I have heard this also, but with the benefits of cholesterol reduction (which is a know problem of sdrol) i thought it was a good idea. Obviously you feel that the risk outweighs the reward though. Feel free to elaborate, I'm all ears.
The cholesterol issues is probably due to the change in gene expression in the liver which tends to be more pronounced with orals. Also too the fact that natural testosterone is being suppressed could possibly mean that there is more cholesterol floating in the blood.
cholesterol->dhea->testosterone.
That is a really trimmed version.
Probably your best bet is:
10g+ of fish oil
100mg of Coq10
600mg of SAMe
Hawthorn Berry, although that is questionable.
Milk Thistle, although that is also questionable.
There is Vytorin that is perscription for cholesterol, but that is a controlled substance so there is a good chance you won't be able to get your hands on that.
Then there is also Nexavar that is perscription for the liver, but that is also a controlled substance.
I suppose keep your fingers crossed and good luck.
This is exactly the reason why I don't do orals.
Pretty much all orals is about damage control. There isn't really a lot you can to do 'protect' yourself per se, at best, maybe put safety slightly in your favor. A lot of people just go modest on their cycles/doses, wash down the SERM, and hope for the best.
