In animal-model work, NNMT inhibition with 5-Amino-1MQ has been associated with changes in adipose-tissue mass, in NAD+ pool sizes (because NNMT consumes nicotinamide that would otherwise feed the NAD+ salvage pathway), and in methyl-donor dynamics (because NNMT consumes S-adenosylmethionine)

Oral tablets, especially with absorption issues, offer much lower and more variable bioavailability, working more slowly

Smaller injection volumes at higher doses
