With the powder of tempol how much is 20 mgs? Did you mix it with water?
When I bought my tempol from
http://tempol.info, they sent me a really tiny plastic scoop to pick up the powder — when I say tiny, I mean the scoop spoon was only about 3 mm across. I found that three heaped scoops was around 20 mg of tempol powder.
If you want get precise, for around $5 to $10 you can buy a
digital scales on eBay that weighs down to just 1 mg, and with that it is easy to measure tiny quantities like 20 mg.
The dose range for tempol is 10 mg to 100 mg daily. I chose 20 mg daily for no particular reason, apart from the fact that lower doses are more economical.
You take tempol sublingually: just put the powder under your tongue. It seems to melt into the mucous membranes of the mouth almost instantly. No need to mix with water.
Tempol comes as a bright orange power in a small glass bottle, and is heat and light sensitive, so must be stored in the fridge. If it ever loses its bright orange color, then that is an indication it has been heat damaged. But kept in the fridge, it is very stable, and will last indefinitely.
If you buy a gram of tempol, then at 20 mg daily, it will last for 50 days.
