As far as I understand, any PH which is simply a powder stuffed into a pill and ingested orally can be taken in straight powder form. Of course, when you are dealing with small amounts, a pill will help regulate dosages. If you wanted to go oral on 1-test, you would use the 1-test THP ether instead of base dissolved an oil (usually sesame) and that could be ingested orally. However, the feedback with this method isn't as positive as with the transdermal.
The only thing I am considering is if a normal gelatin capsule helps prevent some of the destruction through the first-pass of the liver. I don't think it would, but if someone else knows, feel free.
