The honest answer is that it depends on your goals, and in many cases the most effective approach combines both. PRP is ideal when there is a specific area of injury or inflammation, such as a knee, shoulder, or hip, because it delivers a concentrated dose of your own growth factors directly to that site. Peptide therapy works more systemically, supporting recovery, hormone balance, and cellular repair throughout the entire body. At Relive Health Brentwood, we use your blood work results to determine which approach, or which combination, is the right fit for where you are and what you are trying to achieve.
