Product Description:
What it is and How it Works
Boldenone Undecylenate, commonly known as Equipoise (EQ), is a long-acting injectable anabolic steroid originally developed for veterinary use. It is structurally similar to Testosterone but has a modified chemical structure that reduces its estrogenic activity and enhances its anabolic-to-androgenic ratio.
EQ increases protein synthesis, nitrogen retention, and red blood cell production, leading to steady improvements in strength, lean muscle mass, vascularity and endurance. Its long ester provides a slow and stable release, making it ideal for longer cycles.
Side effects are generally milder than with stronger androgens, though they can include acne, oily skin, hair loss in those genetically predisposed, appetite increase, and cardiovascular strain. Estrogenic side effects are possible but less pronounced than with Testosterone.
How is it used?
With its undecylenate ester, EQ has a very long half-life, requiring injections only once or twice per week. It takes time to build up in the system, often 4 to 6 weeks, but provides smooth, consistent gains without sharp hormonal spikes.
It is commonly stacked with Testosterone and other compounds to enhance lean mass while minimizing water retention. Because of its slow action, cycles with EQ usually last 12 to 16 weeks for maximum benefit.
Dose
This product is dosed at 300mg/ml × 10ml. Performance users typically run 300 to 600mg per week, often stacked with Testosterone. Some advanced users go higher, though increased doses raise the risk of side effects, especially elevated red blood cell count and blood pressure.
Advice From BTW
- Long cycles only
EQ works slowly, so plan for at least 12 weeks if you want to see real results.
- Monitor hematocrit
EQ significantly raises red blood cell count, which can thicken the blood and increase cardiovascular risk. Donate blood if needed.
- Appetite booster
EQ often increases hunger, which can be helpful in bulking but problematic during a cut.
- Stack smart
Works best alongside Testosterone, and can be combined with other compounds depending on goals.
- Patience pays
Gains are steady and quality, not explosive. EQ is for slow, sustainable progress.
FAQs
- How long does it take to see results with EQ?
Typically 4 to 6 weeks, as the undecylenate ester releases very slowly. This is why longer cycles are recommended.
- Does EQ aromatize to estrogen?
Yes, but at about half the rate of Testosterone. Estrogen-related side effects are possible but usually less severe.
- Is EQ good for bulking or cutting?
It can be used for both. Its lean, steady gains make it excellent for clean bulks, while its minimal water retention also works well for cuts.
- What is the biggest health risk with EQ?
Elevated red blood cell count, which can strain the cardiovascular system. Regular bloodwork is essential.
- Can EQ be used alone?
It can, but it is almost always stacked with Testosterone for balanced results and to maintain normal physiological functions.
