PDA 10mg (Pentadeca Arginate)

Description

Our PDA 10mg vial holds 10mg of lyophilized PDA, a 15-amino-acid peptide closely related to BPC-157. It’s intended for lab research only.

What is PDA?

PDA stands for pentadeca arginate. It’s a 15-amino-acid peptide built on the BPC-157 sequence and supplied as an arginate salt, which is meant to make it more stable in solution than standard BPC-157 acetate.

It started showing up after BPC-157 got harder to source through compounding pharmacies in the US, and it’s mostly sold as a BPC-157 alternative.

How PDA works

PDA is studied for the same reasons as BPC-157. In rodent work BPC-157 is linked to new blood vessel growth, to the nitric oxide system and to growth hormone receptor expression in tendon cells, all of which matter for tissue repair.

The arginate salt changes the counter-ion, not the working sequence. The idea is better stability in solution, though there’s no published head-to-head data comparing the two forms yet.

Published PDA studies

There are no peer-reviewed studies on PDA under that name. The reference literature is the BPC-157 work, most of it from Predrag Sikiric’s group at the University of Zagreb, which reports faster tendon, muscle and gut healing in rodents.

Treat PDA as a lightly characterized research compound, and ask us for the certificate of analysis for your batch before you rely on it.

The primary literature is on PubMed. Here’s a search for PDA studies to start from.

Reconstituting PDA 10mg

Here’s the math for 10mg of peptide:

• 1mL of diluent gives 10mg/mL
• 2mL of diluent gives 5mg/mL
• 3mL of diluent gives 3.33mg/mL

Go with whichever number is easiest to work with in your protocol, and label the vial with the concentration and the date you mixed it.

Research diluent solution or bacteriostatic water both work. Add it slowly so it runs down the side of the vial, then swirl or roll until everything dissolves. Shaking can shear peptide chains. Skip it.

How to store PDA 10mg

Unopened, keep PDA 10mg in a fridge at 2 to 8°C, or in a freezer at -20°C if it’ll be a while before you use it. Keep it out of direct light. Once mixed, keep it refrigerated and use it within about four weeks.

PDA 10mg quality and batch records

PDA 10mg is sold at 99% purity or better, measured by HPLC. That figure is the minimum for every batch we ship, not a best case.

The label on every vial shows the compound, the amount and the batch. Ask us for the certificate of analysis for your batch and we’ll email it over, which is handy if your lab keeps paperwork on file.

Keep the batch number with your records. It’s the quickest way to match a vial to its paperwork later.

Before you order PDA 10mg

Check you have everything before the vial arrives: a sterile diluent such as our research diluent solution, sterile syringes, alcohol swabs and room in the fridge. Our vial case holds ten vials upright, and the vial opener pops flip-off caps cleanly.

PDA 10mg single, 5 pack and 10 pack prices

Buying for a longer project? PDA 10mg is available in these quantities:

• Single vial: $44.00
• 5 pack: 5 vials for $198.00 instead of $220.00, about $39.60 a vial

PDA 10mg FAQ

How much is in the PDA 10mg vial?

10mg of lyophilized powder. The amount is printed on the label.

Is there a COA for PDA 10mg?

Yes. Each batch has a certificate of analysis filed under the batch number on the label. Email us that number and we’ll send it.

Is there a discount for buying more?

Yes. The 5 pack saves 10% and the 10 pack saves 15% compared with buying single vials. Pick the option from the dropdown on this page.

What do I mix PDA 10mg with?

A sterile diluent such as our research diluent solution or bacteriostatic water. The reconstitution section above shows the concentration for each volume.

How should I store it?

Sealed vials go in the fridge, or the freezer for long-term storage. Once mixed, refrigerate and use within about 28 days.
