R3TA (LY3437943) is a synthetic substance consisting of 39 amino acids, developed for metabolic pathway research. It is classified as a triple agonist, meaning research suggests it activates three receptor types simultaneously:

Research suggests R3TA's multi-receptor activity makes it a useful tool for investigating:
● Blood sugar regulation pathways
● Energy expenditure mechanisms
● Appetite signaling systems
● Lipid processing in the liver
● Cholesterol pathway activity

Your pen comes ready to use

What's Included:

• Pre-filled R3TA research pen (10mg)
• Sterile pen needles
• Alcohol swabs

Step 1: Prepare

Wash hands thoroughly. Remove the pen cap and attach a new sterile needle by twisting it onto the pen tip until secure.

Step 2: Prime the Pen (First Use Only)

Dial to the smallest dose setting. Hold pen needle-up and press the injection button until a small droplet appears at the needle tip. This removes air from the cartridge.

Step 3: Select Your Research Amount

Turn the dose dial to your desired amount. The pen will click with each unit increment.

Step 4: Administer

Clean the research site with an alcohol swab. Insert the needle and press the injection button fully. Hold for 5–10 seconds before withdrawing.

Step 5: Dispose Safely

Remove and discard the needle in a sharps container after each use. Replace the pen cap for storage.

💡 Store your pen refrigerated (2–8°C) once opened. Use within 30 days of first use.

Our pens are manufactured to maintain stability during shipping and storage. Unlike lyophilized vials, pre-filled pens require refrigeration upon receipt.

Storage Guidelines:

Unopened - Refrigerated at 2–8°C (36–46°F)

After first use - Refrigerated, use within 30 days

Never freeze - Freezing may damage the peptide solution

⚠️ Keep pens away from direct light and heat. Do not use if solution appears cloudy or contains particles.
