Retatrutide
The strongest fat-loss compound there is — and the only one that actively burns stored fat. It melts fat (especially the dangerous fat around your organs) while holding onto muscle far better than Ozempic or Mounjaro.
📊 The Protocol
Vial20 mg
Mix with2 mL BAC water → makes 1 mg = 10 units
Start10 units (1 mg) — once a week
Go up by+5 units (0.5 mg) every 1–2 weeks — only if needed
Sweet spot20–40 units (2–4 mg)
Ceiling150 units (15 mg) — a limit, NOT a goal
WhenPM, fasted (empty stomach), under the skin
🧮 Units made simple: your insulin syringe is marked 0–100. That whole line = 1 mL. Just draw to the 10 mark — that's your dose. Going up? Draw to 15, then 20. No math.
⏳ How long one bottle lasts
At 1 mg 10u~20 weeks (nearly 5 months)
At 2 mg 20u~10 weeks
At 4 mg 40u~5 weeks
One 20 mg vial = 200 units total. Reta is dosed once a week, so a bottle lasts a long time — that's part of why it's such good value.
💉 How to take it
Mix: add the 2 mL of BAC water slowly down the side. Swirl gently — never shake.
Store: in the fridge after mixing. Good for ~4–8 weeks.
Inject: into belly fat, ~2 inches from your navel. Pinch, go straight in, push slow. Rotate the spot each week, fresh pin every time.
🍽️ Your diet — this one's not optional
Eat45–55% of calories from slow carbs (rice, potatoes, oats).
Neverketo or fasted — without carbs the glucagon arm eats your own muscle.
Protein1–1.5 g per lb of goal bodyweight (protects muscle).
💊 Take these alongside it
Liver supportIt works your liver hard: TUDCA + NAC + magnesium glycinate + zinc.
Muscle + baseCreatine 5–10 g, Vitamin D3, B12.
Prime firstRun MOTS-c 4–6 weeks before, so your body can handle the fat release.
⚠️ Watch for / red flags
Nausea = dose too high. Go DOWN — don't push through it.
Losing muscle? Add leucine + collagen, lift weights, cap fat loss at ~1%/week.
Get labs: GGT, ALT, lipase. Lipase over 3× normal = STOP.
🚨 Stop & see a doctor if you get upper-belly pain that spreads to your back, pale stools, or yellow skin/eyes.
🚫 Who should NOT take it
You or a blood relative has had medullary thyroid cancer or MEN2
You've ever had pancreatitis
Pregnant, breastfeeding, or trying to conceive
Active gallbladder disease
Type 1 diabetes — only with a doctor's supervision
🔬 How it works
It's a triple agonist — it pulls three levers at once. GLP-1 kills your appetite. GIP browns your fat and raises how much energy you burn by 10–15%. And the glucagon arm forces your liver to burn stored fat — that "gas pedal" is what no other GLP-1 has.
💡 Pro Tips
The dose trap: 4 mg → 8 mg is "a 5% increase in fat loss and a 300% increase in side effects." Above 4 mg the receptors are full — more is just organ damage.
It NEEDS carbs — running it keto sabotages it. Without carbs your body eats your muscle for fuel.
"It stopped working" = you didn't titrate, not tolerance. But if you can't finish meals, taper DOWN.
NEVER stack with Tirzepatide or Semaglutide — same receptor, so you can't double it, you just double the organ damage. To break a plateau, add Tesamorelin.
