What Sermorelin Is
Sermorelin is a growth-hormone-releasing hormone analog that prompts your own pituitary to release growth hormone. It is taken as a nightly subcutaneous injection, and most people notice it in sleep in 2 weeks; composition in 2 to 3 months.
What Tesamorelin Is
Tesamorelin is a GHRH analog with specific data on abdominal fat; an FDA-approved version exists for one HIV-related use. It is taken as a nightly subcutaneous injection; needs IGF-1 labs, and most people notice it in 2 to 3 months.
