Dose - How much is the standard concentration of GHB solutions?

[sknkv2]

SWIM's hamburger is interested in trying GHB but is worried that it will be too hard to gauge the dose. Most people the hamburger has talked to take between 5-10 ml but this says nothing about GHB. So SWIM's hamburger is just wondering (even rough estimates are good) as to what the most frequently occurring concentration is (he lives in Melbourne if that helps).

It is extremely unwise for anybody to buy NaGHB from a third party. They would have no clue as to the purity or safety of the product, nor the true state of its dilution.

If, there being no other option, one were to procure NaGHB in liquid form from a third party then a safe and sensible route to take would be the following:

1)Test the pH of the solution to ensure that it is, at least, relatively pH neutral. It should, in fact, be slightly alkali. Somewhere in the region of 7.5 (although this depends on the pH of the water it was diluted with) is good.

2) Pour the liquid into a saucepan (any type will do as the substance is not GBL) and boil all the H2O off. The aim is to get the temp to 150c.

3) As the liquid is stirred it helps to release the H2O and, after a few minutes at 150c, there should only be light bubbling. Taking it off the heat and stirring it should show these bubbles to be getting smaller and less frequent until, once all the H2O has evaporated, stirring fails to elicit any bubbling.

4) With the saucepan now containing only molten NaGHB, it can be poured into a baking tray to harden and cool.

5) Once hardened this can then be broken up (grinding is not necessary and simply makes it absorb more moisture from the air) and weighed.

6) Weigh the amount required (it doesn't all have to be diluted at once) and place it in a measuring jug. Multiply the gram weight of the solid by five - this is the amount in ml's it should be topped up to with hot water in order to have a ratio of 1g of NaGHB to 5ml of water.

This might help too:

Almost all of the NaGHB SWIM sees around is very oily and thick having an high viscosity kinda like maple leaf syrup. This syrup type of NaGHB is what seems to be favourite among a lot of people SWIM knows.

SWIM made his own NaGHB and diluted to the recommended 1 gr - 5ml but this gives a very watery type of NaGHB.
Then SWIM diluted 4gr - 5 ml and this resembled the he syrup kind of NaGHB.

Does this mean that almost everyone SWIM knows is taking 4gr - 8gr (1 or 2 tubes each 5ml) of NaGHB ?

[MrG]

Not necessarily, it could be that what SWIY's associates have been purchasing was 1,4-Butanediol which is a viscous solution.

If they have been taking 4-8gr of NaGHB they *will* know it.

Unless they have a particularly strong tolerance for GHB they will likely fall asleep within half an hour of ingesting 4g. The Xyrem dose for sleep is 4.5g.

Anything much above 4.5g in a single dose is generally not considered safe.

If, however, they have been taking 1,4-BDO in the mistaken belief that it was NaGHB, they might want to seriously reconsider.

I'm almost certain swim's associates use NaGHB because swim took it once and felt near to nothing.

So thats why swim decided to make his own NaGHB a while ago according to your posted recipe in the chemistry forum.

Last night 9pm swim took 4gr (diluted in 10ml) of his own batch and felt some kinda drunk within half an hour (swim doesnt drink so he really doesnt know how drunk feels but it feels funny, dizzy, speak a bit slow) but did not fall asleep. At 9.35pm swim took another 2gr (diluted in 5ml) and felt a bit more drunk but could still call friends and think clear. Then around 10pm swim took another 2gr (so total dose was 8gr within 2 hours) and swim felt a sleep around 10.15pm and woke up at 02.30 am.

So according to this 'second experiment' (swim did the same last week and could stay awake with 3 doses of 2gr each within an hour) this would mean that swims sleeping dose is double the standard 4gr sleeping dose. Could this be possible or is there something else going on ?

Is it possible to have some sort of weak NaGHB which only acts on doubles doses ? If so could it be caused by 'bad' GBL or 'bad' NaOH ?

[porchy]

There is no type of weak NaGHB. SWIM thought that maybe his experiment when wrong when his singular dose hadn't produced an effect but that is not the case and the experiment has gone swimmingly (lol). Just dose up slowly until you find the amount that feels right, and an hour or so later take half as much as the first, just as a top-up. But remember not to over do it as one night SWIM woke up (4 hours into the GHB-induced sleep, surprise surprise) vomiting what he can only describe as savagely! Tip of the day - just take it slowly

Wonderful description of vomiting!

[MrG]

Is SWIY allowing at least two hours after eating before taking his first dose?

Stomach contents can seriously affect the absorption rate, particularly fatty foods.

THIS IS NOT THE CORRECT WAY TO PREPARE A SOLUTION!

If you want a 1g/5ml solution, add 1g to a graduated cylinder and add water until it reaches the 5ml mark. You will NOT be adding 5ml water, it will be a little less. This way a dosage of 5ml will contain 1g ghb.

So 10g GHB would need a total volume of 50ml solution, not 10g + 50ml water. Take the 10g, put it in a cylinder, add water until the total volume is 50ml.

	thanks for the info
	Thanks for the heads-up.

Thanks for the reminder, I'd forgotten about this thread.

SWIM's mind must have been on vacation when he first wrote about the dilution. He completely missed the fact that it needed to be made up to the mark with the solid already in. I'd already taken the liberty of correcting this on other threads but if you do see it repeated incorrectly anywhere else, feel free to highlight it.

D'oh!
