FAQ

Ordering and payment

What payment methods do you accept?

Credit and debit cards only. We accept Visa, Mastercard, American Express and
Discover. We do not accept cryptocurrency, PayPal, Venmo, Cash App, ACH
transfers, wire transfers, money orders, checks or cash on delivery, and we
cannot make an exception on request.

How does buy 2 get 1 free work?

The offer runs sitewide on every product. Add three eligible items to your
cart and the lowest-priced of the three is discounted to zero automatically at
checkout. The discount applies in sets of three within a single order, so six
items give you two free. Items do not need to be the same compound. The offer
cannot be combined with other promotions, and it does not apply retroactively
to completed orders.

Do I need an account to order?

No. You can check out as a guest. An account stores your order history and
saves you re-entering shipping details, but nothing requires one.

Do you accept purchase orders or offer net terms?

For laboratory and institutional volumes, yes. Email {{EMAIL}} with the
compound, quantity, delivery address and your institution’s billing contact and
we will quote it. Retail orders through the site are card only.

Do you ship internationally?

Not at present. We ship within the United States only. Orders with an
international billing or shipping address will be cancelled and refunded in
full.

Will I be charged sales tax?

Sales tax is calculated at checkout where we are required to collect it. If
your institution holds a valid exemption certificate, email it to {{EMAIL}}
before ordering and we will apply the exemption to your account.

Shipping

How quickly do orders ship?

In-stock items are dispatched within one to two business days of payment
clearing. Standard delivery runs three to five business days after dispatch.
Orders placed on weekends or holidays begin processing the next business day.

Will I get tracking?

Yes. A tracking number is emailed automatically when the label is created.
It can take up to twenty-four hours for the carrier’s first scan to appear.

Can you ship to a PO box?

Yes, though a street address is faster and gives a cleaner delivery record.
We cannot ship to freight forwarders or international parcel-forwarding
addresses.

My package is late, lost or arrived damaged.

Contact {{EMAIL}} with your order number. Damage or a visibly compromised
package should be reported within five days of delivery, with photographs of the
outer packaging and the contents. Non-delivery should be reported within fifteen
days of dispatch so we can open a carrier claim inside their window.

Products and documentation

What does research use only mean?

Everything we sell is a research chemical intended for in-vitro laboratory
research. It is not a drug, dietary supplement, food or cosmetic. It has not
been approved by the FDA or any other regulator for any therapeutic purpose, and
it is not for human or veterinary consumption under any circumstances. Buying
from us means you are acquiring material for lawful research and that you are
responsible for handling and disposal under your own protocols.

How is purity verified?

Each batch is assayed by an independent third-party laboratory by
reverse-phase HPLC for identity and purity. The certificate reports the purity
percentage by peak area and the assay date. It is linked from the product page
for the batch currently shipping, and it is replaced when that batch sells
through.

Is the chromatogram on the site the real assay?

The trace shown on a product page is drawn from that batch’s own record and
is scaled to the reported purity. The authoritative document is the certificate
of analysis linked in the specification block. If the two ever disagree, the
certificate governs.

Will you advise on dosing, administration or reconstitution?

No. We supply material and its documentation. We do not provide dosing,
administration, reconstitution-for-use or protocol guidance of any kind, and we
cannot answer questions that presuppose human use. This is not us being
unhelpful. It is the line between supplying a research chemical and marketing an
unapproved drug, and we do not cross it.

How should material be stored?

Lyophilised peptides are stable in transit at ambient temperature. On
arrival, store in the refrigerator and protect from light. Each product page
carries the specific handling note for that compound. Follow your own laboratory
protocol.

How long is material good for?

Stored as above and kept sealed, lyophilised material is generally stable for
an extended period. We do not publish an expiry date because stability depends
on your storage conditions once the vial leaves us, and any figure we printed
would be a guess about your freezer rather than a fact about the compound.

Returns

Can I return an order?

Unopened items in original packaging can be returned within thirty days.
Opened vials cannot be returned, because chain of custody and sterility cannot
be verified once a seal is broken. Anything that arrives damaged, incorrect or
not conforming to its certificate is replaced or refunded in full. The full
terms are on the refund policy page.

Everything else

How do I reach a person?

Email {{EMAIL}}. We answer during {{HOURS}} and aim to reply within one
business day.
