One of the clinics located on Roatan Island, Minicircle, offers a therapy called 'follistatin gene therapy.' This therapy, which is considered illegal in the U.S., involves injecting DNA molecules into individuals to encourage their bodies to repair themselves. The effects of this therapy are claimed to last one or two years, and the therapy costs $25,000. Follistatin is a protein that helps regulate metabolism, promotes muscle growth and development, regulates bone health, and plays a role in the regulation of various body functions, including the reproductive system. The therapy is claimed to 'increase lean body mass, reduce fat, reduce inflammation, extend telomeres, and significantly reverse epigenetic aging.' Whether the therapy is effective is tested using an 'aging test' developed by the same company. In 2024, it was claimed that the aging rate of a person who received this treatment had dropped to 0.64, meaning that, compared to someone who ages in 12 months, they would age in 19 months instead. However, it's worth noting that this therapy has only completed Phase I clinical trials, meaning the necessary studies for legal approval are still lacking.
