The Boris Pheromone

Description
The Boris Pheromone (also known as Pheromone A-12, or "Sarin 2.0") is an isolated, distilled pheromone from within Boris' immortal body extracted by some rogue members of the UWG (United World Governments) in an attempt to harness it's power to seduce female economics students. Unfortunately for them Pheromone A-12 has an unwanted side effect when isolated from Boris' other 11 pheromones; it causes a painful and oily death for all who inhale it.

History
In 1967 (also knows as the "summer of love") a group of rogue agents from the UWG were down on their luck with the ladies. That year, a powerful high-ranking agent from the UWG had managed to procure a tissue sample from the sole of Boris' right foot, and these agents ran tests on the sample in an undisclosed UWG lab.

They discovered that Boris' luck with the ladies (specifically economics students) was due to a pheromone that oozed from the sebaceous glands in his feet that they called "Pheromone A-12". Despite warnings from the higher-ups, these agents decided to isolate and replicate this pheromone into a serum that they could use to entice women.

Their efforts, at first, seemed to be a success; all three men were lavished with attention from ladies that wanted nothing more than to discuss gold prices. This came to an abrupt end, however, as the three men, as well as half of a university campus, abruptly swelled to the size of a DAF truck cab, before oozing diesel for three hours, and perishing.

Agents tasked with performing the post-mortems claim that isolating Pheromone A-12 from the other 11 pheromones present in Boris' immortal body caused the serum to become unstable, and their mortal bodies could not cope with the increased tar levels that come with harnessing Boris' power.

Pheromone A-12 has been labelled a "bio-weapon" by the United Nations, and the only remaining vial is being held deep in an underground bunker.

After fears surfaced that the Bogdanoff Twins may steal the serum and use it for nefarious purposes, Grichka publicly stated that the twins "did not need help getting the ladies" and boldly stated that the serum is "not actually a Boris pheromone" but rather just "a vial of piss".
