Arsenic, cadmium, lead and mercury were screened in the historical sample and reported as not detected. That report does not measure purity and does not confirm identity.
Janoshik heavy-metals report, task #108876Triple-receptor research peptide
RTA
An investigational triple-receptor peptide, supplied freeze-dried for laboratory research only.
RTA is the store code for this research reference peptide. We supply it freeze-dried, with catalog lot details, for laboratory research only. Here is what the batch record carries.
Form Labs materials are research reference materials, not the approved medicines; no Form Labs product is approved for human or veterinary use.
Current lot pricing
Base vial price: $149.00 AUD
Supplied strictly as reference material for in-vitro laboratory research. Not a medicine, supplement, or food. Not for human or veterinary use.
Research use onlyWhy this molecule is studied
Why researchers study it.
RTA is studied in the published literature as a triple agonist - one peptide acting on three receptor systems at once. The body of work spans receptor studies, structural biology, animal models, and human trials.
It isn't an approved medicine anywhere. Everything here is about that published research and about which batch you're getting - not a claim about what this vial will do.
Form Laboratories supplies it freeze-dried, for laboratory research only, with available reports clearly separated from the listed lot.

The research
What the published studies found.
Vial sizes on this catalog record - 10, 20, and 30 mg. The available 15 mg sample report verifies none of these sizes or their listed lot.
Catalogue recordStorage range listed in the catalog; not established by the sample report.
Form Labs catalogue record30-day purity guarantee against the COA supplied with your order or available on request: an independent re-test below that purity refunds the order in full.
Form Laboratories guaranteeFigures outside lot paperwork describe third-party research records for the molecule. They are not Form Labs product results or use claims.

Plain-language research labels.
Reference material, properly documented. Here's what the batch record carries - not a description of what this vial does.
Purity
The available historical 15 mg sample report is a heavy-metals screen for lot FL20260410-RETA-15. It does not measure purity or verify the listed RTD-2506 lot.
Identity
The available heavy-metals report does not confirm compound identity. A matching current certificate for the listed lot and sizes is unavailable.
Traceability
Compare the catalog lot with the sample lot printed on the report. They differ here; this report does not establish current identity, purity or release status.

FAQ
Questions, answered plainly.
RTA is supplied as laboratory research material only. It is 21+ only, not for human consumption, and not for veterinary use.
The product page lists catalog lot, appearance and storage notes for RTA. Available original reports are labelled by sample; matching current certification is unavailable where the compound, lot or amount differs. A heavy-metals screen does not measure purity or confirm identity.
Follow the label and your laboratory's written procedures. Do not treat a historical sample report as current lot documentation. This page repeats 2-8 C storage guidance and light-protection notes before checkout.
RTA is the store code for this freeze-dried research reference peptide. The available historical sample report does not establish identity, purity or release status for the listed lot. It is supplied for laboratory research only, not for human use.
The catalog lists lot RTD-2506. The historical report covers 15 mg, lot FL20260410-RETA-15, not the listed 10, 20 or 30 mg items. The lab report on file for RTA is a Janoshik heavy-metals screen, which reports arsenic, cadmium and mercury as not detected. It does not measure purity and does not confirm identity. Compare any available report with the vial label before lab intake.
The catalog lists storage at 2-8 C, protected from light; the historical report does not establish storage conditions for this lot. RTA is supplied as a freeze-dried powder, so it stays in that form until a lab chooses to work with it. Check the vial label and the receiving laboratory's procedures. This is handling context only, not a preparation or use instruction.
Add the size and quantity you want to your cart and check out. Instead of paying by card, you'll get an emailed invoice with our bank details - pay by bank transfer, quoting the reference. Once the payment clears we pack your order and send it, and you'll get a tracking email. A faster transfer (PayID or Osko) gets things moving sooner.
The available historical sample was tested by Janoshik. The lab report on file is a Janoshik heavy-metals screen: it reports arsenic, cadmium and mercury as not detected. It does not measure purity, does not confirm identity, and does not test for bacterial residue. The report covers its named sample lot, which differs from the listed catalog lot.
It ships from our base in Perth via Australia Post or CouriersPlease, in plain packaging with nothing identifying on the outside, once your payment has cleared. You'll get a tracking email, and the tracking link shows the delivery estimate for your address. On arrival, store it in the fridge at 2-8 C and keep it out of light.
Our purity guarantee applies to the purity stated on the Certificate of Analysis (COA) supplied with your order or available on request. If, within 30 days of your order, an independent lab re-tests that batch and finds it below that purity, we refund the order in full - no need to return the vial.
No. It's supplied strictly as reference material for laboratory research - not a medicine, supplement, or food, and not for people or animals to take. The research described on this page is about the molecule in published studies, not about a Form Labs product.
