parabolan

Parabolan is the brand name for trenbolone hexahydrobenzylcarbonate, a veterinary injectable anabolic-androgenic steroid. It is a long-acting ester of trenbolone, a potent synthetic androgen. The hexahydrobenzylcarbonate ester slows the release of trenbolone after intramuscular injection, producing prolonged biological effects for several weeks.

In veterinary medicine, Parabolan is used to promote growth, improve feed efficiency, and influence carcass composition in cattle. It is administered under veterinary supervision and regulatory guidelines, often as part of implant systems or injections designed for livestock production. Its use in humans is not approved in most countries and it is typically classified as a controlled substance because of its potential for abuse.

Safety, regulation, and legality vary by jurisdiction. In humans, Parabolan is not approved for medical treatment and illicit use is associated with legal penalties and health risks. In addition to potential androgenic effects, users may experience acne, oily skin, hair loss in those predisposed, voice changes, and virilization in women. There is also concern about metabolic and lipid disturbances and possible cardiovascular effects. In livestock production, withdrawal times and meat residue limits regulate its use to ensure safety for consumers.

Because Parabolan is not approved for human therapy, information on dosing and therapeutic indications is limited to veterinary contexts and regulatory documents. Unauthorized or non-regulated use carries significant legal and health risks and is monitored by anti-doping and veterinary authorities.
