I’ve been looking for a fairly painless/ smooth test suspension (water based, not oil). I managed to have a good source a few years ago that would draw thru a slin pin and pin thru one as well.
If anyone here carries it in 100mg, at not a super silly price let me know please. Gear church used to carry it but I don’t see it any longer.
Hell, I’d even try homebrewing it up if I could get a recipe
