Seemingly not an attractive choice is it but most people learned to take in all in stride as long as you weren't too blatant about it.
Most people during WWII had to make do with semi-purified fungus excrements (aka penicillin) injected into them.
An unlucky few got the penicillin extracted (sic) from the urine of men with VD at the Marine Hospital on Staten island who had just received penicillin.
From 40 to 60% of the original penicillin injected into us, leaves in our urine four hours later, completely unharmed.
The extraction was supposedly very simple, according to Dr LH Sophian, admittedly a very well regarded medical scientist.
(Basically making the urine even more acid by adding very strong HCL acid and then adding some acetone and chilling the mix in a fridge for 4 hours and then separating penicillin from acetone into water) and yielded up to 30% of the 40%-60% excreted.
That is 12% to 18% of the original penicillin.
But I doubt that the result could have been as pure as the original penicillin, itself already pretty impure.
Because if the result was at all pure, given such a supposedly easy extraction method, all the Allies' wartime drug industry would be busy extracting penicillin this way, on a commercial basis.
And very odd, when for 20 years the world's doctors and scientists were united in being repulsed by the mere thought of injecting natural fungus piss into humans, they said nothing about the idea of injecting VD filled "piss penicillin" into the same human veins...
