This is a bad typo, and is being fixed. You have our sincerest apologies.
Holy cats!
So I've worked this out multiple times on different threads for 10 g of Form in one 8 oz bottle of Penetrate.
Before when we thought it was .5 ml per pump, it would take 5 pumps to get ~104 mg of Form (100 mg being the recommended dose twice a day(.
Now, 1 pump = 5 ml.
10 g Form / 8 oz Pen = 10,000 mg / 240 ml = 41.67 mg / ml
OR
208.33 mg / 5ml = 208.33 mg / Pump
So the recommendation is a half pump twice daily (assuming you can get all 10 g to dissolve)? Maybe I should only try dissolving 5 g and just pick up another bottle of Penetrate...
------------------
As far as amount per pump, I'm not sure if you meant the amount of Form per pump or the amount of Penetrate per pump. Either way the variations in density are going to be pretty small and the air pressure surrounding is going to be pretty constant too (local air pressure doesn't fluctuate extremely at that scale). I haven't used the bottle yet, but most pumps keep fluid inside the tube no matter how much is remaining in the bottle. So you'll be pumping relatively equal amounts of everything as long as you make sure that you keep the density constant(through shaking before pumping). If you don't do that, then the next time you pump you will bring in a different density of Form/Penetrate.
Then you will have a different amount of Form in the next pump.
Either way, physics or not, I think the moral of the story is make sure all of your Form is dissolved and shake often!
