The question “How much GHB should I take?” comes up very frequently on this sub. The answer is tricky, because you have to know what you have.

Gamma Hydroxybutyrate (GHB) is a salt that is occasionally found in its solid form, but almost always sold as a solution in water. Its prodrugs Gamma Butyrolactone (GBL) and 1,4-Butanediol (BDO) are natural liquids.

The problem with the question is that many people do not know what they actually have. Frequently, GBL and BDO are sold as GHB. Because they are liquids, you can give an accurate dose in milliliters because unless the are sold diluted by a dishonest vendor, the dose effects are consistent. Giving an accurate dose in milliliters for GHB, on the other hand, is impossible if you do not know the concentration of your solution. Most often, it’s around .9g/ml but this is not a given.

If you do not know what you have or what the concentration of your GHB solution is, no one can give you a dose that is accurate and safe. The only way to find your dose is to start with a low dose like 1ml or even .5ml and work your way up until you find your personal sweet spot — remember the harm reduction mantra: start low, go slow. The dose response curve for G is steep and not linear, the difference of .25ml can be large than you’d think, so take small increases.

What about redosing? The rule is not more than half your original dose, not less than 90 minutes later.

Used wisely, G is one of the best sex drugs there is. Used carelessly, it can lead to unconsciousness that puts an end to your sexy time.
