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.
