What is Retatrutide?

Retatrutide is a triple-action research peptide now gaining attention in Canada as a powerful weight loss solution. Unlike Ozempic and Wegovy, it activates GLP-1, GIP, and Glucagon receptors — accelerating fat loss, metabolic repair, and appetite control.

Most popular weight loss injections (like Ozempic) only target GLP-1. Retatrutide targets three fat-burning pathways at once.

In clinical trials, subjects experienced an average weight loss of 24.2% over 12–18 weeks—outperforming Ozempic, Wegovy, and Mounjaro.

What to Expect

  • Reduced appetite in 7–10 days

  • Better insulin sensitivity

  • Decreased cravings

  • Mild side effects (nausea, constipation, dry mouth) often fade quickly

Why It’s Different

✅ Triple-action targeting (GLP-1, GIP, Glucagon)
✅ Stronger outcomes in clinical trials
✅ Better tolerance profile
✅ Once-a-week dosing
✅ Available for research use via Zempra Labs

How Retatrutide Works

A triple-pathway breakthrough for fat loss, insulin sensitivity, and metabolic repair.


What Makes It Different
Retatrutide is a breakthrough peptide that activates GLP-1, GIP, and glucagon receptors—making it one of the most advanced compounds ever developed for fat loss and metabolic control.
Most popular weight loss injections (like Ozempic) only target GLP-1. Retatrutide targets three fat-burning pathways at once, creating a more comprehensive response.

What to Expect in Early Research
• Reduced appetite within 7–10 days
• Improved insulin sensitivity
• Decreased cravings for sugar and starch
• Mild side effects (nausea, dry mouth, constipation) that fade quickly

Why It’s a Game Changer
Triple-action targeting of GLP-1, GIP, and Glucagon
24.2% average weight loss in early clinical trials
Outperformed Ozempic, Wegovy, and Mounjaro
Better tolerance profile in most subjects
Once-a-week dosing

Frequently Asked Questions

1. What is Retatrutide?

Retatrutide is a research peptide designed to activate GLP-1, GIP, and glucagon receptors—promoting weight loss, metabolic repair, and appetite control through a triple-action mechanism. It is not approved for human consumption and is intended for research purposes only.

2. What does "activating GLP-1, GIP, and glucagon receptors" mean?

These are three important pathways your body uses to regulate weight, blood sugar, and fat burning:

  • GLP-1 (Glucagon-like peptide-1):
    Reduces appetite, slows digestion, and controls blood sugar after meals.

  • GIP (Gastric inhibitory polypeptide):
    Supports better insulin release and helps the body use energy rather than storing fat.

  • Glucagon receptor:
    Helps the body break down stored fat and turn it into usable energy, enhancing fat loss.

Retatrutide activates all three simultaneously for deeper fat loss, faster metabolism repair, and stronger appetite control compared to single-pathway drugs like Ozempic.

3. How does Retatrutide differ from Ozempic or Mounjaro?

Unlike Ozempic (which targets only GLP-1), Retatrutide targets GLP-1, GIP, and glucagon receptors together.
In early clinical trials, Retatrutide delivered stronger and faster weight loss, with an average body weight loss of 24.2% over 12–18 weeks—outperforming Ozempic, Wegovy, and Mounjaro.

4. What comes in the Zempra Labs Starter Pack?

Each Starter Pack includes:

  • 10mg sealed vial of Retatrutide (research-grade)

  • 10x 31G insulin syringes (single use)

  • 1x 3mL draw syringe (for mixing)

  • Sealed 5mL bacteriostatic water vial

  • 16 alcohol prep pads

  • Full reconstitution and dosing instructions

You’ll receive printed instructions explaining:

  • How to reconstitute 10mg Retatrutide with 1mL bacteriostatic water

  • How to measure 10 insulin units = 1mg

  • How to administer a weekly 2mg dose (20 units) easily

  • Best storage practices for stability and potency

5. How much Retatrutide do most researchers administer weekly?

Most researchers start with 2mg per week.
With 1mL of bacteriostatic water added to a 10mg vial:

  • 1mg = 10 insulin units

  • 2mg = 20 units weekly

  • A single vial typically lasts 5 weeks at standard research dosing.

  • Improved insulin sensitivity

  • Stabilized blood sugar levels

  • Targeting of hard-to-lose visceral (belly) fat

  • Reduced food cravings

  • Enhanced mood and motivation

All benefits are investigational and based on ongoing studies.

13. How long should a research cycle with Retatrutide last?

Typical research cycles last 12 to 18 weeks, based on published study data.
Some protocols extend longer depending on study goals and subject response.

14. Will instructions for reconstitution and dosing be provided?

Yes.
Your Starter Pack includes printed instructions showing:

  • Add exactly 1mL bacteriostatic water to your 10mg vial

Dosing is typically once-weekly subcutaneous injections (under the skin).
With 1mL bacteriostatic water:

  • 1mg = 10 units

  • 2mg = 20 units weekly

  • Administer using the provided 31G insulin syringes following included guidance.
