6-OXO or androstenetrione is a “natural estrogen blocker” created by Egopharm. It is sold as a dietary supplement in the bodybuilding industry. Itlower estrogen levels in the body and increase testosterone. Wondering how 6-OXO works, what are its pros and cons and if it is really effective as it claims to be? Here’s a review to help you out.
What is 6-OXO?
6-OXO is a steroidal aromatase inhibitor known as suicidal inhibitor as it irreversibly binds to the aromatase enzyme (an enzyme that aromatizes androgens and creates estrogen). Once aromatase is inhibited, it follows that estrogen is minimized leading to a boost in testosterone.
The ingredient 6-OXO is increasingly more difficult to find and buy due to its strength. Also, 6-OXO must never be used post cycle therapy as it is still considered a steroid. Its steroidal effects can most probably impede with recovery of natural testosterone production.
An 8 week study was conducted at Baylor University to identify the effects of 300 mg or 600 mg of 6-OXO used by resistance trained men. The study displayed a boost of 90% for 300 mg group and 84% for the 600 mg group. The study determined that the ratio of free testosterone to estradiol increased considerably.

The ingredient 3, 6, 17-androstenetrione is usually used in testosterone builders and estrogen blockers but have no weight loss or fat loss effects. 4-Androstene-3, 6, 17-trione is a lasting estrogen blocker that can be gauged during urine testing. When estrogen is obstructed, luteinizing hormone (LH) is released and testosterone production takes place.

- Acne – an increase in testosterone, DHT or changing hormonal levels can lead to acne (especially in the shoulders and back)
- Does not totally impede estrogen
