Calcitonin vs Teriparatide
Two bone-directed hormones going opposite ways: the antiresorptive that slows bone loss vs the anabolic that builds it. Here's a neutral, sourced side-by-side — no hype, every claim links to its evidence.
Calcitonin
ApprovedAlso: Calcitonin, rat
Calcitonin is a natural hormone made in the body, specifically by a gland in the neck called the thyroid. It is classified as a peptide hormone, which means it is a small protein that acts like a signal in the body.
Teriparatide
ApprovedAlso: Teriparatide plus zoledronic acid sequential treatment, Teriparatide followed by Zoledronic Acid (TOPaZ Trial Protocol)
Teriparatide is a man-made medicine that acts like a specific hormone your body makes to build bone. It is used by people with weak bones, a condition known as osteoporosis, to help make their bones stronger and prevent breaks.

Decision Guide
How to Choose
Neither is a “winner” — they suit different goals. Compare the documented benefits and evidence above against what you’re actually trying to achieve, note the research status (approved vs research-stage), and read each full guide before deciding. Many people also stack peptides rather than pick one.
