Yet to indulge and take some...
If you do then please do it right and collect some hard data.
1) Fast for 6h before, drink only unsweetened water.
2) Take a photo of your pupil after being 1 minute in bright light (without the flash)
3) If you have a glucometer (or know a diabetic that has one) then measure your blood sugar right before consumption.
4) Weigh 1.5mg of the crystal per 1kg of your body weight (0.68mg/lbs)
5) Dissolve the crystal completely in pure water and consume
6) Throughout the trip don't eat and drink only unsweetened water with some kitchen salt added (don't add so much that it becomes yucky to you). Note how much you drank.
7) Note the come up time
8 ) Retake a photo of your pupil after being 1 minute in the same bright light as in pt.2 (without the flash)
9) Measure your blood sugar again and note the time.
10) Write down your objective effects (locked jaw, eye wiggles, temperature, pulse, bowel movements, urination, etc...)
11) Note the time of your peaking.
12) Retake a photo of your pupil after being 1 minute in the same bright light as in pt.2 (without the flash)
13) Measure your blood sugar again and note the time.
14) Write down your subjective effects (energy, fast music appreciation, sociability, empathy, tactile sensations, etc...)
15) Write down your objective effects (locked jaw, eye wiggles, temperature, pulse, bowel movements, urination, etc...)
16) Note the comedown time
17) Note hangover time if any.
Report but do not post pictures of your eyes. Just measure the relative pupil dilation. Tell us what other drugs you had and when.
Note:
Don't throw the remainder away if it turns out to be crap ! Save it for testing later.
