How do you measure your doses?

[gn2osis]

^ A measuring cup could EASILY be inaccurate. They're not
made for this kind of thing. Probably best to stick to the oral
syringe. All those I've seen are on the money. For the larger volumes, if you don't want to endlessly
count oral syringe squirts, kitchen supply stores might have something
more accurate. A FOAF has seen shot glasses that are marked on
the side on 5 mL increments, and he verified (with an oral syringe)
that his was pretty accurate.

Thanks. I noticed that the syringe is marked for both tsp and ml...
It appears to be more aimed toward the tsp usage. Anyway, it shows 2
tsp = 10ml, which is not exactly accurate, maybe this could have caused
some of the difference, although it seemed like more than that would
cause. I compared the 100ml from the measuring cup to another
measuring cup i found, and it showed about exactly 100ml for both. I
will try measuring out with the syringe again, in case I forgot to
count one or two or something. Thanks for the help.

edit: I measured again and this time it comes right to
100ml. I guess I lost count last time or something, which isn't
beyond reason as I came close to doing the same this time, even when
tallying it as I go

Cool! It's really good that you posted this, because I think it
shows just how easy it is to screw up measurements even when totally
clear-headed.

I really think that the big harm-reduction message is this:
Attempting to "boost" while intoxicated requires having a totally
straightforward system, which means either pre-measured boosters, or
something nearly foolproof like 1 mg/mL that is easily measured out.

If milligram scale were involved, one would be best off using a scale accurate to the milligram (0.001g) with a tolerance of 0.002g to measure a large amount of substance as to decrease the error per measurement. For example, measuring 150mg (+/-0.002g) of a samplehas less variation than a measurement of 15mg (+/-0.002g) of the sample with the sample tolerance.


The sample of 150mg can then be diluted to a solvent which it is soluble. In this case, ethanol works best because is readily available, cheap, no reactive, and digestible. If 150mg of sample RC were dilutedby direct addition to a volumetric flask and filled with EtOH to the calibration line of a 250mL volumetric flask, a solution with the concentration of 0.6mg per 1mL can be created (150mg RC sample/250mL ethanol). The flask should be swirled half-way during dilution and inverted 25 times with the stopper in place to completely homogenize the sol'n after complete addition of EtOH.


(An indirect method can be followed by dissolving the RC in a beaker and quantitatively transferring the contents to the volumetric flask, but this requires more skill and increases the risk of loosing some of the RC sample).


If a 20mg dose of RC is needed, 33.33mL of the prepared 0.6mg/mL sol'n can be dispensed via a 10mL graduated cylinder and administered in solution form. (20mg RC dose/(0.6mg/mL sol'n)=33.33mL sol'n)


Using a liquid separation with a 250.0mL (+/-0.06mL) volumetric flask and 10mL (+/-0.02mL) graduated cylinder reduces the variation in samples and deceases the chance of overdose.


The solution should be prepared with high purity EtOH (95.00%=190 proof drinking alcohol=everclear) and kept out of light/heat and exposure to air. It isn't recommended that the solution be evaporated as this increases the oxidation of some compounds; however, the sol'n can be absorbed into 'blotters' that have uniform absorbency for solid administration by taking the volume of sol'n added to the blotter and dividing by volume (Area can be assumed in some cases).

^ H2O may be better than ethanol for tryptamines b/c it can be frozen, thereby preventing degradation; cf search engine.<!--

[moracca]

I thought the dosage needed for these types of RC's was too large for blotters?

[allyourbase]

depends on the tryptamine really. frankly; the majority of them, in their pure form, are already perfectly suited for storage. tryptamines do not degrade save over LONG LONG times; the only exception to this being those with double bonded oxygen groupings, those never seem to last more than 6 months without refrigeration. as for weighing, DO IT WITH A SCALE!!!! if you MUST do liquid fractioning do it in a graduated cylinder, NOT A GODDAMNED MEASURING CUP FROM WALLS-MART.


also as to the blotter question; depends on the blotter papaer used, the kind they line desk drawers with can be up toa few mmthick, at that thickness you could easily get 12 mg into a square the size of a postage stamp.

if you were to do the method with vodka or what have you, how long
would it stay potent for? i wouldnt want to be doing like 20 doses in
20 days, you know?

[raven3davis]

SWIM finally got a scale, but he still likes to measure out doses by dissolving the poswer in liquid. It is so much easier to just weigh out 100mg or a gram and dilute, than to weigh each dose each time you want to take some. Its also a lot easier to measure a liquid dose when you are tripping. Ever try weighing out a dose while trippin? Its really hard!

[pinkfloyd2048]

If I were to choose over H20 and EtOH, I would choose EtOH because most RC's are more soluble in EtOH than H20 and the ionization present in H20 (even distilled) is enough to degrade the product over time. Unless you have DI (deionized) H2o, you would be best off on EtOH. As well for storage time, I would imagine up to 6-9months with a minimal amount of air (longer in freezer). Also, EtOH won't freeze, so liquid measurements can be made from the freezer insted of having to warm the solid RC/Ice mix (which can destablize the cmpd).

[moracca]

If the chemical was dissolved in EtOH, and the remainder after dosing was put into the freezer, how long can we assume this will keep, as opposed to H2O which can actually freeze? Will the EtOH not freezing have a big impact on stability? If it is dissolved in EtOH, how easy would it be to evap the salt back out and keep as powder form? Thanks
