HOW MUCH YOU’LL NEED

SUGGESTED ORDER AMOUNT

A common approach 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 2.0 mL of Bacteriostatic Water USP.

02

Slowly inject the Bacteriostatic Water into the RTA20 vial, aiming the stream down the side of the vial and not directly onto the powder.

03

Gently swirl until the powder is fully dissolved and the solution becomes clear. Do not shake aggressively.

04

Once mixed, the concentration will be 20 mg per vial, equating to 1 mg (1000 mcg) per 10 units on a standard insulin syringe.* (Reminder: 100 units = 1 mL = 10 mg of Retatrutide — Since the vial contains 2 mL total, the vial holds 200 units = 20 mg total.)

05

Administer subcutaneously (SubQ). Injection sites can be rotated, with the lower abdominal fat being the most common and easiest location.

06

After reconstitution, store the vial in the refrigerator. Use within 60 days to maintain potency.

WHEN TO TAKE it

Retatrutide is typically injected once weekly, with timing based on convenience and consistency. Due to its long half-life and sustained activity, daily dosing is not required. Most users choose a fixed day each week to maintain steady levels and keep things simple.

It can be taken with or without food. Some people prefer dosing after a light meal to reduce potential gastrointestinal side effects such as nausea.
Morning dosing tends to align well with appetite and metabolic regulation throughout the day, though evening dosing is also fine if it fits your routine better.

If you’re just starting, beginning at a lower dose and increasing gradually helps minimize side effects and allows your body to adapt.

RECOMMENDED SCHEDULE

  • Week 1: 1 mg
  • Week 2–3: 2-3 mg
  • From there, adjust upward only if needed based on response and tolerance.

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.

From Mounjaro to Reta.
I transitioned from Mounjaro to Pacific's Reta a couple of months ago, and it's been working great. A heads-up for anyone making the switch: I was taking 10 mg of tirzepatide and thought it would be best to start Reta at a low dose (2.5 mg) and gradually titrate up to 10 mg. In hindsight, I don't think that was necessary. In addition to a solid product, the delivery and comm has been great.

New to the peptides
So far so good, I’m an Ozempic user of the last couple of years and decided to try something different and I did some research so I went with the RTA! I will say though that the baceriostatic water (same exact ingredients) is half the cost on Amazon. I also would like to point out that I originally messaged you guys to ask about the product (twice) and was ignored, only when I made an almost 400$ purchase was I able to get any response, which was with regards to my order. I also feel that you instructions should be way more detailed for mixing and dosing, my daughters are BOTH RNs and one also has her CCN and it took them a few minutes to figure out the instructions, that is not good for the average person. Otherwise, the product came in a timely fashion and we shall see how it works!

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.
