BPC 157

Pentadeca Arginate (PDA) is a next-generation synthetic peptide derived from a naturally occurring protein in human gastric juice — structurally related to BPC-157, with an arginate modification that enhances stability and may improve bioavailability.

Overview

PDA is a 15-amino-acid peptide used in regenerative medicine as an adjunct to support tissue repair, modulate inflammation, and promote vascular health. Preclinical research demonstrates activity across multiple biological repair pathways — including angiogenesis, collagen synthesis, and growth factor modulation.

What Makes PDA Different

Arginate Modification

Replaces the traditional acetate salt with an arginate group — enhancing chemical stability, particularly in acidic environments, for improved bioavailability

Dual Nitric Oxide Pathway

Arginine is the substrate for nitric oxide synthase — so PDA's arginate group amplifies NO-mediated vasodilation beyond what the VEGFR2 pathway alone produces

Lyophilized Injectable

Supplied as a freeze-dried powder for reconstitution before subcutaneous injection — preserving peptide potency and stability through dispensing

FAQs

Administration

PDA is supplied as a lyophilized powder that must be reconstituted before use and administered subcutaneously. Dose, frequency, and treatment duration are determined entirely by your prescribing provider based on your individual health profile and goals.

Precautions

PDA is not FDA-approved — all use is off-label and investigational. Written informed consent is required before treatment. Not recommended in patients with active or prior malignancy (due to angiogenic activity), pregnancy, breastfeeding, or pediatric use. Patients with autoimmune conditions should consult their provider before starting. Disclose all medications and health conditions prior to treatment.

Storage

Store unreconstituted vials refrigerated at 36°F–46°F (2°C–8°C), protected from light. Do not freeze. Once reconstituted, refrigerate and use within 28 days. Discard if the solution appears cloudy or discolored. Dispose of used needles in an approved sharps container.
