Save your unusable raws Guaranteed.

After it crashes, I would remove as much ethanol as possible with a pipette or a syringe, this way any contamination remaining in the ethanol dosent make its way into the final product. Then evap the the remaining residual ethanol or water

I may have removed too much ethanol at step (3)

it's now turning into a complete block in my freezer.
20g in 50ml (total)
Should i add water?


There's something weird about this, it ended up leaving adhesive tape-like stains all over my beakers which im having a hard time removing. Hot water + soap + scrubbing doesn't remove it at all. The stains have the same strong chemical smell as the raws (which is a plus i guess).

Boiling water got rid of it lol

Yeah it probably the testosterone with the impurities leaving the stain. Due to the high melting point its really difficult to remove. With test c, I had to use boiling water to clean it up. Acetone or IPA works well also.

If its cold, dont add water until you drain off the raws. If you add it to the ethanol, everything will just turn into a slushy or a block if ice. I just use the water rinse to clean the remaining solvent off before the vacuum chamber.

That's some serious contamination right there... if it dosent clean up, maybe do 2 re-x's, one with EA/heptane and ethanol on the second. This way you cover all bases for polar and non polar contamination

Its 86% TRE not test
