For patients who want to address several aspects of age-related decline at once, combining sermorelin and NAD+ therapy, sometimes called a sermorelin NAD stack, has become more popular. But does using both therapies together make sense, and what should you know before trying this approach? Here's a practical look.

Why Combining Sermorelin and NAD+ Makes Biological Sense

Sermorelin and NAD+ work on different but related systems in the body. Sermorelin helps the pituitary gland make more growth hormone, which supports body composition, sleep, recovery, and tissue repair. NAD+ helps with cellular energy, DNA repair, sirtuin activation, and mitochondrial function. Each therapy has its own role, but together they can address more aspects of age-related decline.

Here's another way to look at it: sermorelin improves your hormone signals, and NAD+ helps the cells respond to those signals. Growth hormone tells your cells to repair and build, while NAD+ gives them the energy and support they need to do the job. When both systems work well, the results can be better than using either therapy alone.

Potential Benefits of Combined Therapy

Patients who use both sermorelin and NAD+ together often notice more improvement than with just one therapy. Many report having more energy and feeling less tired when both are combined. Sleep quality may also improve, since sermorelin helps with deep sleep through growth hormone, and NAD+ supports the body's natural sleep-wake cycle through sirtuins. Hormone optimization is paired with adequate NAD+-mediated metabolic support. Recovery from exercise and physical stress tends to benefit from both GH-mediated tissue repair and NAD+-driven cellular energy restoration. Some patients report improvements in cognitive function that they attribute to the combination rather than either therapy individually.

Practical Considerations

Using two therapies at the same time takes more careful planning than just one. Your provider will need to manage the doses for both, check more lab results, and watch for any interactions or combined effects. The injection schedule is also more involved. Sermorelin is usually given before bed, while NAD+ injections may be scheduled at another time.

Cost is another thing to consider. Using both therapies means paying for both, so it's important to understand the total cost and have realistic health goals before starting.

Who Is a Good Candidate for Stacking?

A sermorelin NAD stack is usually best for patients who have low levels of both growth hormone and NAD+, have health goals that involve both hormones and cells, can commit to regular monitoring and follow-up, and already have healthy lifestyle habits in place.

Stacking both therapies is not always the best first step. Some patients do better by starting with one therapy, seeing how they respond, and then adding the second after getting a clear baseline. Your provider can help you decide the best order. However, combining any therapies means tracking more variables. Regular lab work becomes even more important, and clear communication with your provider about how you're feeling is essential. If side effects emerge, your provider needs to determine which therapy is the likely contributor and adjust accordingly.

At HRT Wellness, we provide both sermorelin and NAD+ therapy and have experience creating combined plans that fit each patient's goals. Contact us to see if a stacked approach is right for you.
