Ok
Also I have a tek for anyone who want help about measuring and dosing.
This is an example, let's say you want to dose 5 blotters of 25X-NBOMe with 200µg (assuming it's an example) so :
Determine the number of tabs on the blotter sheet - The perfing schedule (number of tabs per sheet) will allow you to know the number of doses per sheet. Let's assume that that you want dose 5 25X-NBOMe blotters (regular blotter like LSD).
Determine the retention volume of the blotters - The retention volume is the amount of liquid that can be supported by the absorptive properties of the blotters against the force of gravity. The process uses the chosen solvent (most often distilled water and alcohol, 37% alcohol would do the job too). The DRY blotter tabs are weighed (generally requires a balance with 0.01 / 0.001 gram sensitivity). This blotters are then over-saturated with the desired solvent for about 5 minutes, then picked up by a corner and allowed to drip off the excess solvent for about 30-60 seconds (when solvent drips occur a few seconds apart), and the thoroughly soaked blotters are then weighed again. The difference between the two weights (After-Before) is the weight of solvent retained. Let's assume for example that the sheet retained 12 grams (12ml) of solvent.
Selecting the desired dosage - Choose the dosage that you want each tab to deliver. For this example let's assume that we want 200ug of 25X-NBOMe whatever for each tab.
(Note: From this point forward proper safety equipment [gloves, safety glasses, and respirator] can be usefull).
Making the soaking solution - The blotters soaking solution needs to have 200ug per tabs ~ (dose) x 5 (number of blotters) x 1.03 = 1,30mg of 25X-NBOMe (the 1.03 factor is for the 3% excess, midway between 2% and 4% ) and this needs to be dissolved in 12 ml x 1.03 = 12,36 grams (ml) of pure solvent (distilled water or again alchool) (again, 1.03 is for the 3% excess). We dissolve the NBOMe in the solvent with stirring until it is completely dissolved.
Soaking the blotter – Place the dry blotters in a ziplock plastic bag slightly larger than the blotters tab and slowly pour in the soaking solution, trying to distribute the solution over most of the blotters. After completing this then attempt to seal the bag in a way to limit the amount of air remaining. Allow to sit on a horizontal surface in the dark for about 5 minutes to distribute evenly.
Drying the blotters – Carefully remove the soaked blotters from the plastic bag and hold by the corner to allow excess solution to drip off the blotters and back into the bag. When the drip rate from the soaked blotter is one drop every few seconds place the wet blotter on a drying rack (consisting of plastic-headed pins stuck into a flat piece of wood), and put the assembly in a dark location (away from the sun and fluorescent lights) with good ventilation and allow to dry completely (several hours to a day, depending on air movement, temperature, and relative humidity).
OR THIS IS A SECOND PROCESS BUT NEEDS MORE ATTENTION
This alternative process is a highly accurate way to provide dosage on blotters, albeit requiring more effort for preparation. Most importantly, this process is suitable for all compounds, regardless of the D/R curves, since it does not suffer from problems related to the inhomogeneity of blotter material or the other issues mentioned above. This process requires the acquisition of at least one highly specialized piece of laboratory equipment, a brand-new variable volume (adjustable) micropipette (something in the range of 0-100ul or so) that uses disposable plastic tips. These are not too expensive. With the use of additional, even more highly specialized equipment the process can be sped up substantially, but that is not the purpose of this TEK.
The basic process is the placement of very small, but highly accurate, amounts of solution on each tab. The amount of solution dispensed is selected to not permit the total soaking of the tab, but rather to only soak the very center of the absorbent blotter tab. When done this way, using the proper equipment, the user can be quite certain that each tab contains the exact amount of material desired, to very high accuracy and reproducibility.
Determine the number of tabs on the blotter sheet - The perfing schedule (number of tabs per sheet) will allow you to know the number of doses per sheet. Let's assume that the perfing schedule provides 14x14 tabs, for a total of 196 tabs ^^
Determine the retention volume of the blotter sheet - The retention volume is the amount of liquid that can be supported by the absorptive properties of the sheet against the force of gravity. The process uses the chosen solvent (most often distilled water or again alcohol..). The DRY blotter sheet is weighed (generally requires a balance with 0.01 / 0.001 gram sensitivity). This blotter sheet is then over-saturated with the solvent for about 5 minutes, then picked up by a corner and allowed to drip off the excess solvent for about 30-60 seconds (when solvent drips occur a few seconds apart), and the thoroughly soaked blotter sheet is then weighed again. The difference between the two weights (After-Before) is the weight of solvent retained. Let's assume for this exercise that the sheet retained 30.80 grams of solvent. Since this is water, 1 gram is almost 1 ml, or, more exactly, 1 gram = 1/0.9975 = 1.0025 ml @ 23 degrees C (about 73F). See
http://www2.volstate.edu/CHEM/Density_of_Water.htm for the density of water at other temperatures. (BTW, the density of pure ethanol and various ethanolic solutions with water can be found here
http://en.wikipedia.org/wiki/Ethanol_(data_page) and the best data for acetone can be found here
http://en.wikipedia.org/wiki/Acetone, but it lacks variation of density with temperature).
Either calculate the tab “dispensed volume” limit – Divide the volume of solvent (30.80 grams) by the number of tabs in the sheet (196 for this example

) to get the maximum volume of solvent that can be absorbed per tab. So 30.80 / 196 = 0.157ml or 157ul. The dispensed volume should therefore be in the range of 20% to 35% of the saturation limit for the tab, or 31ul to 55ul. 40ul would seem about right.
Or
Determine the “dispensed volume” limit visually – Prepare 5ml of solvent (like previously said distilled water or alcohol) with a drop or two of food color added (assuming it dissolves. If not, there are many organic-soluble dyes that can be used for organic solvents. Select one of them.). Take your adjustable micropipette and set the dispensed volume to 10ul, fill the tip and dispense the 10ul onto the center of blotter tab, just touching the tab lightly during dispensing. Adjust the micropipette to dispense 15ul and repeat the process on a new blotter tab. Continue the process, increasing the dispensed volume in 5ul steps, until the spot starts approaching the perf edges. Allow all the spots to dry. Now examine the spots (looking at both sides of the blotter tab) and determine the dispensed volume that leaves a spot that has plenty of margin surrounding it and is not even close to the perfs. That is your maximum dispensed volume.
Preparing the solution for dispensing – We need to calculate the amount of compound to dissolve in the chosen solvent. Let’s assume that we decided that proper dispensed volume for the specific blotter tabs that we have is 40ul, and the solvent is distilled water. And let’s assume that you want to dose 200ug or whatever of your favorite NBOMe in each tab. So we need 196 (tabs) x 40ul x 1.03 (3% extra) x 0.9975 (density of water @ 23C) = 8.055 grams of water. Into this dissolve 196 (tabs) x 200ug x 1.03 (3% extra) / 0.99 (assuming that the compound is 99% pure for this example) = 40,78mg of compound. Remember, the solvent must completely dissolve all of the compound! I also recommend that you add a very small amount of food coloring to the solution or even .5ml alcohol.
Dispensing the solution onto the blotter tabs – The key for this portion of the process is to accurately dispense the 40ul of solution onto each tab, but making sure that each tab only gets one dispensing. This is the rationale for the small bit of food color added to the solution in the previous step – to help the user see that a tab (in both the wet and dry state) has been already been dispensed, and prevent the potential for “double dosing”. Take your adjustable micropipette and set the dispensed volume to 40ul, fill the tip and dispense the 40ul onto the center of blotter tab, just touching the tab lightly during dispensing. Repeat the process until all tabs have been dosed.
Drying the blotter – Put the blotter sheet into a dark location (away from the sun and fluorescent lights) with good ventilation and allow to dry completely (several hours to a day, depending on air movement, temperature, and relative humidity).
Consuming the blotter 1st method - Sublingual, Upper gum, cheeks
2nd method - Put blotter in some solvent again to release the chemicals in the solvent, then snort it or use nasal spray
3rd method - Plug in the ass
Enjoy and take care !
Hope it helps
Anyway the first method as previously mentionned should be the easiest to begin with !
