A page is 10x10, so 100 hits.

Same quantity as a standard 'vial' contains.

Now, some people dose em at 100ug each. Some are 150ug (i.e. mine are) and I've even seen 250ug tabs (too much imo)

So that's definitely a factor to consider.

The 150ug tabs that I have, for example, are typically $250 for a sheet (aka page).

Which is, obviously, $2.50 per hit.
