Lab Testing & Quality Assurance Policy
This page sets out, in specific and verifiable detail, how every peptide lot listed on Pepticore.co moves through internal quality control and independent laboratory testing before it is released for sale — and, just as importantly, exactly what our testing does and does not confirm.
The short version
Every peptide lot we sell moves through documented internal checks during production, and is then sent to an independent third-party laboratory for HPLC purity analysis and mass-spectrometry identity confirmation before it is ever listed for sale. Results are published per lot, in our certificate vault, and tied to the exact lot number on the vial the buyer receives.
A Certificate of Analysis confirms chemical identity and purity. It does not confirm sterility, safety, or suitability for use in or on a human or animal, and it is not a substitute for a qualified researcher’s own evaluation of a compound before use in their protocol. This policy supplements, and does not replace, our Research Use Only Disclaimer.
Why we test every lot instead of relying on paperwork alone
A lot of research-chemical suppliers pass along whatever documentation arrived with their raw material and call it a Certificate of Analysis. We built Pepticore around a different rule: nothing is listed for sale until a production lot has been independently tested by a laboratory that has no involvement in, or financial interest in, our production process.
That distinction matters for two reasons. First, it gives us an outside check on our own manufacturing — a way to catch a synthesis or packaging error before it ever reaches a customer, rather than after. Second, it gives the researchers who buy from us something they can actually evaluate: a documented, lot-specific result they can weigh against their own protocol requirements, rather than a marketing claim they have to take on faith.
Nothing in this policy is a representation that our products are safe, effective, or appropriate for administration to a human or animal. It describes how we verify what a lot is — its chemical identity and its purity — not what it is safe to do with it.
Internal quality control standards
Raw material intake review
Incoming peptide precursor material and reagents are checked against our internal specification sheets before synthesis begins. Material that does not meet our intake criteria is rejected and is not carried forward into production — a batch does not get a second chance to pass at a later checkpoint.
In-process controls
Synthesis, cleavage, and purification follow written internal procedures, with in-process sampling at defined checkpoints so a deviation is caught while it can still be corrected, rather than discovered only at final testing.
Final internal release review
Before any lot is packaged and sent out for third-party testing, we review its documentation for completeness and confirm the packaging and label match the compound and lot record on file. A lot with an incomplete or mismatched record does not move forward.
What our internal standard is not
We do not represent our facility as certified to a pharmaceutical current Good Manufacturing Practice standard under 21 CFR Parts 210–211, and no product on Pepticore.co is manufactured or released to that standard — our products are not approved drugs, and that certification does not apply to them. Our internal controls are our own documented research-chemical production standards, independently checked by outside testing, not a pharmaceutical manufacturing certification.
Testing methodology: HPLC and mass spectrometry
High-performance liquid chromatography (HPLC)
HPLC separates a sample into its individual components as it passes through a column, then measures the amount of each. This tells us how much of the sample is actually the target peptide versus related synthesis byproducts, degradation products, or residual reagents. Purity is expressed as a percentage of total peak area attributable to the target compound, and every lot is measured against our internal minimum threshold before it can be released.
Mass spectrometry
Mass spectrometry measures the mass-to-charge ratio of the sample to confirm its molecular weight matches what is expected for the specific peptide listed. This step exists precisely because HPLC purity alone cannot catch every problem — a sample could measure as highly “pure” and still be the wrong compound entirely. Identity confirmation is how we rule that out.
Minimum purity threshold
A lot that does not meet this threshold, or whose confirmed identity does not match its listing, is not released for sale under any label.
Our independent laboratory standard
Testing is performed by an independent, U.S.-based third-party laboratory with no ownership relationship to Pepticore or Renaissance Wave LLC, and no financial stake in whether a given lot passes. The laboratory receives a labelled sample and tests it against our stated identity and purity requirements using HPLC and mass spectrometry instrumentation — it does not receive, and its result is not influenced by, any information about our internal production process.
Because we run production across separate periods and test each lot independently, the specific laboratory assigned to a given lot — along with the instrumentation and reference methods it used — is disclosed directly on that lot’s published Certificate of Analysis in our certificate vault, rather than fixed to a single name on this page. That is a deliberate choice: it means every claim about who tested a specific vial is tied to a document you can check against that vial, not a general statement about our supply chain.
What we commit to, regardless of which lab we use
- Testing on a submitted, labelled sample — not a supplier-provided or self-reported result.
- Purity by HPLC and identity by mass spectrometry on every production lot, not a sample of a product line.
- Results reported directly to us and published unedited — we do not selectively publish, average, or omit an unfavorable result.
- A lot that fails either test is not sold under any label, regardless of the reason for the failure.
How our batch and lot tracking system works
Every production run is assigned a unique lot number at the point of synthesis. That lot number is printed on the vial label the buyer receives, and it is the key that ties together everything we and our testing partner know about that specific run:
logged to lot record
in-process checks
result recorded
lot label applied
Because testing is performed per lot rather than once per product line, two vials of the same peptide purchased months apart may carry different lot numbers, each independently tested and each with its own Certificate of Analysis. When you receive a vial, always match the lot number printed on it to the certificate in our certificate vault that shares that exact number — not simply the product name — before treating it as verified.
Manufacturing and storage standard disclosures
Facility
Pepticore is operated by Renaissance Wave LLC, registered at 2108 N St Ste N, Sacramento, CA 95816. Our peptides are synthesised and lyophilised at our own California-based facility — we do not outsource synthesis to third-party contract manufacturers. Once a lot clears internal review and independent testing, finished vials are packaged and shipped to our warehouse at 10727 Commerce Way Ste C, Fontana, CA 92337, for storage and order fulfilment.
Storage before shipment
Lyophilised (freeze-dried) peptide material is sealed and stored at our warehouse in accordance with the handling conditions indicated on the product label until an order ships. After you receive a vial, general laboratory practice for lyophilised peptide material is to store it as directed on the label — typically refrigerated or frozen, protected from light and moisture — and to avoid repeated freeze-thaw cycles of any reconstituted material. This is general research-handling guidance, not instructions for administration or use in or on a living organism.
What our facility is not
Our facility is not registered with the FDA as a drug manufacturing establishment, and no product we sell is manufactured, stored, or shipped to a pharmaceutical stability or storage standard. All handling should take place within a properly equipped laboratory research setting only.
What our Certificates of Analysis confirm — and what they do not
A Certificate of Analysis from our testing partner confirms two specific things about the lot tested: its chemical identity, by mass spectrometry, and its purity, by HPLC, at the time of testing. It does not confirm, certify, or imply any of the following, regardless of how the compound is described elsewhere on our site:
- Sterility, or freedom from microbial contamination.
- Absence of endotoxins, heavy metals, or other trace contaminants not covered by the stated methods.
- Safety, efficacy, or suitability for administration to a human or animal, in any dose or form.
- Stability of the compound over time, or after storage conditions outside our control.
- Compliance with any pharmaceutical, clinical, or veterinary manufacturing standard.
- Fitness for any specific research protocol — that determination remains the buyer’s own responsibility.
If a use of our products depends on any of the assurances above, our Certificates of Analysis do not provide it, and no statement on this page should be read as supplying it by implication.
Accessing your Certificate of Analysis
Certificate vault
Every lot-specific Certificate of Analysis we publish is available, free of charge, in our certificate vault, indexed by lot number. There is no login or purchase requirement to view a published certificate.
If you can’t find your lot
Match the lot number on your vial to the corresponding certificate before relying on the material for any research use. If you cannot locate the certificate for the lot you received, contact us at contact@pepticore.co or +1 (571) 688-3488 and we will provide it directly or investigate.
How non-conforming batches are handled
If internal review or independent laboratory testing shows that a production lot does not meet our release criteria — on identity, on purity, or on documentation — that lot is not sold. It is not listed with a Certificate of Analysis, and it is either reworked internally or destroyed. A non-conforming lot never reaches a customer under a Pepticore label.
If you have a documented reason to believe a specific vial you received does not match its published Certificate of Analysis — for example, an independent test result you can share with us — contact contact@pepticore.co or +1 (571) 688-3488. We will investigate, and where our findings or a legitimate outside laboratory result confirm a genuine non-conformance, we resolve it under the terms of our Return & Refund Policy.
The federal standards behind our quality claims
FTC Act, Section 5 — substantiated advertising
The Federal Trade Commission requires that objective claims in commerce be truthful and substantiated before they are made. Our purity and identity claims are backed, lot by lot, by the actual independent laboratory data published in our certificate vault — not by an unsupported blanket statement about the product line as a whole.
FD&C Act intended-use doctrine (21 U.S.C. § 321(g))
Under federal law, a chemical’s legal status turns heavily on how it is marketed. We describe our testing results strictly as laboratory data about a research compound — never as a statement about what the compound will do for a person — for this reason, consistent with our Research Use Only Disclaimer.
Uniform Commercial Code — description of goods
Under the Uniform Commercial Code as adopted in the states where we do business, a specific factual claim we make about a lot — such as a stated purity result — functions as part of the description of the goods sold. We do not disclaim the accuracy of our own published testing data, and nothing in this policy limits any warranty or remedy a buyer is entitled to under applicable state law.
Not an FDA evaluation
Nothing in this policy, including our purity and identity testing, constitutes or implies FDA evaluation, clearance, or approval of any product for any use in humans or animals. Our testing verifies laboratory chemical data only.
State and regional rules affecting our quality claims
Beyond federal law, every state maintains its own rules on how a business may describe the quality and testing of what it sells. We hold our published testing claims to the strictest applicable state standard, and track state-level developments in peptide-specific regulation as they emerge.
Home state standards
As a California-registered, California-manufacturing business, our purity and identity claims are subject to California’s Business & Professions Code §§ 17200 and 17500 governing unfair competition and false advertising, in addition to federal law. Where applicable, we provide Proposition 65 warnings under the Safe Drinking Water and Toxic Enforcement Act for chemicals known to the state to cause cancer or reproductive harm.
Unfair or deceptive practices statutes
Every state maintains its own Unfair or Deceptive Acts and Practices (UDAP) law governing the accuracy of quality, testing, and purity claims made in advertising. Any specific numeric or testing claim we publish — including our stated purity threshold — must hold up under whichever state’s standard applies to the buyer.
Peptide-specific state rules
Several states, including Louisiana under La. R.S. 37:23.5, have begun legislating specifically around peptide dispensing by licensed healthcare providers and compounding pharmacies. That framework governs clinical dispensing to patients and does not apply to Pepticore, since we are not a healthcare provider, prescriber, or compounding pharmacy and do not dispense any product for administration to a patient.
Our commitment on emerging state law: because state-level regulation of research chemicals and peptides continues to change, we do not treat the summary above as a complete or static list. We monitor state legislative activity on an ongoing basis and reserve the right to update our testing claims, restrict shipment to a given state, or decline an order where we reasonably believe a sale would violate that state’s law. Buyers remain independently responsible for confirming that purchase, possession, and use of a given compound is lawful in their own state before ordering.
Your rights regarding testing and quality
Lot-specific documentation
You are entitled to the exact Certificate of Analysis matching the lot number on the vial you receive, published in our certificate vault — never a generic or substituted report for a different lot.
Independent verification
You are free to send any material you purchase to your own independent laboratory for confirmatory testing at your own expense. We welcome that verification and will work with you in good faith on any discrepancy you identify and can document.
Non-conformance remedies
Where a genuine testing or quality non-conformance is confirmed, our Return & Refund Policy sets out how the issue is resolved. Nothing in this policy limits any statutory consumer right or remedy available to you under applicable federal or state law.
Changes to this policy
Because testing standards, our production process, and applicable law can all change, we review this policy regularly and update it whenever our practices or the relevant legal framework change. The “last updated” date at the top of this page always reflects the current version. Continued use of Pepticore.co after an update constitutes acceptance of the revised policy. We encourage researchers to review this page periodically, particularly before placing a repeat order.
