At MD Total Wellness in Orange County, we specialize in medically supervised peptide therapy to optimize wellness and vitality. Sermorelin and tesamorelin are two popular GHRH (growth hormone-releasing hormone) analogs that stimulate your body’s natural production of growth hormone (GH) to combat age-related decline. Both offer benefits for body composition, energy, and recovery, but they differ in how they are used —sermorelin is typically used for broad anti-aging and wellness effects (due to being more researched for these outcomes), while tesamorelin is typically used to specifically target visceral fat reduction (because this is what most tesamorelin studies focused on).
If you’re experiencing low energy, muscle loss, increased abdominal fat, or diminished sleep quality, one of these peptides may help restore your vitality. We offer medical guidance, quality medication, and personalized plans for optimal results. Schedule a free consultation today to discuss which option is right for you.
Sermorelin is a 29-amino acid peptide that closely mimics natural GHRH, promoting pulsatile GH release aligned with the body’s natural rhythms. Discovered in the 1980s and FDA-approved in 1997 for pediatric GH deficiency, it’s now used off-label for adult wellness.
Tesamorelin is a 44-amino acid modified GHRH analog that provides more potent and sustained GH stimulation than sermorelin. FDA-approved in 2010 for reducing visceral fat in HIV-associated lipodystrophy, it’s now commonly used off-label for wellness when a particular focus is metabolic health and visceral fat reduction.
At MD Total Wellness, both peptides are manufactured in the USA, >99% pure, 3rd party tested, and free of hidden ingredients. Both peptides are administered via subcutaneous injections for at-home convenience. Sermorelin’s shorter half-life (6-11 minutes) suits general anti-aging, while tesamorelin’s longer half-life and higher potency (11-38 minutes) excels in metabolic targeting.
Both peptides restore declining GH levels (which drop 14% per decade after age 30) to enhance vitality, but their strengths differ:
Sermorelin improves lean muscle, reduces overall fat, and boosts metabolism; tesamorelin specifically reduces visceral (abdominal) fat by 15-20% in studies, with benefits for liver fat and cardiometabolic health.
Sermorelin increases stamina and daily energy by enhancing natural GH pulses and rhythm; tesamorelin may have similar effects but it has been less studied for general vitality.
Sermorelin, dosed at bedtime, enhances deep sleep; tesamorelin’s effects on sleep are less studied.
Sermorelin promotes skin thickness, bone density, mood, and cognition; tesamorelin may have similar effects, but has been less studied for promoting skin, bone, and cognitive health.
Both aid muscle repair and reduce inflammation, with sermorelin having the larger body of research documenting effectiveness.
Patients often notice energy and sleep improvements in 1-4 weeks, body composition changes in 1-3 months, and full benefits in 3-6 months.
Both bind to pituitary GHRH receptors to stimulate natural GH release and elevate IGF-1 (insulin-like growth factor-1), which mediates GH’s effects on metabolism, repair, and rejuvenation.
Sermorelin promotes physiological, pulsatile GH patterns that preserve the hypothalamic-pituitary axis and align with natural rhythms (e.g., nighttime surges). Tesamorelin stimulates more sustained GH elevation, ideal for lipolysis for visceral fat reduction and metabolic improvement. We monitor IGF-1 levels to ensure safe, effective dosing.
While direct comparisons are limited, sermorelin’s shorter action may better suit wellness optimization, whereas tesamorelin’s sustained stiulation targets specific metabolic concerns.
Decades of research support GHRH analogs for GH restoration. Sermorelin studies in aging adults show restored GH/IGF-1 levels, improved muscle strength, skin health, and quality of life, with a strong safety profile in trials. For example, a 1997 study linked it to enhanced immune function and vitality. Tesamorelin has robust data from FDA trials, demonstrating 15-20% visceral fat reduction over 6 months in HIV patients, with benefits for lipids and insulin sensitivity. While tesamorelin’s research is niche-focused, sermorelin offers broader evidence for addressing age-related decline in healthy adults. Both preserve natural GH feedback better than direct GH injections, minimizing risks.

Tesamorelin may be appropriate for:
At our Brea office, we provide medical guidance, follow-up, and monitoring. We’ll dispense medication from the office or ship to your door and teach you how to do injections. Protocols are personalized with follow-up and IGF-1 monitoring:
Sermorelin: 0.2-0.5 mg nightly before bed; weekly cycles (5d/wk).
Tesamorelin: 1-2 mg nightly before bed; weekly (5d/wk) and monthly (3mo on, 1 mo off) cycles.
Price: $250 per 10mg vial for sermorelin (1-2 month supply); $300 per 20mg vial for tesamorelin (1 month supply).
We track progress monthly for safety and adjustments. Results typically emerge in weeks for energy/sleep and 1-3 months for body composition.
Sermorelin and tesamorelin have strong safety profiles, when used under supervision, with benefits outweighing risks in appropriate candidates. Mild side effects may include injection-site reactions, flushing, headache, or transient glucose changes (more common with tesamorelin). Contraindications include active cancer and uncontrolled diabetes.
