Pentadeca Arginate (PDA)
No lawful US pathway
01 · Overview
Pentadeca Arginate (PDA) is a name used by compounding pharmacies and peptide suppliers for a synthetic 15-amino acid peptide, commonly marketed as a variant related to BPC-157. Its exact structure, salt form, and relationship to other peptides have not been described in peer-reviewed literature.
Claimed tissue repair properties are extrapolated from marketing materials and from research on related peptides rather than from studies of PDA itself.
02 · Research summary & key findings
A search of PubMed identified no peer-reviewed laboratory, animal, or human studies of pentadeca arginate. No clinical trial data in humans are available, and its safety, pharmacology, and efficacy are uncharacterized. Any evidence cited for related peptides such as BPC-157 should not be assumed to apply to PDA.
03 · Regulatory status
Pentadeca Arginate (PDA) is in the research phase with limited clinical data in humans. Current evidence is primarily derived from preclinical (animal or in vitro) studies.
No lawful pathway today
Pentadeca Arginate (PDA) is not FDA-approved and does not currently have a lawful prescription or compounding pathway in the United States, so we do not sell it and will not book a consultation for it. That can change: in 2026 FDA began reviewing several peptides for compounding. If you are working on the goal it is studied for, a licensed clinician can tell you what is lawfully available, which may be something else.

Looking for a lawful, clinician-prescribed option for injury recovery and tissue repair?
Pentadeca Arginate (PDA) is a research compound, is not FDA-approved, and has no lawful US compounding pathway, so we do not offer it and no clinician we work with will prescribe it. Products sold online as “research chemicals” are not made or tested to the standards required of medicines. If you are working on injury recovery and tissue repair, a licensed clinician can tell you at a free consultation whether an FDA-approved or lawfully compounded treatment fits you, or whether nothing does.
