here go down to DPMG (dipropylene glycol) im sure its not cheaper then this...
as for the Phera plex or SD being made into a trans, well technically yes it can if the molecules are small enough. BUT you dont want to... they are both methylated giving it nearly 100% absorption through the liver on first pass, by taking it transdermally youd lose over 50% of the compound and it would be an utter waste of the compound and penetrate transdermal solution.... this is the whole reason these compounds ARE methylated, to make taking them orally the most effective route, other then injecting them.... then you still lose some through the conversion process to strip it from the fillers, so its still prob better to ingest it.
PEG won't increase bio-availability. Just used to keep chemical dispersed in solution. If you are planning to uncap Pher-Plex or Superdrol and place in solution this will be a waste of time. If you find bulk powders then placing it in solution will be helpful.
