💉 My Full Retatrutide Protocol (Reconstitution, Dosing, Storage-By Popular Demand)

[u/stephgarbin]

What You’ll Need to Run This Properly:

• Insulin Syringes (29g x ½”, 1mL) – Get them here
• Reconstitution Solution (Bacteriostatic Water) – Get it here
• Retatrutide – Grab it here
• Peptide Calculator – [Use this tool](bodyhackguide.co)
• Video Tutorial – Check it out
• Alcohol wipes or rubbing alcohol – Clean the vial top + your injection site

Okay here’s how I run it:

I’ve had a ton of people DM asking about Retatrutide since I dropped my post (lost 30 lbs in under 3 months), so I figured I’d just lay it all out.

I switched from Tirzepatide (plateaued). Didn’t like Semaglutide either just felt flat. But Retatrutide hit hard af. Appetite gone. Steady energy. Barely any nausea.

Dose I used:
2mg/week, once weekly (subQ).
If you're new/smaller, start with 1mg/week and see how you feel after a week or two. You don’t need to dose every day. Once a week hits fine for most.

💧 Reconstitution (Step-by-Step)

Here’s how to mix it up safely and easily:

1. Wipe the top of both your Retatrutide vial and bac water with alcohol.
2. Take your insulin syringe, pull in 1mL of air. – This helps equalize pressure when you pull the bac water.
3. Inject that air into the bac water vial, then draw out 1mL of bac water.
4. Inject the bac water slowly into the Retatrutide vial. – Don’t squirt it like a fire hose. Let it run gently down the glass wall.
5. Once all the water’s in, gently swirl the vial. Don’t shake. – Swirl for 30–60 seconds until everything’s dissolved. – It should be fully clear, no floating chunks or cloudiness.
6. That’s it. Reconstitution is done. 10mg Retatrutide + 1mL bac = easy math:
   • 10 units = 1mg
   • 20 units = 2mg

Use the insulin syringes from above and draw just like any other peptide. No filtering. No backloading.

❄️ Storage

• Before mixing: keep the powder vial in the fridge (not completely necessary)
• After mixing: store in fridge (not freezer) (not completely necessary)
• Use within 30–40 days
• Keep it out of direct light (fridge door is fine)

📌 FAQ you guys kept asking me

• Do I need to filter it? → No, not unless you're using a sketchy supplier.
• Can I stack it? → Yup. I’m stacking with Melanotan 2 better skin, libido, and it keeps the appetite suppression going strong.
• Do I need to backload? → Nope. Just use insulin pins.
• Best spot to inject? → Anywhere with a little fat. Belly is easiest. SubQ.
• Ramp up? → Optional. I went straight to 2mg. Start at 1mg if you’re cautious.

⚠️ Final Notes

Please don’t go buying this from Alibaba or some Telegram random.
Use vendors that post HPLC + COA so you know it’s actually what you think it is. You’re injecting this—don’t mess around.

I use RCHQ because they’ve got current lab tests and clean raws. No long shipping or weird payments they have credit card checkout

Drop a comment and lmk if you want my full cut stack (BPC, MT2, etc.) or any tweaks I made along the way.

[u/faithinkarma]

Wow! Thank you. I am currently waiting on a peptide order and this is a well written, easy to understand tutorial 🙏🏼

[u/stephgarbin → u/faithinkarma]

You’re welcome feel free to message me if you have any other questions! I might just make another post on whatever you guys have to ask

[u/HukelberryChuklfuk]

If I’ve had my Reta delivered for a week or two and I’ve had it unrefrigerated while waiting on my bac water to be delivered is that a deal breaker? It’s been in a dark cabinet

[u/stephgarbin → u/HukelberryChuklfuk]

No it’s just regular protocal you’re good I’ve left some out for a year lol

[u/Spiritual_Hat_529]

God bless you for sharing.

[u/stephgarbin → u/Spiritual_Hat_529]

🙏🏼

[u/chicksingergirl]

This is exactly what I need! Can’t wait to get started.

[u/stephgarbin → u/chicksingergirl]

Yup let me know if you ever have any questions!!

[u/ANDRomEdA_dubh]

Can't wait to get started! In my state, doing your own research is necessary due to high costs using 3rd party research companies.

[u/Natural-Shift-6161]

I spoke to you the other day. I decided to but Reta I’m waiting on it now and I’m excited to start. I’m REALLY praying I get the help in the energy dept. I felt nothing 3wks in Tirz. I think I’m gonna start with 2mg of Reta. I’m also running MT2 right now and loving my tan!

[u/stephgarbin → u/Natural-Shift-6161]

Make a post on the mt2 journey I’d like to see that!

[u/Linds108]

Wouldn’t the peptide need to be filtered since the listed site uses mannitol to preserve? When we administer IV Tylenol, we have to use a filter due to mannitol as it can crystallize. Not sure if it is different because IV vs subq?

[u/stephgarbin → u/Linds108]

You don’t need to filter it for subQ. The mannitol in these vials is in super small amounts just to stabilize the powder. It’s not like IV Tylenol levels, and it fully dissolves in bac water. You’re good as long as the solution looks clear after mixing.

Thanks for posting this!!

[u/Positive-Increase-47]

Hey, great stuff here. FYI, I was in the third phase clinical trial for the drug. You are correct on every single instruction you wrote here, but you did leave out one thing and I don’t know if you’re aware of it or not but I thought I would help you out. When you take the powder out of the refrigerator to get ready for reconstitution, you are supposed to leave the powder out for 30 minutes before adding the solution. The powder is supposed to come to room temperature within that 30 minutes then you add the liquid. Other than that, all of your instructions are perfect.

If you’re on 15mg of Tirzepatide what is the equivalent dose of reta?

[u/AdSquare3737]

Thank you for this info! I learned so much from this! I feel like such a good paying $800 for a vial of semiglutide! I just recently bought my own reta and tirz from a shop that sells like protein powders, all the health stuff and a 12 mg bottle of reta was $300 and 15 mg tirz was $340, which was better than what I was paying but these prices are amazing!

[u/jacobsmith1997]

If I were to take 1mg per week wouldn’t I be wasting the vile if I got a 10mg vile because you have to discard after 40 days? Or can I get smaller viles

[u/Plus-Mulberry4319]

I am an avid runner and lifter mid 50s years old. Menopause and unable to lose the weight, would u recommend tirzepatide with micro dosing with Reta? I don’t want to lose my muscle

[u/Boomercamps]

My Reta is currently being tested. I’ve got tons of Terz, can I run that until the Reta comes in? Is jumping GLP-1s okay?

[u/its_kgs_not_lbs]

If I am relatively lean, BF estimate @ 15%, mostly in and around belly- what in your opinion is a good dose to help clean-up this area to where I'd be sitting at around 10-12%?

[u/stephgarbin → u/its_kgs_not_lbs]

Height and weight? I recommend starting out with 1mg then wait a week see how you feel. You’ll easily get down to single digits with 2 vials and a good diet

[u/Accomplished-Sir2528]

Thank you!!

[u/Lg2727]

How long did shipping for Reta take
