Da****L.
Pairing this with my gym routine, body fat has been dropping way faster than before. Appetite stays steady all day.
Em****G.
Appetite control is unbeatable with the 40mg. Only wish the pen cap was a little sturdier for travel — super minor issue, will definitely reorder.
Ry****.
On 40mg for 2 months, down 18 lbs with light walking. Controls my overeating at work lunches completely. Already ordered my next pen.
Li****.
Tried 3 other brands before, this 40mg Retatrutide is by far the most consistent. Quality feels premium, COA included, no weird side effects.
Da****R.
40mg is seriously effective for controlling hunger. Had very mild nausea the first 2 days, totally bearable and went away fast. 100% worth it.
Sa****L.
Moved up from 20mg to 40mg after building tolerance. My sugar cravings are completely gone, weight loss stays consistent even on vacation.
