- Sermorelin (GRF 1-29) had FDA approval from 1997 to 2008 under the brand name Geref, indicated for diagnosing GH deficiency in children. EMD Serono voluntarily withdrew it in 2008 for commercial reasons, not safety concerns.
- Sermorelin is still available through compounding pharmacies but has no active FDA approval. Its clinical safety record is strong (decades of human use data, multiple controlled trials), but the evidence base is smaller than tesamorelin's for fat reduction.
