I have just been weighing out .1 on my digital and splitting it into 2 piles so I figure roughly 50 mg. I am thinking it's legit because after a week or so my joints start aching pretty bad during my workout.
Yeah when I did the math I was like "holy shit" they sent me a ton of that shit, been thinking about attempting oil based winny but i've heard too many bad things about it.
Idk how close you want to be, but a scale that measures to .1g is no good for anything that's dosed in milligrams unless you're weighing a lot of it, then dissolving it in something, and dividing that solution by volume or weight.
The problem is that the margin of error due to "significant digits" is very high. For example, if you had a scale that measured to the gram, you wouldn't know if you had 1.0 or 1.9 grams, only that you had neither 0g nor 2g.
This problem becomes more serious when the dose is in milligrams, as compounds dosed in mg tend to be fairly strong. You could be getting double the dose.

Basically, to get a reasonably close tenth of a gram, your scale would have to be precise to at least one decimal place beyond tenths.
If you weigh out ten grams, that is, 10.0, then you could divide that up with greater precision in the manner outlined above.
Not trying to be a dick, just don't like seeing people get hurt.
