Buserelin
Buserelin is a potent GnRH agonist: after an initial stimulatory surge ('flare'), continuous receptor occupancy causes downregulation and thereby suppression of LH, FSH and the downstream sex hormones.
Teriparatid
Teriparatide corresponds to the biologically active first 34 amino acids of human parathyroid hormone and binds the PTH-1 receptor on bone and kidney cells. The literature describes that intermittent receptor activation preferentially stimulates the activity of bone-forming osteoblasts, whereas continuously elevated PTH exposure (as in hyperparathyroidism) tends to favor bone resorption. This time-dependent difference is regarded as the mechanistic basis for the bone-anabolic effect observed in studies.

Frequently asked questions
- What is the difference between Buserelin and Teriparatid?
- Buserelin is classified as "Research other", while Teriparatid is classified as "Research other". Buserelin: Buserelin is a synthetic GnRH agonist (including as a nasal spray). It is used in endometriosis, hormone-dependent prostate cancer and assisted reproduction; approved in Europe (Suprefact), not in the US. Teriparatid: Teriparatide is the recombinant N-terminal fragment 1-34 of human parathyroid hormone (PTH). It is regulatory-approved and studied in the scientific literature as a bone-anabolic agent for the treatment of osteoporosis. Unlike antiresorptive agents, studies attribute to it an effect that stimulates new bone formation. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Buserelin or Teriparatid?
- The highest available evidence level is "Human RCT" for Buserelin and "Human RCT" for Teriparatid. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Buserelin and Teriparatid in Germany and the United States?
- Germany: Buserelin — Prescription, Teriparatid — Prescription. United States: Buserelin — Unapproved, Teriparatid — Prescription. These are factual summaries with source and review date on the individual pages.
