I signed up to post this, I put a Methyl B12 5000 sublingual from Now Foods (warning: contains folic acid, do not use if sensitive to it! - I used that because it's the only one I had on hand) inside a folded napkin, smashed it a bit with a meat hammer, put the powder inside a small tea cup and mixed it there with a rather small amount of moisturizing cream, applied that on both arms, spread it around and then waited.
The result was much, much better than a sublingual usage (even upper lip) came slower than a sublingual would, lasted for hours (I think) and as intensity is concerned, it was much "stronger" than keeping it under the upper lip for one hour - and it didn't burn my gums.
I judge the intensity based on a very specific sensation that I have in my lower legs when methylcobalamin is "working", it's like tiny electrical discharges above the ankle area. That came at about one hour after applying the cream, followed by generally more muscle strength. I had some other energy bursts a few hours later.
I have to mention that at this point I had _zero_ effect from using those pills as they were intended, even if I was keeping them for 1+ hours in my mouth, however this worked for me, I'm gonna try it with Enzy but I don't have them on hand.
The cream I used was Oriflame Essentials Moisturizer Concentrate, it has the following ingredients, I don't know if it matters, I chose it simply because I had it around the house, for no other reason:
AQUA, PARAFFINUM LIQUIDUM, GLYCERIN, PETROLATUM, BUTYLENE GLYCOL, DIMETHICONE, PEG-2 STEARATE, BUTYROSPERMUM PARKII BUTTER, CETYL ALCOHOL, CARBOMER, PHENOXYETHANOL, POTASSIUM CETYL PHOSPHATE, IMIDAZOLIDINYL UREA, PARFUM, SODIUM HYDROXIDE, METHYLPARABEN, PROPYLPARABEN, NIACINAMIDE, ETHYLPARABEN, SODIUM STARCH OCTENYLSUCCINATE, CALCIUM PANTOTHENATE, MALTODEXTRIN, SODIUM ASCORBYL PHOSPHATE, PYRIDOXINE HCL, TOCOPHERYL ACETATE, SILICA
The light pink powder turns much brighter and darker when mixed and the result might contain small clumps that come from whatever else is in the pill that keeps it together, it's some sort of membrane but if you can ignore that, this is the best bang/buck/pill I ever got in terms of both strength and duration.
I think b12 is water soluble so it should work with anything that has water and is supposed to be absorbed by the skin.
Will report back, since this is just my 2nd day of doing this. Another patient tried it (didn't know about the upper lip method) and reported a state of mental clarity never achieved before by using the tablets under the tongue.
It's not pretty, it just works.
