Neuropozyne

Neuropozyne, informally called No-Poz or Nu-Poz, is a drug used by the mechanically augmented. It helps prevent neuroprosthesis rejection syndrome, a build-up of scar tissue that blocks electrical signals between augmentation electrodes and human tissue, ultimately resulting in rejection. It was created by Darrow Industries and is now manufactured exclusively by VersaLife.

Medical uses
Mechanical augmentations are sophisticated pieces of machinery that require a human-machine interface to function, as designed. The standard design is Darrow Industries' PEDOT-cluster array, where polymer electrodes bridge augs and the host's neurons, acting as a neuroprosthetic junction. PEDOT clusters connect to a biochip, which in turn interfaces with the host's brain directly. Unlike conventional, non-cybernetic implants, the invasive nature of the augmentations causes the body to identify them as a foreign object and triggers an immune response: Glial tissue begins to form around PEDOT clusters, leading to what's best described as nerve scars. The glial tissue buildup eventually shuts the augs down and culminates in an extremely dangerous implant rejection, identified as the Darrow Deficiency Syndrome. Neuropozyne is a drug developed to control the body's rejection response, breakind down glial tissue build-ups and preventing further build up of the tissue until Neuropozyne is metabolized. A standard dose is enough for one week of protection.

Neuropozyne is typically delivered through injection, and delivered in 20 ml vials containing 10 000 mcg of the drug. A standard package contains nine vials, securely packed together. Single vials may also be stored and delivered in protective "bottles", and such method of transportation became standard outside clinics and bulk packages by 2029. The actual dose needs to be tailored to each augmented person, depending on their gender and weight class (i.e. amount of augmentations).

In rare cases, augmented humans may exhibit a resistance to Neuropozyne, requiring higher dosage and imposing higher costs. Adam Jensen, a genetically engineered superhuman, was on the other end of the spectrum, as he was modified in utero so that his body would accept augmentation without the need for Neuropozyne.

History
Neuropozyne was created by Darrow Industries, in order to address the aforementioned rejection syndrome, made more severe in the wake of the PEDOT revolution ushered in around 2010. Darrow sold his exclusive patent for Neuropozyne to Bob Page's VersaLife in 2020, which used its monopoly to turn Neuropozyne a multi-billion dollar source of revenue. As Neuropozyne was not manufactured using rare chemicals, the monopoly was upheld by strictly monitoring distribution and jealously protecting trade secrets surrounding its synthesis.

2027
Exploiting the fact that augmented humans were reliant on Neuropozyne, VersaLife artificially inflated prices and reduced availability, engineering a shortage of Neuropozyne. VersaLife claimed that this was due to various setbacks it has experienced. During this shortage, a competitor drug known as Riezene emerged. Given that Riezene, like Neuropozyne, was produced by the Illuminati using Zaaphire Biotech as a front, it was most likely artificial. The high price of Neuropozyne drove some people to experiment with Riezene, despite no proof of its safety, while others moved to acquire it by illegal means. Sarif Industries employees Brian Tindall and Tim Carella even stole Neuropozyne from the company's Detroit labs, to distribute it for free to people who could not afford it.

To further increase its role in corraling and limiting augmentation, Neuropozyne remained a controlled substance available via prescription only, and a single dose was effective only for a week, necessitating frequent purchases. Even global pop stars, like Ny'ashia Akim, noted how expensive it was.

Sarif Industries attempted to break VersaLife's stranglehold and usher in a new era of mechanical augmentation thanks to Megan Reed's research, based on Adam Jensen's DNA. Sarif's security chief was hired partially due to his unique genetic makeup. If turned into a gene therapy, could have unlocked access to augmentation for any human beeing at a drastically lower cost and virtually perfect safety, by replacing neuropozyne with adaptive DNA fusing that would make the host accept augmentation like Jenses did. This democratization of augmentation was viewed as a potential danger for the Illuminati, who used anti-augmentation movements such as Humanity Front and Purity First to campaign for tight regulation and banning of augmentation. Facing a real risk of Sarif succeeding, the Illuminati decided to forgo soft power in favor of hard: The Tyrants were sent to attack Sarif Industries and abduct Reed and her team, on the eve of the historic hearings. The plan largely succeeded, and VersaLife maintained its position and revenue.

2029
The Aug Incident triggered by Darrow had more lasting consequences, destroying the momentum behind human augmentation and controlled evolution, and played right into the plans of the Illuminati. After the closure of LIMB clinics, Neuropozyne became strictly rationed and even more expensive, driving even greater profits to Page's VersaLife. By 2029, access was so restricted that poorer augs had to rely on free clinics and charitable services of the Augmented Rights Coalition or black market sources. Some fixers even refused to trade in anything but vials of neuropozyne, with surplus vials purchased by dealers at prices starting with 1000 credits per.

In places such as Útulek Complex, where the augmented are sent to live in isolation, the police force has control of the Neuropozyne supply, and thus of the people that live there. Such degree of control inevitably leads to tension and social unrest: During a hostage situation in Dresden, Germany, one of the demands made by the augmented terrorists responsible was for a generic form of Neuropozyne to be produced. This would result in the drug becoming much cheaper as VersaLife would no longer hold a monopoly over it. However the situation is resolved without the demand being met.
