1-Testosterone (abbreviated and nicknamed as 1-Testo, 1-T), also known as δ¹-dihydrotestosterone (δ¹-DHT), as well as dihydroboldenone, is a synthetic anabolic–androgenic steroid (AAS) and a 5α-reduced derivative of boldenone (Δ1-testosterone). It differs from testosterone by having a 1(2)-double bond instead of a 4(5)-double bond in its A ring.^[1] It was legally sold online in the United States until 2005, when it was reclassified as a Schedule III drug.
