Circulatory Dispense System

The MED/Star Circulatory Dispense System, or CDS is a cyber-ware component that links into the spine to control strategically placed micro-pumps in the body. This device is almost always installed alongside the MED/Star Endocrine Control System. One wonders why both devices aren't combined into one unit but that's because they both serve different purposes.
The CDS main control unit is located behind the heart and injects a number of substances directly into the heart right before the blood leaves the aortic valve on it's journey through the body. This allows the blood to have all the oxygen it needs while passing through the heart as well as the substances being injected. The added hormones do make the blood thicker, so the pumps that are installed alongside the control unit allow for the blood and hormones to be moved around the body much quick than can normally be achieved by the heart without causing any damage to the arteries and veins. The pumps allow the heart to pump normally while virtually eliminating the risk of blown veins, heart failure or strokes and aneurysms.
Despite being called a "dispense system", that is only one of it's functions although basically the main one. The CDS is controlled by the cranial microprocessor in a person which gives it commands on what hormones to synthesize. It does this one of two ways: It will either take hormones directly from the endocrine glands, which the help of the Endocrine Control System, or it will synthesize them itself in much the same way the endocrine system does. The dispenser has limited storage capacity, so it can only synthesize so much at any given time however the amount it can hold is generally more than the body generates or uses at any time they're required, so there's usually enough for multiple uses however doing so could risk damage to organs or other parts of the body.
The MS-CDS is one of the more expensive pieces of Cyberware to have installed and while some small circles have called for it's banning for civilian use, it does have medical applications such as dispensing hormones that the brain either can't or won't properly create on it's own. It can be used to regulate depression, manic behaviors, a myriad mental disorders, and can help with things like regulating sleep without having to take additives. It's incredibly effective for managing moods and other hormonal imbalances.
The military applications allow for the synthesis of hormones to sharpen focus, stay alert and be more sensitive to certain types of stimuli. Some people even use the CDS to flood their bodies with Adrenaline, causing them to enter a state of extreme aggression and physical strength. This process, which has been named the "Titan Systemic Response" allows the user to perform acts of extreme violence and exertion for a short period of time, lasting no more than about 15 seconds. Using the TSR can cause permanent damage to the heart, so the Endocrine Control System will purge the system of all of the excess adrenaline and returning the body to a baseline level, which then concentrates it in the stomach and the user generally throws it all up afterward. The CDS will then, with instructions automatically passed to it from the ECS, will then help the ECS dispense other hormones in the blood and around the body to quickly bring the body down to a normalized, rested state. It isn't uncommon to see people collapse after using the TSR as the body just basically resets itself after use.
