Volumetric Dosing of LSD and Splitting LSD Doses

It is possible to simply cut a tab off LSD or LSD gel in half to get around half a dose. This isn’t an accurate way to split a dose, however, and will work poorly if you want to split doses into smaller portions, or need to split liquid LSD. The method below, volumetric dosing, is simple, and highly accurate.

Volumetric dosing of LSD is an accurate way to split LSD, regardless if in liquid, blotter, powder or gel form.  As LSD is a highly concentrated drug, diluting the LSD allows for more accurate division of doses.

Step 1.  Get your supplies.  You need a solvent, distilled water (not tap water), grain alcohol (Everclear) or vodka will work.   You need a liquid measuring device, such as an oral syringe, which can be obtained at most pharmacies or ordered online.  A 1 ml syringe works well. However, any accurate way of measuring liquid will work, including a shot glass.

NOTE:  Do not use tap water.  LSD is highly reactive to even very small amount of chlorine.  Stick with distilled water or alcohol. Other solvents will work, but do an Internet search to confirm non-reactivity with LSD. 

Step 2.   Accurately measure an amount of the solvent into a clean glass.  5 ml will likely work well. If you lack anything to measure liquid, you can still do this method in a pinch with any small container, such a shot glass or even something like a cap to a 2 liter bottle — see below for details.

Step 3.  Add a known amount of LSD and mix thoroughly.  For liquid, stirring for 10 seconds is fine.  If it is blotter, the blotter paper may remain in the solvent but work to dissolve it as much as you can, which may take a minute.  Mix shortly before taking (minutes not hours).

Step 4.  Determine the individual desired dose.  For example, individual A wants 100 ug and individual B wants 150 mg.

Step 5.  Do the math.  Take the amount of LSD added to the solvent and divide by the amount of solvent.

For example, if you added two drops of liquid LSD at a concentration of 125 ug per drop, this means you have added 250 ug of LSD to 5 ml of solvent.  Dividing 250 ug by 5 ml means each ml is 50 ug of LSD.  The person who want 100 ug takes 2 ml of the solution and the person who wants 150 ug takes 3 ml of the solution.  

Another example:   3 blotters of 150 ug LSD.  3 people, wanting 100 ug, 150 ug and 175 ug.  Dissolve 3 blotters (450 ug) LSD in 5 ml of solvent.  Divide 450 by 5 equaling 90 ug per mi.   First person takes 1.11 ml (100 ug/ 90 ug = 1.1), second person takes 1.66 ml (100 ug/ 150 ug), and third person takes 1.95.  You have 0.28 ml remaining, equaling 25 ug of LSD.  

If all you have is a shot glass, bottle cap top or similar small container, the process still works. You’ll just need to do some fractions. Figure out what portion of a dose you want to take. Let’s say you want to take 1/3 of a dose. Add three shots/caps of solvent into a glass, measuring slowly and carefully. Dissolve the LSD, and then take a single shot of the solution (1/3 of the solution).  

Note, do this shortly before ingestion. Even distilled water or grain alcohol will become reactive with LSD-25 over time. Be sure to also keep the solution out of direct sunlight, which will speed degrading of the LSD molecule while in solution. Don’t panic… a few hours in solution is unlikely to cause any harm, but don’t mix it up the night before.
