Practical Examples of Making a Solution

One of the more frequently asked questions is how to take a powder and make a solution for convenient dosing. I have created 3 videos for your viewing pleasure:

  1. 1g compound to 50ml of PG - 20mg/ml Solution
  2. 500mg compound to 50ml of PEG-400 - 10mg/ml Solution
  3. 1g compound to 50ml of PEG-400 - 20mg/ml Solution

The videos show common variations on measuring, mixing, and storage. Each video description includes what items were used.

What to do if the compound does not mix fully (i.e. you're left with floating particles of compound in solution)?

  1. leave for 24 hours
  2. how water to outside of lidded bottle
  3. dilute solution

Why make a solution?

Easier and more accurate to dose.

Why not buy a premade solution?

There are many reputable vendors who sell premade solutions and it's always a valid option.

Making your own solution has two main benefits at the expense of convenience:

  1. Making your solution guarantees that your dose is accurate, or that at least you only have yourself to blame if you mess it up.
  2. Premade solutions are around ~3x more expensive per dose.

Are you aware that your dose isn't quite right? (And variations to this effect)

Agreed. I have tried to present this as simply as possible. While simply measuring 50mL of solvent and adding 500mg of solute introduces error (because adding the solid will change the final volume of the solution), it's a minor variation that does not concern most.
