Tesamorelin vs sermorelin — what is the difference?
Both are GHRH analogs, but tesamorelin carries a hexenoyl modification that resists enzymatic breakdown, so it stays intact far longer than sermorelin.
Why pair tesamorelin with ipamorelin?
Tesamorelin acts on the GHRH receptor while ipamorelin acts on the ghrelin/GHS receptor — two separate pathways studied together for additive signaling.
Is a certificate of analysis provided with tesamorelin?
Yes. Every tesamorelin lot has a published, lot-matched COA showing HPLC purity and LC-MS identity confirmation.
How should tesamorelin be stored?
Store the lyophilized vial at -20°C protected from light. Once reconstituted with bacteriostatic water, keep it refrigerated at 2–8°C.
