LONGECITY

Putting rapamycin, even the uncrushed tablets, inside an enteric capsule allows the rapamycin to skip being disintegrated with stomach acids. That could increase the amount of rapamycin that is your absorbed dose. An enteric capsule is a special kind of pill capsule that omits dissolving at the stomach but that does dissolve at the small intestine.

Aliexpress . com has #1 (.5Gram) sized enteric capsules, 1000 for $11.88, that is a larger volume capsule than the enteric capsules at Amazon, $11.99/500 #0 capsules.

Bing Copilot says rapamycin is degraded with stomach acids.

I hope this doubles your absorbed dose of rapamycin, and doubles your rapamycin heightened longevity.

Putting supplements and molecules in enteric capsules is well known, but I only started doing it around when I got to be around 1/2 a century of age. 

Improvements to putting rapamycin, or MDMA in enteric capsules include:

Add piperine. piperine enhances physiological absorption of many molecules and supplements. Piperine powder is on ebay. Or like me you might already have a supplement like curcurmin or magnesium glycine taurinate that comes with piperine. Consider grinding some of these up and putting them in the capsule with the rapamycin.

Note, if you are taking regular rapamycin pharmaceutical pills: I read these pills often have an enteric coating, so omit crushing up pharmacy rapamycin pills, just pop them into the huge #1 enteric capsules.

If this works, then wouldn't people have to worry about overdosing on rapamycin (or other supplements)?

BTW, #0 caps are larger than #1, the next larger is #00 so if your #1 is .5gm the #0 is going to be more, perhaps .75gm
