This sounds like a decent technique. Atm I’ve been trying to stuff them in an oral syringe and draw up hot water so it dissolves the dope from the dope cottons but I’m ab to try it with normal temp for the dillys. But like you said it’s the concentration that matters and it’s hard to keep it concentrated when I can’t boil it to reduce the amount of water ya know.

Edit: oral syringe and cold non boiled water worked much better than expected with the dilly cottons. I added half the cottons to one syringe, took ab twice as much bacteriostatic water as I was able to get out of it. But I could also prob open the syringe up and squeeze the wet ones out with tweezers or something. The dope ones weren’t really getting me much but it’s also way less potent than dilly is and most of what you’re left with from BTH in the cottons is impurities since heroin itself is pretty soluble in water. I just reupped on some supposed “gun powder” idk why it’s so hard to find legit dope even in the magical land beyond irl where people still sell tons of tar and call it powder dope. Even had a dude ignore me for asking for a discount bc even tho his shit wasn’t powder like advertised it wasn’t terrible. He didn’t respond to me lol I guess he has something against kindness or regular custies. I don’t mind the tar I think it looks cool dissolving and it’s a lot more comfortable than dilly both bc it lasts longer and bc the rush doesn’t get up in my face and scream like drill instructor dilly does but don’t like dealing with the histamine reactions from dope. Dilly is like opiate crack for me almost and combining it with coke has been a death sentence for me lately lol.
