To further help you should post:
The tek your using
The portions you used
Ideally you should be able to do subsequent pulls, but it can vary depending on the volume you used to pull the spice. Either way there is a point when the amount of DMT in the solvent reaches a saturation peak, at this point you have the most DMT you can get in the solvent, and it is an equilibrium between free base DMT and Dissolved DMT in the Solvent then you remove and freeze precipitate it.
Now if you managed to pull 2.3 to 2.5 grams of of DMT from a freeze precip of your NP solvent, then you already have some great yields of close to 1% on MHRB. This either means you have some impurities(excess lye/plant material) and may want to consider washing it and recrystalizing, or you did a damn good job.
When you remove the fully saturated solvent and replace it with new solvent you can establish a new equillibrium between the amount of DMT in the basified solution and the amount of DMT dissolved in your NP solvent. Think of it as diffusion, when solvent lacking solute enters the container the DMT will naturally move towards the area of lower concentration (NP Solvent) from the area of higher concentration (Basified bark solution), but there is less DMT available due to removing it from the extraction jar with your first pull. This means your subsequent pulls should be substantially smaller and smaller. 50 mg from second pull after 2.3-5 grams first pull sounds fine.
turning it upside down should not effect the yield precipitate but rather it helps drip fats and excess contaminates off of the crystals for full drying, and storing in a pill jar in freezer is plenty fine, my friend likes to use microcentrifuge tubes.
Sorry long winding and possibly convoluted post, over tired from studying for exams tomorrow, maybe will try and clean it up tomorrow
Need sleep
Hope it helped
I am here to restructure my priorities in a way to most benefit all
