Oxytocin

• Every new batch gets a report from an outside lab. We use Vanguard Laboratory (Washington), Eagle Analytical (Texas) and Ethos Analytics (Arizona). Every result we publish is that lab's, not ours.
• Some Vanguard reports are also on the lab’s own website. Those show a “Verify online” link.
• Vanguard is behind on uploading, so a newer batch may not be online yet.
• Vanguard will check any of our reports for you: call (360) 967-7010 or email [email protected].
• To match a report to your vial or bottle: the batch number on the label should be the same as on the certificate.

5 mg · In testing
A 5 mg batch is in testing. It becomes orderable here, with its certificate, once it has passed every test and is on the shelf.

• February 2025: we started putting a lab report on every batch. One outside lab, seven rows: is it the right compound, is it clean, how much is inside, does that match the label, any germ dust, one germ test, and the lab’s sign-off.
• April 2025: heavy metals added. Eight rows.
• October 2025: germs checked two ways, at two labs. Vanguard grows a sample for 14 days; Eagle Analytical counts living cells the same day. A batch has to pass both. Nine rows.
• February 2026: the full panel. Four tests added: leftover cutting acid, leftover cleaning liquid, is the vial sealed tight, does it dissolve. Three vials measured for how much is inside, instead of one. Fourteen rows. Every new batch since June 2026.
• August 2026: the adulterant screen: anything in the vial that should not be there. Fifteen rows on every new batch, on 23 units. Every new lab has to pass our onboarding checks first; Ethos Analytics joined in September.
• Which standard is my batch? Every certificate on this site shows how many tests that batch had: 15 for batches tested since August 2026, 7 to 14 for earlier ones. The certificate head says the number; the rows show which.

• Since August 2026, every new lab has to pass the checks below before we rely on any of its reports.
• No ties to product sellers. We will not use a lab that is owned, in whole or in part, by a company that sells peptides.
• We look for labs whose main clients are laboratories and industrial businesses, not consumers.
• We require ISO/IEC 17025 accreditation: an outside body has checked the lab against the international standard for testing labs.
• That outside body must be a recognized one, such as A2LA, ANAB or PJLA.
• The test methods we use on peptides must be listed on the lab’s scope of accreditation: the public list of tests that lab is approved to run.
• Accreditation only for food or cannabis testing does not count.
• We ask labs to use USP test methods wherever one exists. USP (the United States Pharmacopeia) publishes standard test methods, so a test is run the same way in every lab and results can be compared.
• We require labs to run their testing under GMP or GLP: written procedures, calibrated instruments and a record of every test, so any result can be traced and checked later.

• The size is how much we order, for example 30 mg.
• The lab measures the peptide in the vial by HPLC against a reference standard (no scale involved). It can be a little over or under, for example 34.08 mg.
• We always show you the real number, never rounded.

• Vials ship at room temperature. No ice pack is needed.
• Each vial is bubble-wrapped inside a padded mailer.
• When it arrives, store it the way the label says.

• “Label created” means the carrier has not scanned the box yet.
• It usually updates after the first scan.
• If it does not move, read the full article or ask us in chat.

• Not every vial has a strong vacuum. Some are sealed under low pressure, some with nitrogen gas.
• A weak or missing vacuum is not a defect by itself.
• The seal is tested on every new batch (container closure). On an earlier batch the certificate shows whether that test ran.
• If the seal is torn or lifted, see the return policy.
