How ChemLabs works.

ChemLabs makes and sells research peptides. Everything in the catalogue is ours: we control the synthesis, run quality control, hold the inventory, release the batch, and ship the order. There is no reseller in the chain, and no batch we cannot trace back to the run that produced it.

The only outside parties involved are the independent laboratories that assay our batches. They test; they do not sell. Their reports are published against the listing whether or not the numbers flatter us.

Everything we sell is supplied strictly for in-vitro laboratory research use. These are not medicines and are not for human or veterinary administration. Section 06 sets out what that means in practice.

Compounds are produced to a written release specification that defines the acceptance range for identity, purity, and mass for that product. The specification is fixed before a run starts, so a batch is measured against a standard set in advance rather than one written to fit the result.

Controls on every run

• Lot identity. Every run gets a batch number that follows the material from synthesis through to the vial you receive.
• Storage. Lyophilised material is held under temperature control, and cold-chain products are logged from release through to dispatch.
• Segregation. A batch that has not cleared assay cannot be picked for an order. Release is a state change, not a judgement call at the packing bench.

Around 6% of runs never reach the catalogue. They are held for retest, reworked, or discarded.

Our own quality control is not the last word on a batch. Before release, a sample from every batch goes to an independent laboratory for assay. We publish the certificate of analysis it returns against the listing, and the batch number on your vial matches it.

When the report comes back, the reported figures — HPLC purity, mass spectrometry result, peak profile, and the identity of the issuing laboratory — are reconciled line by line against the release specification for that product.

What holds a batch

• Purity below the release specification for the product class.
• A mass result inconsistent with the peptide sequence being produced.
• A report that duplicates one already on file — the signature of a document error or an altered result.
• A report from a laboratory we cannot identify, or whose issuing details do not check out.

A held batch does not ship. It goes to an analyst, who either clears it, orders a fresh assay, or writes the run off. The checks decide what gets looked at; a person decides what happens to it.

What an assay does not prove

A certificate describes the sample the laboratory received. On its own it cannot prove that the sample represents the whole batch. That gap is why batch numbers are bound to orders, why we run random second assays pulled from live inventory, and why buyer protection exists regardless of what any report says.

1. Placed. Checkout authorises and holds your payment. Vials are reserved from a named batch. We hold the order; we do not yet hold the money.
2. Confirmed. Within 24 hours we confirm stock and the exact batch you will receive, and attach its certificate of analysis to your order. If we cannot fulfil it, the order cancels and the hold is released.
3. Shipped. Carrier tracking is recorded against the order. Temperature-sensitive products ship with cold-chain packing and are logged from dispatch onward.
4. Delivered. Payment releases to us when you confirm delivery, or automatically five days after tracking shows delivered. Reporting a problem before then keeps the hold in place.

Every order ends in one of three states: released, refunded, or under review. None of them is silence.

Report a problem from the order and your payment stays held while we look at it. We review the carrier tracking, the batch certificate, and any independent test result you supply, and resolve within 72 hours.

You are refunded in full when

• The order never arrives, or tracking shows it was never shipped.
• The material fails the specification it was sold against, evidenced by an independent assay.
• The batch number on the vial does not match the order or the published certificate.
• What arrives is not what was ordered — wrong compound, wrong mass, wrong quantity.
• The shipment arrives with its cold chain broken.

Because we are the producer, there is nobody for us to pass that cost to. A refund is written off against the batch, and a batch that generates upheld complaints is pulled from sale and retested.

Reviews follow the same rule: only an account with a delivered order for a product can review it, and we do not edit or remove reviews for being unflattering.

Everything ChemLabs sells is supplied strictly for in-vitro laboratory research. These products are not medicines. They are not approved for human or veterinary use, they must not be administered to people or animals, and nothing on this site — including purity figures, certificates of analysis, and product descriptions — constitutes medical advice or any suggestion that a product is safe or effective for use in a person.

Product descriptions state the research context a compound is studied in. They are not claims of effect, and they are not an invitation to self-experiment. We publish no dosing guidance, no protocols, and no administration instructions, and we will not provide them if asked.

We decline orders that indicate intended human use, personal use, or recreational use. Reselling material bought here as fit for human consumption is a misuse of it and a breach of our terms.

By ordering you confirm you are acquiring these materials for legitimate research purposes, and that you are responsible for compliance with the laws and institutional requirements that apply to you — including any import restrictions in your country. Some compounds we list are controlled or restricted in some jurisdictions; checking that before you order is your responsibility.

Order problems, refunds, batch and certificate queries, and security disclosures all route through one inbox: support@chemlabs.shop.

Include your order reference — it is on the order row under My orders and on your receipt. For a quality query, attach any independent test result you have; it materially speeds up the review.

We do not answer questions about dosing, administration, or use in humans or animals, and asking will not change that answer.
