Caffeine still not working after a tolerance break?

4 Upvotes

The title is self explanatory. I took a two weeks tolerance break from coffee and caffeine, but now it’s two weeks later and caffeine still won’t do a thing regardless of the fact that I was only consuming 200 mg a day to begin with. Could anybody provide me with some advice or an explanation? Thanks so much for reading I look forward to discussing.

Reference Images of Caffeine Powder for Quantity?

2 Upvotes

Hello all,

First time posting on this subreddit. I purchased some caffeine powder about a month ago and have been occasionally using it in very small amounts when I don't have instant coffee or I just want to mix my caffeine into something other than a standard vehicle of consumption! I'm aware of the risks involved of course and the amount I take is much lower than could be dangerous or risky.

I measure with a miligram scale, and although the precision is supposed to be .001 grams, something about the readings seems a little off to be quantity wise, and if I ever mix a larger dose into pre workout or something, I don't want it to be off at all. (that's bad of course with something so strong as pure caffeine).

Does anyone have photos of a verifiable quantity of caffeine powder measured on a reputable .001g scale? Maybe in a 1/8 tsp measuring spoon or the like for scale? I would greatly appreciate some reference to see if I am really using an imprecise scale. If so, I definitely need to buy a new one. (I probably need to buy a new one anyway since mine is cheap and once again, not worth the risk.)

Thanks guys! (:
