Second, this is a methylated testosterone product. Simply put all mammals have receptors that bind with testosterone. In order for the testosterone molecule to bind with the receptor it has to have a certian structure. Any change in the structure of that molecule runs a very high risk of inhibiting it's ability to bind with the receptors in the body. This is further proven by the claim that M1T passes through the liver unchanged. If this product is capable of binding with receptors within the body, it should also bind with the receptors in the liver that would normally denature it. If it makes it through the liver unchanged, then I doubt it seriously if there is any significant binding to steroid receptors within the body.
