaped and almost bi-laterally symmetrical dancing around and poking and clamping at my receptors... beautiful little buggers!!!

Usually the most common adulterants are either water insoluble, or are irrelevant to the pH of the solution... So.... somebody, tell us how much citric/hydrochloric acid to use!!! Would be awesome to be able to make a cold sterile mix, by using just the right amount of acid, so that heat is out of the question... Cause the heat really boils up some nasty mixes out there... But most people I've talked to with IV heroin # 3 experience, make claims that their cold shakes are always less effective than the hot ones... Another factor in the equation... heat and speed of reaction... patience is a virtue, and if it is possible to make a 100% effective shot of brown heroin, without applying heat but still remaining sterile, that would be something that even the most burnt out junkies who have a twitch for the acid itch can't say no to!

Anyways, I usually use a little less acid than what I feel like at the moment, just to be on the safe side (and safe side is up for discussion, as some would say that acid in excess is the safe side, to be sure to get all the heroin, while I am reluctant to take that stance; I would like to spare my veins, and then maybe waste some mg's dope, rather than burn my veins, and then not be able to shoot those mg's in surplus). This is judging from the testing I ran on 5 shots, where even something as small as 5 mg citric acid : 100 mg dope : 2 ml H2O had the pH and myself floored... So I know there are all sorts of different factors in the equation, but a start would be someone with extensive experience and little harm done, to tell us the ratio that they have been using year after year, while purely theoretical ratios would do as guideline amounts, so long as their contributing factors are outlined.
 
New update:

As fate would have it, a person who 'prescribes' me benzos once in a while convinced me to buy some good dope. Nice light brown rocks. So I got 0.5g, this was the exact deal that I had been chasing recently, when I wanted to try out IV heroin, before tapering out with bupe completely. So with this batch, I would put the water in the cooking pan first, and add a few grains of citric acid (tiny amounts, probably about 2-3 mg when using about 70 mg dope, a little more when more dope was used, but just a few grains of citric acid : 1 ml water gets the pH low fast!), and that had the acidity increase with a pH of around 3. Then I added the dope, stirred, heated, stirred, boiled, and drew it up into a 1 ml the syringe through a 10 μm filter. The total amount of solution each time was about 0.8-1 ml. I would then wait for the solution to cool in the syringe, and then get it ready to shoot. The few drops that came out when doing so I dumped on pH strips, which indicated that the final solution was back to about neutral. And each and every shot didn't sting at all and provided exactly the rush that it was supposed to.

So in short, if it works for you too, then why not adjust water pH first, then add dope, cook, and inject a solution where most heroin is dissolved and a neutral pH maintained, lessening vein corrosion.
 
^You should wait for the dope to cool before filtering in order to allow insolubles to precipitate out and get caught in the filter as opposed to your lungs.

As for acidifying the water first, it makes no sense unless you know exactly how many mols of dope are going to be added and even then why not just do it after? The fact that it came out at neutral was just luck. Add the dope then just neutralize with acid if you want a neutral solution.
 
^You always come up with such decent answers to my issues of confusion. Thank you.

And a lot of what you say is stuff that I would rationally come to if I actually took the time to think it through properly before posting.

In any case, had a nice run with the dope, minimal vein damage, and I am satisfied. So I am not going to go chasing dope again to try and make it better, or more optimal. For the time being, my itch has been settled. Which is exactly what I needed to be able to close my heroin abuse chapter in a decent manner and move on with my life.

Thanks again for your time and input, amapola. But with that said, I am still not done with this thread. I hope people with experience still come with some input, so that others might gain more knowledge on the matter, including myself.
