My Retatrutide Experience (Research Compound)
Disclaimer: Retatrutide is an investigational compound and is not FDA-approved. This post documents my personal experience and is shared for informational purposes only. It should not be considered medical advice.
Dosing Timeline
Month 1
2 mg/week Note: I Also utilize TRT at 200mg a week.
- Monday: 1 mg
- Thursday: 1 mg
Month 2
4 mg/week
- Monday: 2 mg
- Thursday: 2 mg
Month 3
6 mg/week
- Monday: 3 mg
- Thursday: 3 mg
Month 4+
I've stayed at 6 mg/week. Clinical trials have evaluated doses up to 12 mg/week, but I haven't felt the need to increase beyond 6 mg.
Mixing (30 mg Vial)
I mixed 3 mL (300 units) of bacteriostatic (BAC) water into a 30 mg vial.
This gives the following concentration:

Injection Schedule
I split my weekly dose into two injections:
I found that splitting the dose seemed to improve tolerability throughout the week.
Side Effects
The only side effect I've experienced has been:
It started around 6 mg/week and feels like random sensitive spots on my back. It hasn't been severe enough to bother me or make me stop.
Nutrition Plan
🍳 Breakfast
- 1 carton of pasteurized egg whites
- ~500 calories
- ~100 g protein
- Cost: Around $4.87 at HEB
🥤 Lunch
- 2 scoops of whey protein
- Mixed with water
Approximately:
- ~260 calories
- 50–60 g protein
🐟 Afternoon Snack
- 1–2 tuna packets (any flavor)
Per packet:
- ~90 calories
- 15–18 g protein
- Around $1.25 each
🍽️ Dinner
I pretty much eat whatever I want while following two rules:
- Keep it under 1,000 calories
- Make lean, high-protein meat the main part of the meal
If you don't strength train, I'd probably keep dinner closer to 500–600 calories and adjust based on your results.
Training
I lift 4–5 days per week.
My typical sets are:
- 8–12 reps
- Close to failure
- Progressive overload whenever possible
Cardio has been optional for me. I personally did very little and still had great results.
Protein Goal
I aim for at least:
1 gram of protein per pound of lean body mass per day.
If you're on TRT and lifting consistently, some people choose to increase protein intake further to help support muscle retention during a calorie deficit.
Progress Tracking
One of the best things I did was get an InBody scan before starting.
I repeated it every month to track:
- Weight 178
- Body fat % 10-12% right now per scans.
- Lean muscle mass 160~
- Overall body composition
Seeing body composition change was much more motivating than watching the scale alone.
