✨ What exactly is Tirzepatide and Retatrutide?
Weekly subcutaneous products that strongly reduce appetite and accelerate fat loss. Tirzepatide = steady, proven results. Retatrutide = stronger next‑gen option for faster fat loss with lean mass preserved — a favourite among gym users.
📊 Which is stronger?
Retatrutide is stronger than Tirzepatide, especially for users training in the gym who want aggressive fat loss with strength maintained.
📍 Where do I inject?
Subcutaneous (under the skin) into the stomach, thigh, or upper arm. Rotate sites each week for comfort.
🗓️ How often?
Once weekly, same day each week.
🖊️ Pen vs Vial — what’s the difference?
Pen: ready to inject, dial and go (maximum convenience). Vial: lower price and flexible dosing for experienced users.
📏 How do I measure a vial dose?
We include simple, step‑by‑step guidance. Message us 24/7 and we’ll walk you through your exact setup.
🥶 Storage & handling
Keep refrigerated at 2–8°C. Do not freeze. Travel with a cool pack.
⏳ When do results show?
Appetite changes often within week 1; visible fat loss commonly in 2–4 weeks.
📈 How much weight can I lose?
Tirzepatide supports significant, steady loss; Retatrutide is chosen for more aggressive cuts with better muscle preservation.
😊 Positive effects
Strong appetite control, easier portion sizes, smooth energy, and steady fat loss. Gym users love Retatrutide for “cutting while staying strong.”
⚠️ Possible side effects
Some users notice mild nausea, digestive changes, or small bruising at the injection site — usually easing as the body adapts.
🍽️🏋️ Do I need diet or exercise?
Not required, but healthy eating and training amplify results. Retatrutide is our top pick for gym‑goers targeting fat loss with strength maintained.
🍷 Can I drink alcohol or eat carbs?
Yes. Keep alcohol moderate for best progress; no foods are “banned” — smaller portions work best.
💊 Can I combine with other supplements or meds?
Usually fine. If you’re unsure about a specific combo, message us and we’ll advise 1‑to‑1.
