Warp: We don't know why Dr. Urano said he favored the "small molecule" method over injections. Posgost over on yahoo said it is about saving money for his Lab. Apparently, manufactured MANF to be injected is expensive and so Posgost speculated his preference for the "small molecule" method was only "for the moment." Plus, the "small molecule" method has a higher probability of toxicity than recombinant MANF.

I doubt a few injections per year would be a stopper.

I would discount anything Fibonacci has speculated on. Posgost said he tweeted to him about a scientific mistake he made about LymPro. Shortly thereafter Fibonacci deleted all his prior tweets.
