Theres 3 common acetylcholineesterase inhibitors, they are and dose;

Pyrostigmine (120mg/ed)
Galantamine (8-16mg/ed)
Huperzine A (50-150mcg/ed)

NOTICE, Huperzine A dosage is in the MICROgrams NOT MILLIgrams. If you took 50mg of Huperzine A you would DIE. But you can use any of the above, perhaps pyrostigmines better because thats what was proven effective in the clinical studies at that specific dosage. But all three of the above are acetylcholineesterase inhibiors and will thuis have the same inhibitory impact on somatostatin.
