Before you order.

Everything on this site is sold as a laboratory reagent. These are not drugs, supplements, foods, or cosmetics. They have not been evaluated by the FDA, and they are not intended for human or veterinary use of any kind. Orders are accepted from qualified researchers and institutions only.

No. We do not provide dosing, administration, protocol or usage guidance of any kind, and our support team is not permitted to answer those questions. We can only discuss what a compound is, what the certificate says about it, and how to store and handle the vial.

Qualified researchers, laboratories, universities and institutions. By placing an order you confirm you are 21 or older, that you are purchasing for legitimate laboratory research, and that you accept responsibility for lawful handling, storage and disposal.

Research chemicals are legal to purchase for laboratory use in most of the United States, but rules vary by state and by country, and some destinations restrict import entirely. You are responsible for knowing and following the law where you are. If you are unsure, check before you order.

It is your acknowledgement that you are a qualified researcher and that the materials are for laboratory research only. We record it with the order. Without it, the order cannot be placed.

No. We sell laboratory reagents to researchers. We do not market these products for personal use and we will cancel and refund any order where the intent is clearly outside laboratory research.

The lot number is printed on the label of the vial you receive. Find that lot on the product page or search it in the certificate library and you get the report for that exact batch — not a representative sample, not last quarter's.

Purity as a percentage of total peak area by reverse-phase HPLC with UV detection, plus mass confirmation by electrospray mass spectrometry, the appearance of the material, the lot number, the date tested and the laboratory that ran it.

An accredited third-party laboratory. Never our own bench, and never the facility that synthesised the material. That separation is the entire point of publishing the number.

Do not open the vial. Email support with your order number and a photo of the label and we will identify the batch and sort it out. A mismatch is always worth reporting.

Because that lot has been tested but the report has not been published to the site yet, or the current batch is still with the lab. We would rather show you an honest gap than a certificate belonging to a different batch. They go up as they clear.

A separate test measuring bacterial endotoxin by LAL against USP <85>. Where we have one for a lot, it is attached alongside the purity certificate on the product page.

Our catalog target is above 99%. The actual figure for the batch you receive is on its certificate — read that number rather than the marketing one.

The published certificate includes it where the lab provides it. If you need something further for your records, email support with the lot number and we will ask the lab.

Every batch. A sample is pulled from each finished lot before any of it is listed for sale. If a lot does not clear, it does not ship.

The methods shown at checkout are the ones currently available to your order. If none appear, contact support and we will sort out an alternative.

It appears as NOLIMITLABS, not as the product name. If you see that charge and do not recognise it, email support and we will identify the order for you.

Yes, any time before it ships. Email support with your order number as soon as you can. Once the label scans at the carrier we cannot pull it back.

Yes. Email support with the compounds, quantities and your institution and we will quote you. Bulk lots are tested the same way as retail lots.

No, you can check out as a guest. An account makes it easier to track shipments and find past lot numbers later, which is worth having if you order regularly.

Enter it in the promo code field on the cart page and press Apply. The discount shows in the totals before you reach payment. One code per order.

Where required. Any tax is calculated at checkout from your shipping destination and shown before you pay.

Your order confirmation email is a valid receipt. If you need a formal invoice with a purchase order number or institutional billing details, email support and we will issue one.

Rates are calculated at checkout by destination. US orders over $150.00 ship free, and everything travels in one cold pack, so adding more vials does not add shipping cost.

Orders placed before 2PM CT on a business day go out the same day. Anything after that, or on a weekend, ships the next business morning.

US delivery typically lands in two to four business days once dispatched. Tracking is emailed the moment the label scans at the carrier.

Gel packs and insulation around the vial, sealed against transit heat, in a plain outer box with no indication of the contents.

Yes. Customs handling, duties and any import fees are the buyer's responsibility, and some destinations restrict these materials. Check your local rules before ordering — we cannot refund a parcel seized at customs.

Yes. Plain outer box, no branding on the outside, no description of the contents on the label beyond what the carrier requires.

Give it one business day — scans often lag the physical parcel, especially over weekends. If it has been longer than that with no movement, email support and we will chase the carrier.

Only before it ships. Email support immediately with your order number and the corrected address.

PO boxes are usually fine domestically. Freight forwarders are at your own risk — once a parcel is signed for at the forwarder, we cannot cover what happens after that.

Sealed lyophilized vials are stable at room temperature in transit. Store at 2–8°C short term or −20°C long term, sealed and out of light.

Usually not. Sealed lyophilized material is stable at room temperature for the length of a normal transit — the cold pack is a margin of safety, not a requirement. If the cake looks melted, collapsed or discoloured, photograph it and contact support.

A white or off-white lyophilized cake or powder, intact at the bottom of the vial. The appearance recorded for your lot is listed on its certificate.

A cake that has cracked or come loose during shipping is cosmetic and does not indicate a problem with the material. A cake that has visibly melted into a residue is worth reporting.

Stored sealed, cold and out of light, lyophilized material is generally stable for a long period. Once reconstituted, stability drops sharply — refrigerate and treat it as short-lived.

Check the catalog — where we stock supplies they are listed alongside the compounds. If you do not see what you need, email support.

Photograph the box and the vial before you unpack anything further, then email support within 72 hours of delivery with your order number. Broken seals, cracked glass or a melted cake get replaced on the next outbound run — no return shipment needed.

Email support with your order number and a photo of the label you received. We will send the correct item and cover the cost of putting it right.

Report a missing order within 30 days of shipping. We will open a trace with the carrier, and if it cannot be located we replace or refund it.

Unopened, unused vials with intact seals can be discussed within 14 days of delivery — email support first, do not ship anything back unannounced. Opened vials cannot be returned, because we cannot verify the chain of custody once a seal is broken.

Back to your original payment method, not store credit. Once issued, it typically takes a few business days to appear depending on your bank.

It will appear as NOLIMITLABS. Email support before disputing it and we will identify the order — a chargeback takes far longer to resolve than a message does.

The United States. Fulfilment, cold packing and dispatch all happen domestically.

Solid-phase synthesis at a contracted facility, followed by reverse-phase purification and desalting, then vialing and lyophilization before it goes out for independent testing.

Email support with your order number if you have one. Include photos for anything physical — a damaged vial, a label mismatch, a battered box — it gets resolved a lot faster.

Same business day in most cases. Anything raised over a weekend gets picked up the next business morning.
