HOW MUCH YOU’LL NEED

SUGGESTED ORDER AMOUNT

A good rule of thumb is 2 vials per person, which will last approximately 2.5–3 months, depending on your final weekly dose.

 

 

Dosage (Male)

1–12 mg once weekly (titrated)

Dosage (Female)

1–12 mg once weekly (titrated)

Dosage Frequency

Once per week

Dosage Type

Subcutaneous Injection

MIXING & 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

Once mixed, the concentration will be 15mg RTA15 per vial, equating to 1mg (1000mcg) per 10 units on an insulin syringe. Remember, 100 units on the syringe equals 1ml, corresponding to 10mg of RTA15.

05

The prepared solution can be administered subcutaneously (Sub Q). Injections can be either site-specific or administered in the lower abdominal fat area.

06

Once reconstituted with Bacteriostatic Water, the RTA15 solution should be stored in a refrigerator. Use the mixed solution within 60 days to ensure potency and effectiveness.

WHEN TO TAKE it

RTA15 is typically administered once weekly, with timing chosen for convenience and consistency. Because of its long half-life and sustained action, there’s no need for daily dosing. Many users select a set day each week to maintain steady therapeutic levels and simplify adherence.

It can be taken with or without food; however, some individuals find it more comfortable to administer after a light meal to reduce potential gastrointestinal side effects such as nausea. Given its ability to help regulate glucose, appetite, and metabolic activity throughout the week, timing the injection earlier in the day may align better with active hours, while evening dosing can work well for those who prefer a routine before bedtime. If beginning therapy, starting with a lower dose and gradually increasing—per healthcare provider guidance—can help the body adjust and minimize side effects.

As with all medications, consistency is key. Choose a weekly schedule that fits seamlessly into your lifestyle to get the full benefit of RTA15 triple-pathway metabolic support.

 

 

RECOMMENDED SCHEDULE

  • Week 1: 1 mg
  • Week 2–3: 2-3 mg
  • From there, you will be able to feel what is working, and can increase your levels accordingly.

Break Free From Stubborn Weight

RTA targets key metabolic pathways to help the body shed resistant fat stores. By improving insulin response and reducing appetite, it makes it easier to break past weight loss stalls and continue progressing toward long-term health goals.

Restore Balance, Inside and Out

This innovative therapy does more than manage weight—it supports whole-body wellness. RTA promotes healthier blood sugar levels, reduces metabolic strain, and helps restore balance, leading to improved energy, vitality, and overall quality of life.

Our Vision

10+ Years of Peptide Expertise

At Pacific Peptides our mission is to offer you access to the highest quality peptides, helping you achieve the physique and fitness goals you’ve always dreamed of. Each of our peptides is designed to enhance overall well-being, boost performance, and promote vitality. With over ten years of experience in peptide formulation, Pacific Peptides offers a wide range of products to help you reach your full potential.

Sustainable Results That Last

RTA is designed for lasting change, not quick fixes. By addressing underlying metabolic dysfunction, it supports gradual, steady improvements in body composition and health markers—helping you achieve results that are maintainable for the long term.

Energy to Live Fully

RTA supports enhanced metabolic health and weight management by activating multiple hormonal pathways. It helps improve energy levels, support lean body composition, and boost overall vitality—empowering you to feel more confident, active, and in control of your wellness journey.

Incorporate RTA Into a Stack

RTA is sometimes combined with peptides like CJC-1295 (with DAC) to complement its effects. RTA works primarily on metabolic pathways to support weight management and blood sugar regulation, while CJC-1295 promotes the release of growth hormone, which may aid in fat reduction, lean muscle preservation, and recovery. Together, this combination is explored for its potential to enhance body composition and overall performance. As with any protocol, it’s important to use careful dosing, make gradual adjustments, and follow medical guidance to ensure safety and effectiveness.

First time taking reta
I am only a week and a half into using this peptide. I do not have any side effects from using it but also too soon to say I am seeing results. My appetite is still high and no weight loss as of yet. Hopefully the next few weeks I will start seeing some results.

Easy on the Gut
I tried Wegovy last year and had some pretty serious gut issues as a side effect. I was told to "tough it out," and eventually they would go away, but they did not. Now, on Reta, I am not experiencing those side effects, and it's totally reduced my appetite. I feel great, and it is easy to administer. I did get some guidance from Emily in Customer Support on how much to take and when (thanks Emily), so if you are unsure, contact them for more help. All in all, I am super happy!

Safe Disposale of Needle Tips and Syringes

Ensuring the proper disposal of utilized syringes and needles is crucial for the safety of yourself and those around you. Once used, promptly deposit the syringe and needle into a designated sharps container. Avoid recapping the needle to prevent unintentional needle pricks. Familiarize yourself with the regulations in your local area concerning the appropriate disposal of medical waste. Numerous regions have specific guidelines for discarding sharps containers, and adhering to them is vital to safeguard both your community and the environment.

Side Effects + Considerations

RTA is generally well-tolerated, although gastrointestinal side effects are frequently reported during dose escalation. These may include nausea, diarrhea, vomiting, constipation, and reduced appetite. Some individuals may also experience fatigue, mild dizziness, or reactions at the injection site. Rare but more serious risks include pancreatitis and gallbladder-related complications. As with any investigational medication, RTA should only be used under medical supervision, with gradual dose adjustments to help minimize side effects.
