As a naturopathic doctor, I’ve waited my entire career for a supplement line like Bestie. These formulas are exactly what women deserve—clean, without fillers or binders, rooted in clinical science yet deeply aligned with nature. Every ingredient is thoughtfully selected to support female hormones, gut health, and real transformation—not just symptom management. Finally, supplements that reflect the latest in women’s health research and actually work.

Testo Boost Estro Blocker is designed to naturally increase testosterone levels, block excess estrogen, and improve physical performance. It combines key ingredients like Tribulus terrestris, Tongkat Ali, and Fenugreek to boost testosterone production and improve muscle growth, stamina, and energy. Diindolylmethane (DIM) helps regulate estrogen levels, promoting a balanced hormone environment.
By supporting your body’s natural production of testosterone, this product helps you build lean muscle, increase strength, and improve overall vitality. It also blocks excess estrogen, reducing the risk of unwanted fat gain and promoting better hormone balance.
Most men notice increased energy and improved physical performance within the first 2-3 weeks. Muscle growth and fat loss can take a bit longer, with noticeable changes often occurring after 4-6 weeks of consistent use. Results may vary depending on your diet, exercise routine, and individual body response.
If you’re not noticing results right away, it could be due to several factors like stress, insufficient nutrient intake, or inconsistent use. It’s important to follow a healthy diet and workout routine to support the product’s effectiveness. If you still don’t see results after consistent use for 8 weeks, please contact our team. Your satisfaction is our priority, and we offer a 30-day money-back guarantee if you are not satisfied.
As men age or experience prolonged stress, natural testosterone production can decline. This leads to reduced energy, muscle loss, and other symptoms of low testosterone. King Energy helps replenish your body’s testosterone levels, supporting strength, muscle growth, and vitality.
Yes, Testo Boost Estro Blocker is formulated to work well with other supplements, such as protein powders, pre-workouts, and general multivitamins. However, it’s always a good idea to consult with your doctor if you are combining multiple supplements or are under medical supervision.
This product is formulated specifically for men to optimize testosterone levels and block excess estrogen. It’s not recommended for women as it may cause unwanted hormonal imbalances. We recommend consulting with a healthcare provider if you're a woman considering this supplement.
By increasing testosterone and blocking estrogen, King Energy helps promote fat loss, especially around stubborn areas like the belly. When combined with regular exercise and a balanced diet, it can aid in reducing body fat and promoting lean muscle growth.
The formula includes BioPerine, a natural compound derived from black pepper, which enhances nutrient absorption. This ensures your body can effectively absorb and utilize the active ingredients, making the supplement more effective.
