    SSRI drugs decrease androgens / progestogens, increase estrogens

    As hard as it is to believe, this is the actual title of the study - i.e. SSRI drugs are bonafide endocrine disruptors. As it turns out, all of the six most-prescribed SSRI drugs the study looked at behaved not only as inhibitors of gonadal androgen synthesis (e.g. testosterone, DHT), but also...

    AlloP - Liquid Allopregnanolone For Lab/R&D

    Just a quick announcement that we have replaced the 5α-DHP in our store with allopregnanolone. The main reason for switching over to allopregnanolone is that we always wanted to provide that steroid right from the start, however we could not find a lab willing to synthesize it. Thus, 5α-DHP...

    Ketamine Cures Depression By Reducing Serotonin, Increasing Dopamine

    As many of my readers know, FDA recently approved the party drug ketamine (known as Special-K on the street) as a rapidly-acting antidepressant. The rapid antidepressant effects of ketamine have been known since the 1960s but FDA denied that those effects are relevant in humans and refused to...

    Antidepressants Are Physically Addictive, Should Not Be Taken Long-term

    What is surprising about this study is not that antidepressant drugs are addictive. We have known this (despite the vehement denials from pharma executives) even way back before those drugs got approved for human use. What is surprising in this study is that for the first time there is an...

    FDA Approves Allopregnanolone As A Fast-acting, Long-lasting Antidepressant

    As many of forum users know, one of the real mechanisms of action of the SSRI drugs is not the increased serotonin but the increase in brain allopregnanolone these drugs cause. As such, there has been (secret) interest from Big Pharma for years in both allpregnanolone and its synthetic...

    Allopregnanolone May Soon Be Approved As A Fast-acting Antidepressant

    The patents on most SSRI drugs have either expired or are close to expiration. Lately, there have also been a number of high profile cases obtaining favorable court outcomes by blaming SSRI drugs for a host of human criminal behaviors or adverse health events. As such, Big Pharma is desperate to...

    Massive Study Says SSRI Drugs Are BOTH Ineffective And Dangerous

    Environmental Enrichment As Effective As Drugs For Treating Depression

    This study is really good because not only it states directly that depression can be directly caused by stress, but also because it shows that environmental enrichment (EE) for just 20 days can be at least as therapeutic as drugs. The beneficial effects of EE are well-known in psychiatry and...

    Peat was asked a few times about his opinion on SSRI drugs and he said that 1) he does not recommend them because they are systemically serotonergic, and 2) their mechanism of action is really not what big pharma would have us believe. Since then, SSRI drugs that have been shown to actually work...
