The FDA has approved an auto-injector formulation of
testosterone enanthate (Xyosted – Antares Pharma) for
once-weekly subcutaneous self-administration in adult

absence of endogenous testosterone. It is the first subcutaneous
formulation of testosterone to be approved by
the FDA. Xyosted is contraindicated for treatment of low
testosterone levels associated with aging.
