Product questions

What is GLP-3 (RT)?

GLP-3 (RT) is our retatrutide research peptide, offered in 15 mg and 30 mg vials. Each strength has its own batch record and quantity result.

Who tests this product?

Independent U.S. laboratories perform our testing, and each report names the lab that issued it. Check the Lab Results page for the matching lot; testing-in-progress cards are not completed results.

How should I store it?

On arrival, refrigerate unopened lyophilized vials at 2–8°C for short-term storage. For longer-term storage, −20°C or below is preferred. Keep vials sealed, away from light and moisture, and avoid repeated freeze–thaw cycles.

How do I verify the COA?

Match your branded vial’s lot number and cap color using Verify Product, then check the report directly with the issuing laboratory.

Can I return a vial?

Yes. Unopened vials can be returned within 30 days of delivery for full store credit, or a GCash refund minus a 30% restocking fee. Contact us first for return instructions; return shipping is paid by the buyer unless the return is due to our error.

Can I read the COA before ordering?

Completed COAs are published on Lab Results before a batch is released. The current cards show testing in progress; they are not completed reports. Once published, check the product, strength and lot before relying on the results.

What if the QR code or report link does not open?

Enter the full lot manually on Verify Product. For a missing or broken report, email support@morrispeppy.com with the lot and photos of the label and cap. A broken link alone does not prove a report is fake.

What should I check when my parcel arrives?

Compare the product, strength and quantity with your order and batch-code packing slip. Check the vial seals and glass, then match the lot and cap color to the batch record. Film the unboxing, and keep the video and the packaging if you need to contact us about damage or a mismatch.

Does a broken powder cake mean the product is damaged?

A freeze-dried cake can break into loose powder during handling. Its shape alone cannot establish purity, quantity or contamination. Check the seal and glass for damage and use the matching batch COA to review the test results.

GLP-3 (RT): specifications, testing and price

01

About Retatrutide (GLP-3 (RT))

Retatrutide is a synthetic, lipidated peptide of 39 amino-acid residues. Its backbone is based on the glucose-dependent insulinotropic polypeptide (GIP) sequence, with non-coded residues such as α-aminoisobutyric acid (Aib) and a C20 fatty diacid side chain attached through a linker. In the published literature this acylation is described as promoting albumin binding and a long plasma half-life in study models.

Retatrutide is reported as a single-molecule agonist at three class B G-protein-coupled receptors: the GIP receptor, the glucagon-like peptide-1 (GLP-1) receptor and the glucagon receptor. For this reason it is often called a triple agonist, and the store code name GLP-3 (RT) refers to this three-receptor profile.

Research status: retatrutide is an investigational compound that has been evaluated in clinical trials. It is not an approved medicine, and the material listed here is supplied only as a reference standard for laboratory work.

For laboratory research use only. Not for human or animal consumption.

03

Quality testing for this product

Every newly received batch of GLP-3 (RT) is sent for testing at an independent U.S. laboratory. Five vials are pulled at random from a single production run, and each batch goes through up to 10 distinct checks before release:

  • Purity by HPLC
  • Quantity (content per vial)
  • Identity by spectrum analysis
  • Solubility on reconstitution
  • Endotoxin (LAL assay)
  • Multi-vial conformity
  • Fentanyl screening
  • Product integrity (vial seal and container check)
  • Heavy metals (arsenic, cadmium, lead, mercury)
  • Sterility

The first GLP-3 (RT) 15 mg and 30 mg lots failed sterility (USP <71>) and were rejected and disposed, so none was sold. Their reports are on Lab Results. New batches are coming, and their results will be published before they ship. Completed reports are posted on Lab Results before a batch ships, and you can match your vial’s lot number and cap color on Verify Product. See how we test.

05

Delivery and receiving

Orders ship within the Philippines in a tamper-evident inner pouch, with the batch code on the packing slip. On arrival, check the seals, strength and lot against your order. See Shipping & Delivery for courier estimates. Unopened, unaltered vials bought from morrispeppy.com can be returned within 30 days of delivery for full store credit, or a GCash refund minus a 30% restocking fee under our 30-day returns.
