As interest in hormone optimization and longevity medicine grows, many people are turning to sermorelin to restore energy, improve sleep, and support natural growth hormone production. But if you’re already following a wellness regimen, or considering adding testosterone therapy, NAD+, or vitamins, you need to be careful about how you combine them with sermorelin.
The truth is, some combinations can create powerful synergy, while others can interfere with your body’s natural hormone rhythms. Doing it right requires understanding how each wellness therapy works and how to stack them safely.
At Genesis Lifestyle Medicine, our multidisciplinary team takes a science-based approach to designing combination protocols that enhance the results of your sermorelin therapy while keeping your health and hormones in perfect balance. In this article, we describe what you should and shouldn’t do when combining sermorelin with other treatments.
DOs of mixing sermorelin with other therapies
DO combine sermorelin with testosterone therapy
If you’ve been diagnosed with low testosterone, combining sermorelin with testosterone therapy (TRT) can produce complementary benefits. While sermorelin stimulates your pituitary gland to release natural growth hormone, testosterone helps increase muscle mass, libido, and mood stability. Together, they can improve energy, recovery, and overall body composition.
However, this combination requires careful monitoring. Growth hormone and testosterone both influence metabolism, insulin sensitivity, and red blood cell production. Our providers routinely test hormone panels and adjust dosing to maintain optimal balance, never excess. When managed properly, this combination can help you feel revitalized from the inside out.
DO pair sermorelin with NAD+ therapy
Nicotinamide adenine dinucleotide (NAD+) plays a central role in mitochondrial function and energy metabolism. Over time, NAD+ levels decline, contributing to fatigue, slower recovery, and cognitive fog. Sermorelin works at the hormonal level, while NAD+ supports energy at the cellular level. When used together, they can enhance your ability to repair and regenerate.
This may be especially beneficial for individuals focused on longevity, athletic performance, or recovery from burnout. By promoting cellular energy and optimizing growth hormone signaling, NAD+ and sermorelin can improve clarity, stamina, and vitality. At Genesis Lifestyle Medicine, both treatments are personalized to your metabolism and goals for maximum safety.
DO add vitamin B12 for metabolic support
Vitamin B12 is essential for red blood cell formation, nerve health, and energy production. Many adults, especially those with certain diets or absorption issues, have suboptimal B12 levels, which can cause fatigue, brain fog, or low mood. Supplementing with B12 injections while on sermorelin therapy can support your energy levels, metabolism, and overall wellness.
Because sermorelin enhances your natural growth and repair processes, maintaining adequate nutrient support is key. Vitamin B12 works synergistically to optimize these effects by improving oxygen transport and energy utilization. The result? Better endurance, sharper focus, and a more sustained sense of well-being.
DO engage in exercise and healthy fasting practices
No peptide protocol can replace lifestyle habits that naturally boost growth hormone. Resistance training, high-intensity exercise, and intermittent fasting are proven ways to stimulate natural GH release and fat metabolism. When combined with sermorelin therapy, these habits reinforce your body’s natural rhythms and accelerate results.
Exercise increases muscle sensitivity to GH, while fasting reduces insulin spikes that can suppress GH secretion. Together, they strengthen sermorelin’s physiological effects. Genesis Lifestyle Medicine providers often recommend tailored nutrition and fitness plans to ensure you get the most from your treatment program.
DON’Ts of mixing sermorelin with other therapies
DON’T self-prescribe or stack multiple hormones without testing
Combining peptides, testosterone, thyroid medication, or other hormones without supervision can throw your body out of balance. Hormones work through intricate feedback loops: if you add too many variables, you can disrupt natural production or overstimulate certain pathways.
Without proper testing, you risk side effects such as water retention, elevated blood sugar, or suppressed pituitary function. Our clinicians always perform comprehensive hormone panels before starting or modifying any therapy. Skipping that step could mean compromising your long-term health for short-term gains.
DON’T use unregulated or over-the-counter peptide products
Not all sermorelin products are created equal. Unregulated or internet-sourced peptides may contain impurities, incorrect dosing, or even counterfeit ingredients. Combining low-quality compounds with other therapies can cause unpredictable reactions or infections.
Always use prescription-grade peptides from licensed compounding pharmacies. Genesis Lifestyle Medicine only partners with FDA-registered pharmacies that meet strict safety and purity standards, ensuring you receive authentic, effective products.
DON’T mix sermorelin with stimulants or performance enhancers
Caffeine, fat burners, and pre-workout stimulants can over-stress your nervous system, increase blood pressure, and interfere with natural hormone signaling. When combined with sermorelin, they may blunt benefits or increase side effects like insomnia or palpitations.
If you rely on caffeine or energy boosters, discuss this with your provider. Often, once sermorelin restores your natural energy production, you’ll find less need for stimulants altogether. Balancing your internal chemistry naturally is safer and more sustainable.
DON’T expect identical results from others’ protocols
You might read about someone achieving dramatic results with a certain peptide stack, but your biology, goals, and lifestyle are unique. What worked for someone else might not be right for you. Copying another person’s protocol can lead to imbalances or side effects.
Genesis Lifestyle Medicine emphasizes individualized treatment, based on your biomarkers, metabolism, and health history. Your medical provider will design a combination that enhances your specific physiology, not a generic plan found online.
When used strategically, sermorelin can work synergistically with other wellness therapies to restore vitality, enhance recovery, and support graceful aging. However, not every combination is safe, and overdoing it can disrupt your body’s delicate hormone balance.
At Genesis Lifestyle Medicine, our team of medical professionals customizes every peptide and hormone protocol with comprehensive testing and ongoing supervision. The goal is simple: to help you heal, perform, and thrive from the inside out, safely and effectively.
