Instructions for injecting users
You should test every time you inject. The easiest method is to test the residue from your spoon or cooker.
- After preparing your shot, set the needle aside and wait to inject.
- Add about 1ml (1/5th of a teaspoon) of clean water into the spoon or cooker.
Proceed to 'Testing your sample'.
