Longevity

Starting in your mid-20s, your body makes less of the compounds that keep you feeling sharp, like NAD+, growth hormone, and collagen. That decline shows up as brain fog, slower recovery, and energy that doesn't bounce back. Longevity treatment, including NAD+ therapy and anti-aging peptides, works by replenishing those systems directly, so your body has what it needs to repair and perform. This isn't about chasing more years on the calendar. It's about staying sharp, energized, and fully present for the life you already have.

Sermorelin, GHK-Cu, and PT-141 are peptides, short chains of amino acids that act as precise signals for one system in your body. That precision is part of why peptides have become a go-to tool in the biohacking and longevity world, favored over broader-acting compounds. NAD+ is the outlier of the group, a coenzyme rather than a peptide. Glutathione is technically a tripeptide too, but it's grouped here for what it does, a powerful antioxidant, rather than as a hormone-signaling peptide like the other three.

NAD+ is the coenzyme every cell runs on for energy, DNA repair, and staying sharp, and your natural levels decline as you age. Replenishing it, by injection, oral tablet, or nasal spray, is one of the most direct ways to support energy, focus, and cellular resilience from the inside out.

Sermorelin is a peptide that works with your pituitary gland to encourage your body to release more of its own growth hormone, rather than introducing synthetic growth hormone directly. As natural levels decline with age, Sermorelin helps support recovery, sleep quality, and energy through a busy, full life. It's one of the longer-studied peptides in this space: the FDA confirmed in a 2013 Federal Register notice that the original sermorelin acetate product was discontinued for commercial reasons, not safety or effectiveness.

Glutathione is your body's master antioxidant, working behind the scenes to protect your cells, support liver detoxification, and help you bounce back faster from everyday stress. Levels decline naturally with age, and replenishing it supports both how you feel and how your skin looks.

GHK-Cu is a copper-binding peptide your body already produces, just less of as you age. It plays a direct role in skin repair and collagen production, restoring firmness and resilience from the inside rather than just on the surface. Its role in tissue repair has been studied for decades, including research indexed in the National Library of Medicine's PubMed database.

PT-141 works centrally, in the brain rather than the body, to support sexual desire and arousal for both men and women. It addresses intimacy at the source, not just the physical response.
