Built for the people who actually read the COA.
Powerbuilt Labs supplies third-party verified research peptides to independent researchers, university labs, and life science professionals. We exist because the research peptide market is full of unverified suppliers, opaque sourcing, and missing documentation — and that's not good enough for the people doing serious work.
Why we started
Anyone who has spent time researching peptide suppliers knows the pattern: glossy product photos, vague claims about "99%+ purity," and certificates of analysis that are either nowhere to be found or look suspiciously identical across batches. We started Powerbuilt Labs because we wanted a supplier that operated the way we'd want our own lab partner to operate — fully transparent, verifiable at every step, and accountable for what's actually in the vial.
That meant building the company around a single principle: every batch ships with a real COA from an independent lab, and the customer can verify it against the batch number on the vial before they ever uncap it. Not a stock document. Not a marketing claim. A real test result for the specific lot they received.
Our testing partnership
Every compound we sell is tested by Freedom Diagnostics, an independent analytical laboratory based in the United States. They're not affiliated with us, they don't source our raw materials, and we don't see results before they're finalized. Their only job is to tell us — and you — exactly what's in each batch.
Testing methodology covers two parts: identity confirmation via mass spectrometry (LC-MS), which verifies the compound is what the label claims, and purity quantification via High-Performance Liquid Chromatography (HPLC-UV), which measures the percentage of the target compound versus impurities. The full chromatogram and mass spectrum are included on every COA, not just a single number. You can read the data yourself.
What "research-grade" means to us
The phrase gets thrown around a lot. To us it means three concrete things. First, every product meets a minimum purity threshold of 99.0% — anything below ships back to the manufacturer, never to you. Second, we maintain proper cold-chain handling from receipt through shipment; lyophilized peptides are stored at controlled temperatures in our facility and shipped same-day in insulated packaging when ambient temperatures warrant it. Third, our raw materials come from ISO-certified manufacturers with documented synthesis pathways and certificates of origin available on request.
What we don't do
We don't make health claims. We don't market to the wrong audience. We don't pretend our products are anything other than what they are: research compounds for in vitro laboratory use only, not approved by the FDA, not for human or veterinary consumption. The customers who appreciate that disclaimer are the customers we want.
Same-day shipping, real support
Orders placed before 4pm Central time, Monday through Friday, ship the same day. Tracking is automatic — you'll get an email the moment the label is generated, and another when the package shows as delivered. If you have a question, an email to [email protected] gets a real reply from a real person within 24 hours, weekdays. Not a ticketing system. Not a chatbot.
Where we ship from
Powerbuilt Performance LLC is registered and operates out of Houston, Texas. All orders ship via USPS, UPS, or FedEx from our Texas facility. We currently ship within the United States only.
