Growth hormone treatment had finally become possible.
But there was a remarkable limitation.
Every dose of human growth hormone depended on pituitary glands collected after death.
The treatment could help children with severe GH deficiency grow—but the supply was scarce.
Then another field of science began changing what was possible.
Scientists learned to use genetic instructions to produce human proteins.
By 1979, recombinant human growth hormone had been produced.
And then came 1985.
Young adults who had received pituitary-derived GH years earlier developed Creutzfeldt-Jakob disease.
The old source was withdrawn.
But another source was already approaching clinical use.
In October 1985, the FDA approved Protropin, a recombinant growth hormone product.
A scarce human extract was becoming a manufactured medicine.
Growth hormone had entered a new era.

With recombinant GH now available, scientists could investigate the hormone in ways that had never been possible before.
