The compound has no FDA approval and no active clinical development in the US — it has not been formally evaluated for human safety or efficacy.Most research peptides used in self-experimentation communities are Category 3. Category 3 status means the FDA has not evaluated the compound at all. This is not the same as "proven unsafe" — it means there is no systematically collected human safety data. The absence of evidence of harm is not evidence of absence of harm, particularly for long-term or high-dose use.
