Hello all, I'm new to the BL forum. Looking for information on how to purify or turn into a less harsh version of H. I have plenty of BTH but it just really hurts to use for any ROA. Especially nasal, IV, and IM I know you can do something on a stove with maybe water and some other chemical to boil, filter and let sit to harden up. I've been searching the web for almost 24 hours and can't find much. In the Wikipedia section about BTH it mentions boiling it in liquid medium on a kitchen stove and filtering to let it re-harden with no chemical knowledge this may be done. Well I can't find what the medium is? (Water?) and what to use to do this with (lactose?) shame to have a bunch but hurts so bad you only do enough not to get ill. Any links, or threads I may have missed someone may point me to? The quality of the BTH is good just way too harsh. Thank you for any and all insight/help. Because Deyknow!
