What is the difference between Sermorelin and Tesamorelin?

The main difference is mechanism and research stage. Sermorelin targets GHRH receptor (GHRHR) (research-use-only (former geref diagnostic)) and is studied for pituitary GH-secretion research; Tesamorelin targets GHRH analog (approved formulations exist) and is studied for visceral/hepatic fat research. Both are research-use-only compounds, not for human or animal use.

Are Sermorelin and Tesamorelin approved for human use?

No. Renova Wellness supplies both strictly for in-vitro laboratory and scientific research use only. Research status differs — Sermorelin: research-use-only (former geref diagnostic); Tesamorelin: approved formulations exist — but neither is sold for human or animal consumption, and no medical, therapeutic, or dosing claims are made.

How is purity verified for Sermorelin and Tesamorelin?

Every lot of both compounds ships with its own per-batch Certificate of Analysis — identity by mass spectrometry, ≥98% purity by HPLC, and a unique lot number you can verify against the vial in your hand.

Research Comparison

Sermorelin vs Tesamorelin

Sermorelin and Tesamorelin are often compared because both sit in growth-hormone axis research. Sermorelin acts on GHRH receptor (GHRHR) and is studied for pituitary GH-secretion research, while Tesamorelin acts on GHRH analog and is studied for visceral/hepatic fat research. Both are supplied as lyophilized powder for in-vitro laboratory research only — this page compares mechanism and research status, not dosing or human use.
