The short version

Pepticore synthesises, lyophilises, and packages every peptide it sells at our own facility in California — we do not outsource finished-product manufacturing to a third-party contractor. Raw peptide precursors and reagents used in that synthesis are sourced from qualified suppliers, some domestic and some international, each checked against our intake criteria before use. Every finished production lot then passes through internal quality review and independent third-party laboratory testing before it is sealed, labelled with a unique lot number, and released for sale.

This page describes our sourcing and manufacturing process. For the specifics of how each lot is laboratory-tested, see our Lab Testing & Quality Assurance Policy; to view a lot’s published results, see our certificate vault. This page supplements, and does not replace, our Research Use Only Disclaimer.

Vertically integrated by design

Our manufacturing model, in plain terms

A meaningful share of the research-chemical market works by relabelling material that arrives already finished from an overseas contract manufacturer, with little visibility into how it was made. Pepticore takes a different approach: the peptides we sell are synthesised, purified, and lyophilised in-house, at our own facility in California, rather than purchased finished from a third party and repackaged.

That does not mean every input to our process originates in the United States — the raw materials that go into synthesis are sourced from a mix of domestic and international suppliers, described below. What it does mean is that the step where a raw material actually becomes the finished peptide listed on our site happens under our own roof, under our own documented procedures, and is independently verified before it ships.

Where our inputs come from

General sourcing statement

Domestic and international suppliers

The amino acids, resins, and reagents used as inputs to our synthesis process are sourced from a mix of domestic and international suppliers of laboratory and fine chemicals. We do not publish the identities of individual suppliers on this page, for the same reason most manufacturers don’t: supplier relationships shift over time, and naming one specific vendor as “the” source would go stale the moment it changed. What stays constant is the standard every supplier is held to.

Supplier qualification

A supplier is not added to our approved list, and material from that supplier is not used in production, until it has been evaluated against our internal specification and documentation requirements. Material that arrives without the documentation we require, or that fails our intake inspection described in the next section, is rejected before it ever reaches synthesis.

Origin of the finished product

Where and how our peptides are manufactured

Our facility

Pepticore is operated by Renaissance Wave LLC, registered at 2108 N St Ste N, Sacramento, CA 95816. Peptide synthesis, purification, and lyophilisation take place at our own facility in California — we do not contract that work out to a third-party or overseas manufacturer. Finished lots are sealed and labelled in-house, then sent to our warehouse at 10727 Commerce Way Ste C, Fontana, CA 92337, for storage and order fulfilment once they clear testing.

A precise statement, not a vague one

Our Good Manufacturing Practice statement

“GMP” is frequently used as a loose marketing term in the research-chemical space, so we want to be precise about what we do and do not claim. Our facility is not certified, registered, or licensed to the pharmaceutical current Good Manufacturing Practice standard set out in 21 CFR Parts 210 and 211, and no product on Pepticore.co is manufactured, tested, or released to that standard. That standard exists for approved drug products administered to humans, and our products are not approved drugs.

What we do maintain is our own internally documented set of production and quality-control procedures — supplier qualification, in-process checkpoints, final release review, and independent third-party testing of every lot — modelled on general good laboratory and manufacturing discipline, but not equivalent to, and never represented as, pharmaceutical cGMP certification.

In short

  • Not cGMP-certified under 21 CFR 210–211.
  • Not registered with the FDA as a drug manufacturing establishment.
  • Yes to documented internal SOPs at every production step.
  • Yes to independent, outside verification of every finished lot before sale.

& shipment

A lot only advances to the next checkpoint once it clears the one before it. Material that fails supplier intake is never synthesised; a lot that fails in-process or final review is never sent for outside testing; and a lot that fails independent testing is never sealed, labelled, or sold. For the full detail of the checkpoints closest to release — our internal QC standards and how our independent lab testing works — see our Lab Testing & Quality Assurance Policy.

Cross-reference

Independent testing and Certificates of Analysis

Lab Testing & Quality Assurance Policy

This page covers sourcing and manufacturing. The methodology behind our testing — HPLC purity analysis, mass-spectrometry identity confirmation, our minimum purity threshold, and how a non-conforming lot is handled — is set out in full in our Lab Testing & Quality Assurance Policy.

Certificate vault

Every lot that clears testing has its result published, indexed by lot number, in our certificate vault. Match the lot number on your vial to its specific certificate before relying on the material for any research use.

What arrives at your door

Packaging and labelling standards

Tamper-evident sealing

Vials are sealed at the point of packaging using a tamper-evident closure, so that a vial which has been opened or interfered with after it leaves our facility is visibly identifiable as such upon receipt. If a vial you receive shows signs the seal has already been broken or tampered with, do not use the contents — contact us immediately using the details below.

Lot numbering on every vial

Every vial is labelled with the compound name, net content, and the unique lot number assigned to its production run at the point of synthesis. That lot number is the link between the vial in your hand and its specific Certificate of Analysis — see our Lab Testing & Quality Assurance Policy for how batch and lot tracking works end to end.

Labelling accuracy

Our internal release review checks that a lot’s packaging and label match its production and testing record before it ships, so the compound name and lot number printed on the vial match what was actually synthesised and tested — not a generic template applied across a product line.

To avoid any misunderstanding

What this disclosure does not claim

In-house manufacturing and independent testing are meaningful quality signals, but they are not the same thing as the assurances below. Nothing on this page should be read to claim any of the following:

  • That our facility holds pharmaceutical cGMP certification under 21 CFR 210–211.
  • That our facility is registered with the FDA as a drug manufacturing establishment.
  • That any raw material input is domestically sourced — inputs may be domestic or international.
  • That tamper-evident packaging guarantees sterility or safety for administration to a human or animal.
  • That our products are approved, cleared, or evaluated by the FDA for any use.
  • That in-house manufacture substitutes for the independent laboratory testing described separately.

Where we use “Made in the USA” or similar language anywhere on our site, we mean specifically that final synthesis, purification, and packaging occur at our California facility — consistent with the FTC’s Made in USA labelling standard, we qualify that claim rather than representing that every raw material input is of U.S. origin.

U.S. federal framework

The federal standards behind our sourcing and manufacturing claims

FTC Made in USA Labelling Rule (16 CFR Part 323)

An unqualified “Made in USA” claim requires that a product be “all or virtually all” made in the United States. Because our raw material inputs can include internationally sourced components, we describe our origin claim precisely — synthesis, purification, and packaging performed at our California facility — rather than making a blanket “Made in USA” claim that our supply chain doesn’t fully support.

FTC Act, Section 5 — substantiated claims

Any factual claim we make about sourcing, manufacturing location, or quality controls must be truthful and substantiated at the time it’s made. We hold our own marketing to that standard, including the claims made throughout this page.

FD&C Act intended-use doctrine (21 U.S.C. § 321(g))

Consistent with our Research Use Only Disclaimer, nothing on this page describing our sourcing or manufacturing process is intended to state or imply a use of our products in the diagnosis, treatment, cure, mitigation, or prevention of disease in a human or animal.

Not an FDA evaluation

Nothing in this disclosure, including our description of our manufacturing process and quality checkpoints, constitutes or implies FDA evaluation, clearance, or approval of any product for any use in humans or animals.

State-level compliance

State and regional rules affecting our sourcing claims

Beyond federal rules, state-level advertising and consumer-protection law governs how we may describe where and how our products are made. We hold our sourcing and manufacturing claims to the strictest applicable state standard.

California

Home state standards

As a California-registered, California-manufacturing business, our sourcing and origin claims are subject to California’s Business & Professions Code §§ 17200 and 17500 governing unfair competition and false advertising, and to California’s own “Made in USA” standard under Business & Professions Code § 17533.7, which is stricter than the federal rule in certain respects. Where applicable, we provide Proposition 65 warnings under the Safe Drinking Water and Toxic Enforcement Act.

All 50 states

Unfair or deceptive practices statutes

Every state maintains its own Unfair or Deceptive Acts and Practices (UDAP) law governing the accuracy of origin, sourcing, and manufacturing claims made in advertising. Any specific claim we publish about where a product is made must hold up under whichever state’s standard applies to the buyer.

Evolving legislation

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.

Our commitment on emerging state law: because state-level regulation of research chemicals, peptides, and supply-chain disclosure requirements continues to change, we do not treat the summary above as complete or static. We monitor state legislative activity on an ongoing basis and update our practices and disclosures as needed. Buyers remain independently responsible for confirming that purchase, possession, and use of a given compound is lawful in their own state before ordering.

Consumer protection

Your rights regarding sourcing and manufacturing

Accurate origin claims

You are entitled to sourcing and manufacturing claims that are truthful and substantiated. If you believe any statement on this page is inaccurate, contact us using the details below and we will investigate and correct it.

Tamper and seal issues

If a vial arrives with a broken or compromised seal, or a lot number that does not appear in our certificate vault, this is handled under our Return & Refund Policy — contact us before using the material.

Statutory rights preserved

Nothing in this disclosure limits any statutory consumer right or remedy available to you under applicable federal or state law.

Revisions

Changes to this disclosure

Because our supplier relationships, production processes, and applicable law can all change over time, we review this disclosure regularly and update it whenever our sourcing or manufacturing 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 disclosure.
