Sometimes you just can't help it bro. But maybe you can try injecting the same amount, like 300mg, every 5th day instead of injecting every 7. Blood levels should stay a little more level at this rate.

Get a back scrubber and take a shower 2x daily. Use antibacterial soap such as "safe guard" keep in mind majority of bath soaps are simply "deorderant soaps" and do not contain antibacterials. Gotta look at the label closely.

Since making the switch I have had clear skin.

up the adex to .5 or get another brand of adex

Well, acne can be a sign of high estrogen, have you done any blood work and verified your arimidex is working properly?

For me acne is just part of my genetics, without accutane my body is going to produce oil and im going to break out theres only so much i can do. I find Retin A cream helps out alot with small dose of antibiotics.

But yes, test will give you oily skin and if your prone to breakouts then it can cause some nasty cystic acne.
