Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes. 
Although both are nutritious, if you want to consume milk as part of your muscle building diet, to meet your protein requirement, choose buffalo's milk over cow's milk. Firstly, buffalo milk is much more easily available than cows milk. Secondly, Buffalo's milk scores slightly better in protein content than cow's milk. While the difference is not huge, but it will certainly add up. A few people would be concerned about the high fat content in buffalo's milk. For this, chose low fat options. If you are only chasing size and looking to increase you calorie intake, choose whole fat. Keep in mind that the fat in milk is majorly saturated which is not a matter of concern. Men require saturated fat to produce testosterone. If your overall saturated fat intake from other sources is not too high, pick whole fat milk. Though taste varies with every individual, generally buffalo's milk is considered to have better taste.
After the double-murder suicide, former wrestler Christopher Nowinski contacted Benoit's father, suggesting that years of trauma to his son's brain may have led to his actions. Tests were conducted on Benoit's brain by Julian Bailes, the head of neurosurgery at West Virginia University, and results showed that "Benoit's brain was so severely damaged it resembled the brain of an 85-year-old Alzheimer's patient." He was reported to have had an advanced form of dementia, similar to the brains of four retired NFL players who had suffered multiple concussions, sank into depression, and harmed themselves or others. Bailes and his colleagues concluded that repeated concussions can lead to dementia, which can contribute to severe behavioral problems.
