How do Site Oils work? To begin with, they do not stay in the muscle for 3 to 5 years. They get dissipated within months. However, during this time, they have stretched the fascia of that muscle. The fascia is a great constrictive factor in muscle growth. The more stretched the fascia is the more the muscle will grow and the more it will have that `popping' look. Site oils stay in there long enough for the fascia to stretch. As they dissipate, the `space' left by them is replaced with new muscle tissue growth. That is the reason why when x-rays where performed on some of the people that have 25"+ arms, there was no oil found in there. The oil dissipated and it was replaced by real muscle.
The principle is the same as the one behind site shots with steroids, but it works at a much a larger degree, because the Site Oils take that much longer to dissipate.
THOUGHTS? HE SAYS THE 'YEARS' ISN'T TRUE IT IS MONTHS.
