Yeah but why do that instead of just drizzling it down the throat. SL is not precise and I think it might work better than topical or well with topical but not better than oral min after a liver pass. That's the whole point--avoid the bloodstream and have it processed via the liver. The stuff tastes nastier the longer, it's in your mouth, that's what she said.exactly, I put .25ml under my tongue with a small syringe, and after 1.5 min. I spit it out, anyway if I swallowed it, and if it works, then more than half should've been absorbed sublingually. Then I just wait to drink water for like 10 minutes.
