4 ho met fum vs hcl

[Magickduck]

So I am planning on taking some 4 ho met With some friendd this weekend and just found out we have the fumarate salt and well I hear its less potent and we would like to have visuals. We were going to take 15mg. Should we aim for 25 instead

Fumarate is about 75% as potent as HCl, increase your dosage by around 33% to compensate. 15mg HCl is about equal to 20mg of fumarate.

On erowid, are the doses for HCl?
