You can expect both short and long-term benefits from peptide therapy. In the days immediately after treatment, many patients report increased energy, improved sleep quality, reduced joint pain, and faster injury healing. With continued therapy spanning weeks to months, patients may achieve muscle gain, fat loss, tighter skin, stronger joints, enhanced libido, improved mood, and an overall younger appearance and physiology. Results depend on the peptides used, lifestyle factors, diet, and the patient's unique biology.
