Pentadeca Arginate (PDA): research, prices and suppliers
A pentadecapeptide sharing the amino-acid sequence of BPC-157, offered as an arginine salt for improved solubility and stability.
Pentadeca Arginate, often abbreviated PDA, carries the same 15-amino-acid sequence as the well-known peptide BPC-157. The difference lies in the counter-ion: instead of an acetate salt, the sequence is bound to arginine, which suppliers describe as improving solubility and shelf stability. Independent studies examining this specific salt form are not yet available.
Facts
- Amino acids: 15
Evidence
- Because Pentadeca Arginate shares its sequence with BPC-157, the available evidence draws on studies of the parent sequence. A 2025 systematic review evaluated 35 preclinical animal studies on muscle, tendon, ligament, and bone injuries, which mostly described positive healing outcomes. Vasireddi et al. 2025, HSS Journal, PMID 40756949
- A cell study described activation and upregulation of VEGFR2, a key receptor in blood vessel formation, for the same sequence, accompanied by increased endothelial tube formation in the laboratory model. Hsieh et al. 2016, Journal of Molecular Medicine, PMID 27847966
Frequently asked questions
Is Pentadeca Arginate the same as BPC-157?
The amino-acid sequence is identical. The difference lies in the counter-ion: BPC-157 is usually offered as an acetate salt, Pentadeca Arginate as an arginine salt, which suppliers describe as improving solubility.
Are there independent studies on the arginine salt form?
No, a targeted literature search found no independent studies on the arginine salt form itself. The available evidence relates to the BPC-157 parent sequence.
Is Pentadeca Arginate an approved medication?
No. It is not approved in the EU or the United States and is sold exclusively as a research chemical for laboratory use.

Questions about interpretation
What does the search “Pentadeca Arginate (PDA) protocol” mean?
“Protocol” is often used to mean a regimen. This page explains research and documented listings. It contains no doses, cycles or instructions for human use. An online regimen is not scientifically validated simply because it is widely shared.
Sources and data basis
These references come from the existing dataset. A link alone verifies neither a study claim nor supplier quality. Uncertainty remains explicit where records are undated or incomplete.
