The Essendon Football Club supplements saga remains one of the most significant chapters in the history of Australian sports administration. Over the course of a multi-year investigation, the narrative centered heavily on the alleged use of various substances during the 2011 and 2012 seasons. As an observer of sports history and the evolution of performance-related supplementation, it is essential to look at the specific compounds that became synonymous with this period.
The Core Substances Under Scrutiny
Central to the investigation was the peptide known as Thymosin Beta-4 (often abbreviated as TB4 or Thymosin Beta 4 (TB-4)). For many following the developments in the media, this name became the primary focus. Thymosin beta-4 is a naturally occurring protein that plays a role in cell regeneration and repair. Throughout the proceedings, regulatory bodies alleged that this specific substance was administered in Essendon's training facility as part of a broader fitness program.
Another compound frequently cited in reports was AOD-9604. Originally developed as a modification to growth hormone, AOD-9604 became a focal point for investigators tracking the procurement processes of the time. The combination of Thymosin Beta 4 and AOD-9604 appeared repeatedly in documents that attempted to map out the substances allegedly sourced for the club.
Beyond the Headlines: Other Compounds Mentioned
While thymosin beta 4 and AOD-9604 dominated the headlines, the investigation into the club's broader supplements program revealed a wider list of substances.

There was also intense public speculation regarding whether other compounds were involved. For instance, there were discussions about whether the athletes were exposed to one from the family of growth-hormone-releasing p Dons' focus on use of horseracing peptide thymosin beta-4 eptides. In response to these rumors, internal club figures at the time, including Stephen Dank, were adamant, specifically stating that there was no GHRP-6 ever used at Essendon.

Conclusion
When analyzing what peptide was essendon using, it is clear that the investigation was not just about a single substance, but about a culture of experimental supplementation.
