filtering androsprays

[VanillaGorilla]

Does anyone know how biotest and ergo pharm filtered androsol and andro spray. Ergo was filter bed processed. Biotest made a big deal out of how androsol was filtered and made it sound like it was top secret or something. Anyone have any information on this and how you would go about doing it?

The only reason for filtering is to remove solids. There will always be a small percentage of solids present due to impurities in your powders. But who cares? The alchohol will kill any organics and your skin acts as a natural filter preventing the absorption of solids of any magnitude.
