Common questions

Everything researchers ask before ordering.

Can’t find what you’re looking for? Get in touch.

Yes. Every order ships from our United States facility — nothing is drop-shipped from overseas and nothing crosses a border after you order. Orders with payment cleared before 3 PM ship the same business day, USPS or UPS Priority, tracked, typically arriving in 2–3 business days.

Every lot is analysed by an independent third-party laboratory before it is released for sale — HPLC with UV detection for purity, LC-MS for identity confirmation. We publish the certificate as issued, against the batch number printed on your vial, rather than quoting a number at you. Look up any batch.

The batch number on the vial maps to a published Certificate of Analysis showing the compound, lot, method, test date, measured purity and the identity confirmation. It is on the public batch page before your order ships — you do not have to email us for it, and you can read it before you buy.

Everything in this catalog is sold strictly for laboratory research use. It is not a drug, not a supplement, and not for human or veterinary consumption. We publish no dosing guidance and make no claims about outcomes in people. Confirming research use at checkout is a condition of the sale.

Radical transparency

Anyone can claim purity.
We publish the paperwork.

Certificates of Analysis are published against the batch number on your vial and are searchable in the COA library — check any lot before you order, and after it arrives.

01

Every batch, not every product

Testing is per-lot. A certificate covers the exact lot your vial was filled from, not a sample from a batch made two years ago.

02

Searchable by batch number

Every vial carries a batch number you can look up here before or after you buy. You do not have to email anyone to check a lot.

03

Independent, not in-house

Analysis is performed by independent third-party laboratories — not by us, and not by the manufacturer. Every lot is certified at source before it reaches our facility, and we publish that certificate as issued.

04

HPLC-UV and LC-MS together

Purity and molecular identity are separate questions. Both are answered before a lot is released.

How we verify

Tested before it ever
reaches your bench.

Radical transparency is the entire premise. Every lot passes independent analysis and the results are published by batch number — not hidden behind a “trust us.”

VIEW COA LIBRARY
01

Independent HPLC purity analysis

Third-party laboratories confirm purity on every lot before it is released for sale.

02

Mass spectrometry identity

LC-MS confirms the compound matches its label at the molecular level.

03

Endotoxin screening

LAL testing on applicable lots, documented alongside purity and identity.

04

Published, searchable COAs

Every batch number maps to a downloadable certificate — publicly, not on request.

How it works

From lab to bench
in three steps

01

Check the paperwork first

Every price and every certificate is public. Look up a batch and read its lab report before you spend anything — no account, no email, no form.

02

Open a research account

Ordering takes a research account — your entity, your protocol, and a 21+ research-use-only attestation. Two minutes, once.

03

Packed cold, shipped from the US

Paid before 3PM CT and it leaves the same business day — insulated, cold-chain handled, tracked to your door.

About Synthrex

You shouldn’t have to trust me.
You should be able to check.

Most suppliers in this market ask you to take their word for it — a purity number on a product page, no lot, no laboratory named, no way to check it. Synthrex is one person. I dropped out of school to build it because I got tired of buying research material I could not verify.

Every lot we carry is analysed by an independent laboratory before it reaches us, and we publish that certificate as issued, against the batch number printed on your vial — whether it flatters us or not.
