The Innsmouth Trading Company is very excited to reveal out latest acquisition!

From the estate of the late Dr. Herbert West we have acquired several cases of his patented “Health and Youth Reagent”. This fluorescent yellow-green liquid is extremely reactive to ultraviolet light, and is said to contain the secrets to life itself. The reagent comes packaged in clear, 16 oz. glass bottles; the labels -containing instructions for use and a list of potential side-effects- have naturally browned with age.
