Seroquel absolutely does not require these levels of tests. All antipsychotics negatively impact blood lipids and blood sugar levels. They antagonist adrenal receptors, which are used to control blood sugar.
Most people don't have a problem, but metformin has been studied heavily and basically eliminates the blood sugar problem.
Sexual problems are rare on Seroquel, certainly far less common than SSRIs.
Thrombosis, I have not heard that and won't research. If you're fucking crazy and hearing voices, Seroquel is a good choice. What is better for such people?
At the end of the day, Seroquel is better for controlling anxiety and mood while on steroids or during withdrawal. It is non-addictive, side effects can be controlled with metformin, and the lipid profile, like using steroids and especially tren rapidly return to baseline after cessation.
So no, it's not a terrible idea.
Is valium better? yes. Is it wise to recommend it when addiction is a real possibility? I don't think so.
Seroquel long term is for people with real problems. All the risk discussed are for them the price they pay to so they don't hear voices or hallucinate. We're not talking abou 10 years of usage. We're talking about use while on cycle, and during withdrawal/PCT FOR THOSE WHO NEED IT.
