Levonorgestrel cyclopropylcarboxylate (developmental code name HRP-003), or levonorgestrel 17β-cyclopropylcarboxylate, is a progestin and a progestogen ester which was studied for potential use as an injectable hormonal contraceptive but was never marketed.[1][2][3][4][5][6][7][8][9][10] It was developed by the World Health Organization's Special Programme on Human Reproduction in the 1980s.[1][2][9] Analogues of levonorgestrel cyclopropylcarboxylate include levonorgestrel cyclobutylcarboxylate (HRP-001) and levonorgestrel butanoate (HRP-002).[1][2][3]
