Block E3 is a shaping cream specifically formulated to fight estrogen dominant fatty areas. Block E3 helps to improve the appearance of fat deposits that cause man boobs (gynaecomastia) as well as improve the appearance of fat pockets on the hips and buttocks of both women and men. Many estrogen blocking supplements come in a pill or powder form, which can be inefficient in delivery and for many are ineffective due to their inability to specifically target the areas most affected by estrogen dominance. Typically this will result in the user taking higher and higher amounts of the pill or powder until they run out or give up, having had little to no affect on their desired sites. Block E3 allows you to directly target the sites most affected by estrogen and begin eliminating them.

Common symptoms of estrogen dominance include:

  • Increased fat deposits and accumulation in isolated regions such as the side of the chest and around the nipple in men (man boobs
  • Increased fat deposits and accumulation in isolated regions such as the hips (love handles), buttocks and triceps in women
  • Increased inter-muscular fat thereby reducing muscle definition (a soft, doughy look)
  • Reduced muscle mass or an inability to make marked increases in muscle mass

Estrogen is a fat soluble hormone and is stored in the subcutaneous fat in the following areas:

Areas commonly affected by estrogen dominance and associated fat accumulation

Block E3 is commonly used by bodybuilders and physique models for pre-comp sculpting and stubborn fat elimination and is a specifically formulated cream for tightening, smoothing and firming unsightly fat deposits that accumulate in hard to shift areas.



There are many causes of estrogen dominance in men and women such as:

  • Increased aromatase activity, converting testosterone to estrogen
  • Excessive stress
  • Obesity
  • Inflammation
  • Reactive toxins and Xeno-estrogens (from petrochemicals, plastics, Bisphenol A (BPA), pollutions, pesticides)
  • Anabolic steroids
  • Certain foods that contain high levels of estrogen (e.g. milk)
  • Medications that cause hypogonadism and have anti-androgenic effects (such as the contraceptive pill)
  • Iodine deficiency

The Vicious Cycle of Estrogen Dominance

One of the key features of estrogen dominance is that it can be a self-perpetuating vicious cycle that can be isolated from the rest of the body. This means that the normal regulation and hormonal modulation pathways can sometimes not be able to control it or even be aware that it is happening in localised areas. Estrogen generated in fat cells and breast tissue is predominately used locally and not transported around the body and therefore does not necessarily activate negative feedback mechanisms and triggering subsequent reduction in estrogen production. The net result means you could be making estrogen without your body realising you already have too much of it in certain tissues.

Aromatase Converts Testosterone to Estrogen

Testosterone is metabolised to oestradiol by aromatase, in the cytoplasm of adipocytes, breast cells, endothelial cells and prostate cells, to increase intracellular oestradiol concentration at the expense of testosterone.

Increased aromatase activity will increase estrogen and lower testosterone and increase the activation of the mainly proliferative estrogen receptors to induce fat cell production in localised tissues.

How to use Block E3

Block E3 contains 3 effective synergistic ingredients to combat estrogen dominance. Block E3 is designed to work locally on regional fat deposits and breast tissue and not systemically (it does not travel through the body). Block E3 is specifically designed to work on isolated pockets of fat and breast tissue.

Massage Block E3 in to required sites in the morning and evening, preferably after showering. Block E3 effects can be enhances through the use of Subcut in the same region to help oxidise fat deposits.
