Boldenone undecylenate
Anabolic steroidsAlso known as Equipoise, EQ
A long-acting veterinary androgen, originally for horses.
How it works
Structurally testosterone with an extra double bond, which slows aromatisation without stopping it. Mild androgenically relative to its anabolic effect.
In the body
No plasma curve is shown for this compound.
No human pharmacokinetic study exists. The undecylenate ester is long, a close relative of the undecanoate on injectable testosterone, which empties over weeks, so a similar order is likely, but likely is not measured.
Doses
Community convention. No human clinical dosing exists.

Side effects
- A pronounced rise in haematocrit, reported more consistently than for most compounds here
- Increased appetite
- Aromatises, so oestradiol-driven effects apply
- Very long detection window in anti-doping tests
- Monitor: Haematocrit, androgens raise red cell mass, and the rise is dose-dependent
- Monitor: Blood pressure
- Monitor: Lipids, especially a fall in HDL
- Monitor: Total and free testosterone, LH and FSH
- Monitor: Oestradiol, for the aromatising compounds
Cautions
- Polycythaemia or any tendency to a high haematocrit
- Prostate or breast cancer
- Trying to conceive
- Pregnancy
Status
Veterinary only. Schedule III in the United States. Banned in sport at all times.
