I wanted to share this email

owner of Coast now Southern Aminos sent me regarding the new standards for Peptide Price. They are rebranding to Southern Aminos very soon to avoid any name crossover with a different company Costal Peptides.

I wanted to take a moment to walk you through the standards we’ve put in place at Southern Aminos (Coast Peptides)—because for us, customer safety isn’t just a checkbox, it’s the core of everything we do.

We’ve built our entire workflow around clarity and trust. Every batch is independently tested (never relying on supplier labs), and we make sure those results are easy to access. Each vial has a QR code that links directly to its specific COA—no hunting around the site. We also print the tested Mass and Purity right on the vial itself so customers can dose accurately without needing to reference anything else.

We’re now assigning batch numbers to every vial and COA, and we’ve asked our lab to include that batch number in the vial photo for full traceability. Between the QR code, printed specs, batch ID, and cap/crimp color matching, our goal is simple: give customers 100% confidence in what they’re using.

We’re also being upfront about overfills. Depending on the peptide, they can be risky, so we’re flagging any product with an overfill using a clear NOTE on the product page. And again, Mass and Purity are printed on the vial so there’s no guesswork.

Operationally, we’re scaling fast. Inventory is increasing 10x from launch, and we’ve signed with a dedicated fulfillment center that can handle hundreds of orders daily. We’re just waiting on final inventory before handing it off—should be live in a couple weeks.

Lastly, we hold ourselves to a higher standard than the lab minimum. While 98% purity is the industry baseline, we reject anything below 98.5%. Failed batches are destroyed immediately, and we notify the supplier and share the COA to help protect the broader research community.

We’re proud of what we’re building here—and we’re doing it with full transparency, zero shortcuts, and a real commitment to the people who trust us. We are not only bringing a better price than has been seen, but we hope to bring an excellent experience that everyone will love.

I just want to take a moment to also recognize the incredible work you’re doing for the research community. Your commitment to transparency, safety, and accessibility is making a real impact—not just for individual researchers, but for the integrity of the field as a whole.

By providing clear standards, reliable resources, and honest communication, you’re helping raise the bar for everyone. It’s rare to see someone so deeply invested in both the science and the people behind it. You’re not just supporting research—you’re protecting it.

Appreciate everything you’re doing to keep the community informed, safe, and moving forward.

Best,

Jeff

Founder, Southern Aminos
