RTA (20mg)
$245.00
RTA15 is the most advanced peptide in metabolic science—a revolutionary "triple agonist" that activates GLP-1, GIP, and Glucagon receptors simultaneously. While GLP-1 and GIP work synergistically to silence appetite and optimize insulin sensitivity, the addition of Glucagon sets RTA15 apart by actively increasing resting energy expenditure. This means it doesn't just lower caloric intake; it ramps up the body's metabolic furnace to oxidize fat more efficiently. The result is a comprehensive approach to body recomposition, offering superior glycemic control, rapid weight reduction, and cardiovascular support in one potent protocol.

Product Description
Triple-Agonist Power: GLP-1 + GIP + Glucagon
RTA15 is the world’s first “triple-G” agonist, targeting three distinct metabolic receptors simultaneously. While GLP-1 and GIP work to suppress appetite and optimize insulin, the addition of Glucagon is the game-changer. This third mechanism specifically targets energy expenditure, signaling the body to burn more calories at rest. This synergy creates a metabolic environment where fat loss occurs significantly faster and more efficiently than with dual-agonist therapies.
Increase Resting Metabolic Rate
The defining advantage of RTA15 over older peptides is its ability to increase Resting Energy Expenditure (REE). By activating glucagon receptors in the liver and adipose tissue, it promotes thermogenesis—literally turning up your body’s internal heat to oxidize fat stores. This means you aren’t just eating less; you are actively burning more energy every hour of the day, preventing the metabolic slowdown often associated with rapid weight loss.
Mobilize Stubborn Visceral & Liver Fat
RTA15 has shown unprecedented efficacy in targeting visceral fat, particularly in the liver. Excess liver fat is a primary driver of metabolic dysfunction and insulin resistance. By aggressively oxidizing these deep adipose depots, RTA15 doesn’t just improve your waistline; it profoundly restores metabolic health and liver function markers, addressing the root cause of weight gain rather than just the symptom.
Superior Nutrient Partitioning & Muscle Preservation
Rapid weight loss often comes at the cost of muscle tissue. RTA15 unique mechanism helps improve nutrient partitioning—directing energy toward muscle maintenance while prioritizing fat for fuel. When combined with adequate protein intake, this supports a true “recomposition” effect, allowing users to drop significant body fat percentage while retaining the lean muscle mass essential for a healthy, sculpted physique.

Our Guide to
Intramuscular Injection
Gather Your
Equipment
If you’re new to the process of injection, ensure you have all the essential supplies at your disposal before commencing. This includes the injectable substance, a sterile disposable syringe and needle, alcohol wipes, a secure container for proper needle disposal, cotton balls or gauze pads for cleansing, and optionally, a mirror for self-injection, if required. Having these items readily available ensures a seamless and uninterrupted injection process. It is vital to prioritize safety and efficiency to position your body optimally for health and longevity.
Compound
Extraction
Once all the necessary materials are assembled, proceed to extract the substance from the vial. Keep the vial upright, slowly pull back the plunger to draw the prescribed dosage into the syringe. Be careful to extract the exact amount prescribed, adhering to the instructions provided by your healthcare professional. After filling the syringe, gently tap it to dislodge any air bubbles. If any air bubbles are present, push the plunger up slightly to eliminate them, ensuring that only the specified amount of the substance is in the syringe. Familiarize yourself with the proper injection depth before advancing to the next step.
Preparation Before
Injection
Before administering your injection, choose a well-lit and clean area. Prior to starting, wash your hands thoroughly with soap and water to maintain hygiene. Once your workspace is prepared, ready the injection site, which could be the buttocks (gluteal muscles), thighs, or upper arm (deltoid muscle). Seek guidance from your healthcare provider on the appropriate site. Regardless of the chosen site, use an alcohol wipe to cleanse it, removing any dirt, oils, or contaminants. Allow the area to air dry completely after the cleaning process.
Compound
Administration
With the syringe prepared, it’s time to administer the injection. Hold the prepared syringe and carefully insert the needle into the designated injection site. Once the needle is inserted at the correct depth, pull back slightly on the plunger to confirm that you haven’t hit a blood vessel. If blood appears in the syringe, retract the needle and attempt again with a new needle tip. Assuming there is no blood, steadily and slowly push the plunger to inject the substance. Take your time to ensure a controlled and comfortable administration of the injection. After the full dosage is administered, withdraw the needle from the injection site.

Usage Guidelines
01
Draw 1.5ml of Bacteriostatic Water USP from the vial.
02
Carefully inject the Bacteriostatic Water into the RTA15 vial. Aim the stream along the side of the vial, avoiding direct contact with the lyophilized powder.
03
Gently swirl the vial to dissolve the powder completely. Ensure the solution becomes clear. Do not shake the vial vigorously.
04
After reconstituting with 2 mL of bacteriostatic water, the concentration is 10 mg per mL. At this dilution, every 10 units on a standard insulin syringe provides exactly 1 mg of RTA20.
05
The prepared solution can be administered subcutaneously (Sub Q) in the lower abdominal fat area.
06
Once reconstituted with Bacteriostatic Water, the RTA20 solution should be stored in a refrigerator. Use the mixed solution within 60 days to ensure potency and effectiveness.
When to Take it
When to Take
Retatrutide is administered once weekly. Because it has a long half-life, it is best to choose a specific “Pin Day” (e.g., Sunday morning) and stick to it. It can be taken with or without food, though many researchers prefer morning administration to monitor their appetite suppression throughout the day.
Administration Tips
-
Start Low, Go Slow: It is highly recommended to start as low as 0.5mg to 1mg for the first week or two. Slowly increase your dose over time to find your personal “sweet spot” for results and comfort.
-
Tapering Off: Rather than stopping “cold turkey,” it is best to slowly lower your dosage over a few weeks before coming off completely. This helps your metabolism and appetite signals adjust gradually, making it easier to maintain your results.
-
Hydration: Ensure you are drinking plenty of water, as metabolic shifts can increase your hydration needs.
Retatrutide (20mg) Dosage Guide
After reconstituting this 20mg vial with 2ml of Bacteriostatic Water, the concentration is exactly 10mg/ml. Using this dilution, every 10 units on your syringe equals 1mg of peptide.
-
Introductory Phase (0.5mg – 1mg): Draw to the 5 or 10-unit mark.

Seek Guidance From a Medical Professional
Before contemplating the usage of anabolic steroids, it’s essential to seek advice from a qualified healthcare professional. They can evaluate your general health, discuss possible risks and advantages, and offer personalized guidance based on your specific needs.
Get High-Quality Items From Trusted Sources
Make sure to procure anabolic steroids from trustworthy sources to reduce the likelihood of receiving counterfeit or tainted products. Only buy from reliable suppliers who adhere to quality control standards and have a favorable reputation within the community.
Start Slow and Progress Gradually
If you opt to incorporate anabolic steroids, it is recommended to initiate the regimen with the smallest effective dosage. Incrementally raise the dosage if required, while closely monitoring your body’s reactions and any potential adverse effects.
Prioritize Proper Post-Cycle Therapy
Following the conclusion of a steroid cycle, it’s crucial to engage in a thorough post-cycle therapy routine. This aids in restoring natural hormone production, minimizing side effects, and preserving overall health and well-being.
