Retatrutide in Malaysia: Is It Approved? (Updated Oct 2026)

No. Retatrutide ("Reta") is not registered in Malaysia and is not approved anywhere in the world. It is still in clinical trials, so any "Reta" pen sold here is unregistered and illegal to sell.

Already bought or used Reta? What to do now

No judgement. Many people ask us this.

Seek medical care urgently if you have:

  • Severe or persistent abdominal pain
  • Repeated vomiting, or you can't keep fluids down
  • Signs of dehydration
  • Yellowing of the skin or eyes
  • Swelling, redness or pus at the injection site, or fever

List pending final review by the medical team.

You're not alone, and you don't need to feel embarrassed. Here's what to do:

  1. Stop using it, and don't share pens or needles.
  2. Talk to a doctor. Be honest about what you used, how much and how often, and bring the packaging.
  3. Watch for the urgent symptoms listed above.
  4. Report the product or seller to KKM (Pharmacy Enforcement), and report side effects through NPRA's adverse drug reaction reporting.

Risks of "pen kurus" sold online

Pens and vials sold on social media or marketplaces carry risks that have nothing to do with the real drug:

  • No guarantee what's inside. It could be a different substance, or nothing at all.
  • Wrong doses. No doctor sets or adjusts the dose.
  • Sterility problems. Non-sterile products can cause infection.
  • KKM warnings. KKM has warned the public against these products and removed hundreds of listings.
[1][6]

Side effects of retatrutide

Even in controlled trials (TRIUMPH-1), side effects were common:[4]

  • Nausea: 28.6–42.4% (vs 14.8% on placebo)
  • Diarrhoea: 25.2–34.1%
  • Constipation: 23.8–26.1%
  • Vomiting: 10.6–25.3%
  • Dysesthesia (abnormal skin sensation): 5.1–12.5% (vs 0.9%)

Up to 11.3% stopped treatment because of side effects at the highest dose.

Extra risks from unregistered products

Wrong or unknown dose, contamination, infection from non-sterile injection, fake or substituted ingredients, and no doctor to spot complications early. KKM warns that using such products "without proper medical evaluation and monitoring can cause adverse effects and serious complications."[1][6]

But the trial results look amazing. Why not?

The results are impressive, and that is exactly why fakes are everywhere. In Lilly's TRIUMPH-1 Phase 3 trial (May 2026), 2,339 adults without diabetes lost an average of 19.0% (4 mg), 25.9% (9 mg) and 28.3% (12 mg) of their body weight over 80 weeks.[4] TRIUMPH-2 and TRIUMPH-3 reported up to 20.8% and 22.6%.[5]

These results describe Lilly's drug, used under medical supervision. They say nothing about what is inside a pen bought online.

What is Reta (retatrutide)?

Retatrutide is an investigational weight-loss medicine made by Eli Lilly.[4] It is called a "triple agonist" because it acts on three hormone receptors involved in appetite and blood sugar: GLP-1, GIP and glucagon.

On TikTok and Facebook it is often shortened to "Reta". Sellers commonly label it a "research peptide" or "research chemical". That label means the product is not a pharmaceutical made for human use.[1][6]

"Reta" can also refer to unrelated things, such as a company name or a stock ticker. This page is only about the weight-loss drug.

Frequently asked questions

What is Reta?

Reta is the social media name for retatrutide, an experimental weight-loss injection made by Eli Lilly. It acts on three hormone receptors (GLP-1, GIP and glucagon). It is still in Phase 3 clinical trials, is not approved anywhere in the world, and is not registered in Malaysia.

Is Reta approved in Malaysia?

No. Retatrutide is not registered with Malaysia's Drug Control Authority, and it has not been approved in any other country either. The Ministry of Health says it cannot be legally sold, imported, advertised or supplied in Malaysia. Any product sold as Reta here is unregistered.

Is it illegal to buy or use Reta in Malaysia?

Selling, importing, supplying and advertising unregistered medicines such as retatrutide is illegal in Malaysia under the Sale of Drugs Act 1952 and related laws. Because the contents of these products can't be verified, using them also carries real health risks. Speak to a doctor about safe options instead.

When will retatrutide be available in Malaysia?

Not yet, and there is no confirmed date. Lilly plans to submit retatrutide to the US FDA in the first quarter of 2027. Even if it is approved abroad, it would still need to be registered with Malaysia's Drug Control Authority before it could be legally sold here.

Reta vs tirzepatide vs semaglutide: what's the difference?

Semaglutide acts on one hormone receptor (GLP-1) and tirzepatide on two (GLP-1 and GIP); both are approved medicines. Retatrutide acts on three, adding glucagon, and is still investigational and not approved anywhere. Which approach suits you is a medical decision made with a doctor.

Where can I buy Reta in Malaysia?

Nowhere legally. Retatrutide is not registered in Malaysia, so no pharmacy, clinic or online seller can legally sell it. Anything offered as Reta is an unregistered product. A doctor can talk you through registered options that may suit you.

Is "Reta peptide" the same as retatrutide?

Not necessarily. Products sold as "Reta peptide" are usually labelled research chemicals that are not made for human use. Their contents, dose and sterility cannot be verified, so there is no way to know whether a vial actually contains retatrutide, a different substance, or contaminants.

Is cucuk Reta safe for weight loss?

No, not as sold in Malaysia. Even the genuine drug caused frequent nausea, vomiting and diarrhoea in supervised trials. Unregistered pens add unknown doses, possible contamination and infection risk, with no doctor monitoring you. A doctor-led weight-loss plan is the safer route.

Reta vs Mounjaro: what's the difference?

Tirzepatide (Mounjaro) acts on two receptors, GLP-1 and GIP, and is an approved medicine. Retatrutide acts on three, adding glucagon, and is still investigational. Whether any medicine suits you depends on your health history, so the choice should be made with a doctor.

What are the side effects of Reta?

In the TRIUMPH-1 trial, common side effects were nausea, diarrhoea, constipation, vomiting and abnormal skin sensations, and up to 11.3% stopped at the highest dose. Unregistered products add risks such as the wrong dose, contamination and infection. Seek urgent care for severe abdominal pain or repeated vomiting.

How do I check if a weight-loss injection is registered?

Search the product name on the NPRA website's Product Search and look for a MAL registration number on the pack. Genuine products carry a FarmaTag hologram, which you can verify with the MyUBAT app. If any of these are missing, treat the product as unregistered.

I've used Reta. What should I do?

Stop using it, and don't share pens or needles. Talk to a doctor honestly about what you used, how much and how often, and bring the packaging. Watch for warning signs such as severe abdominal pain or repeated vomiting, and report the product to KKM.
