Retatrutide summary

The weight loss journey using retatrutide, which began on September 19, 2025, at a weight of 199.3 lbs, successfully led to a final recorded weight of 174.9 lbs on Jan 1, 2026, achieving the goal of reaching 175 lbs. Initial doses, which ranged from 0.8 mg up to 3.3 mg, were highly effective, producing a strong sense of fullness, a significant decrease in appetite (often referred to as "food noise"), and a reduced desire for sweet things, making habitual snacks feel unappetizing or like a chore. However, the primary challenge and most relevant side effect was a recurring, repeatable histamine-like skin reaction, characterized by a mild red, itchy spot at the injection site, which the user attempted to mitigate by varying injection sites (quadriceps, stomach, inner thigh, butt cheek) and modifying injection speed and temperature. The strong initial effects diminished over time, suggesting the body was developing a tolerance and leading to an increase in dosing and an occasional need to overcome the lack of hunger to ensure proper nutrition for workouts. Despite the benefits, the user noted that compliance with the detailed preparation and injection protocol was difficult, resulting in several unintentional deviations and mistakes, such as drawing incorrect liquid volumes or accidentally using a mixing needle for injection
