Thats not clen that is clomid.
Here is a lil exerpt from my book "The Anabolic Game Plan"
Clomid
Another option for reversing the inhibition of natural testosterone production is with the use of clomid. Clomid is the most effective drug for restoring natural testosterone production after a steroid cycle is completed. This drug works by blocking the estrogen receptors in the pituitary and hypothalamus. This means it will work as an anti-estrogen if clomid is used during a cycle but it will be ineffective for raising test levels as it does not prevent inhibition of LH but works well to boost test levels after added androgens have left the body.
Clomid works with the feedback mechanism Hypothalamic Pituitary Testicular Axis (HPTA). Clomid stimulates the hypothalamus to stimulate the anterior pituitary gland to release follicle stimulating hormone (FSH) and luteinizing hormone (LH). FSH stimulates the testes to produce more testosterone while LH stimulates the testes to release the additional testosterone. This action represents the HPTA which causes an increase in our body’s testosterone production that is vital in maintaining muscle mass after a cycle is completed and the exogenous steroid levels diminish causing a catabolic state.
