When SCP-5503-1 is consumed according to the package instructions, users experience an elevated sense of optimism and confidence. If, from the fourth day, the user proceeds to complete the full course of SCP-5503-2, the anomalous effects of SCP-5503-1 will be neutralised and their mood will return to baseline.

Should a person continue to use SCP-5503-1 beyond the recommended 3 day period, or fail to take SCP-5503-2, the effects will continue to escalate. The user will become simultaneously more confident in their own capacities, and less able to perceive potential risks. They will also express a growing desire to have an enjoyable time at the expense of completing necessary tasks or working towards long term goals.

Discovery: SCP-5503 was first discovered following a series of high profile deaths in the Devonshire area when a significant increase in unusual deaths was reported over a two month period. Incidents included jumps from rooftops, vehicular accidents, and a mass drowning. The sole survivor of the drowning incident, Ms. Mia Price, was interviewed by Field Agent Amy Worthing1.

Packages of SCP-5503 were found in 88% of the victim's homes, including that of Ms. Price and the drowned individuals. In 90% of cases, SCP-5503-2 was unopened. A general product recall notice was issued throughout the region and remaining stocks of SCP-5503 were taken into Foundation custody.

To test the effects of SCP-5503-1 in a controlled environment, a daily dose was administered to D-42451,2 to be continued for a period of 30 days. The behaviour and mood of the test subject was to be monitored via interview and observation. Prior to commencement, D-42451 had no history of depression and displayed a mood consistent with their current situation.
