Following peptide therapy, you will begin seeing results in as little as a couple of months; however, full benefits are noticed after approximately four to six months. After the six-month mark, you can expect to see a 5-10% reduction in body fat without changing your diet or exercising. However, it is important to note that working out and eating healthy in combination with peptide therapy will help you improve your overall health and achieve the best, most long-lasting results.
