Tesamorelin vs Sermorelin
Tesamorelin vs Sermorelin: two GHRH analogs head-to-head on potency, FDA status, cost, and dosing protocol.
The verdict
Same mechanism (both are GHRH analogs), different weight class. Tesamorelin is the more potent, FDA-approved one with real data behind visceral-fat reduction, and it costs more. Sermorelin is the older, gentler, cheaper sibling, lighter touch on the GH axis. If you specifically want stronger effect and visceral-fat targeting, Tesamorelin. If you want an easy, low-cost entry into GHRH-style support, Sermorelin does the job with less intensity.
Tesamorelin is an FDA-approved GH-axis peptide that specifically targets visceral fat, the deep belly fat around organs. Daily injection. Slow burn, but the visceral fat reduction is well-documented.
Sermorelin is the older, gentler cousin in the GH-axis family. Approved decades ago. Often used by anti-aging clinics for adults with declining GH output. Daily injection at bedtime.
Which one should you pick?
Pick Tesamorelin if users targeting visceral (deep abdominal) fat specifically or older adults wanting gh-axis support without hgh.
Pick Sermorelin if beginners to gh-axis peptides or older adults with declining gh output.

Common questions
- Can you stack Tesamorelin with Sermorelin?
- Neither entry lists the other as a stack partner. Each full entry has its own stacking notes.
- What's the dose difference between Tesamorelin and Sermorelin?
- Tesamorelin: 1-2 mg sub-q daily. Taken at the same time each day, ideally before bed.
- Sermorelin: 200-500 mcg sub-q nightly, on an empty stomach. Some protocols use 100-300 mcg twice daily.
- Is Tesamorelin or Sermorelin FDA approved?
- Tesamorelin: Approved as Egrifta, 2010, for HIV-associated lipodystrophy.
- Sermorelin: Approved as Geref (1997) for treatment of pediatric growth hormone deficiency. Discontinued by the manufacturer around 2008 for commercial reasons (the FDA's 2013 determination explicitly states it was not withdrawn for safety or effectiveness). Now compounded-only, not FDA-approved as a finished product.
- What are the side effects of Tesamorelin vs Sermorelin?
- Tesamorelin: Injection-site reaction; Fluid retention; Joint stiffness.
- Sermorelin: Head-rush at injection; Hunger pulse 30-60 min post-dose; Mild flushing.
