Androgenic receptors

hi everyone



So mike Arnold says in an article that we only have enough receptors for about 3.5g test per week, after this, you wont get any additional muscle gains but side effects will increase.



But i'm confused.. some advanced bodybuilders might run 100mg tren ace everyday and add extra compounds such as dbol. This can easily add up to more than 3.5g test equivalent, so why do people run such high dosages? we can only absorb so much with our receptors...



Is it because steroids work by other mechanisms in the body apart from the androgen receptors?



Thanks
