Nevolat weight loss injection pens (Generic Saxenda) contain the active ingredient liraglutide - a licensed GLP-1 weight-loss treatment. Saxenda itself has been discontinued and has now been replaced with a branded-generic called Nevolat. Initiation with Liraglutide is 1 month, or 3 PENS as it takes around a month to see any noticeable benefit. Taking Nevolat daily makes you feel less hungry, slows down the movement of food out of the stomach and makes you feel fuller for longer. The effect is a reduced calorie intake, making you, the patient, lose weight.
