Steroid creams
The Clomid should easily have been able to overcome normal estrogen levels, and so if the estrogen- only theory of inhibition were correct, Jim should have been suffering no inhibition. steroid creams Steroid creams. But the fact is, his testosterone levels dropped to only 1/10 his baseline value. Estrogen alone was not the cause of his inhibition. It could not have been the cause of any of it, given the normal levels and the Clomid use. steroid creams Us steroids. So much for the estrogen-only theory of inhibition that has been claimed by other writers. That isn't to say, though, that estrogen is not also inhibitory: it is. What then besides estrogen can cause inhibition? DHT, which does not aromatize, has been extensively shown to cause inhibition of testosterone production. steroid creams Bodybuilding pictures. Androgen alone, then, is sufficient to cause inhibition. In Jim's case, androgen use was moderately heavy, and androgen alone would seem the cause of the inhibition. Progesterone is another hormone that can cause inhibition, when used long-term. Paradoxically, in the short term it can be stimulatory. Other relevant factors include beta agonists, opiates, melatonin, prolactin, and probably other compounds. With the exception of beta agonists (e. g. ephedrine and Clenbuterol) and opiates (natural endorphins on the one hand being inhibitory, and Nubain blocking such inhibition) manipulation of these would not seem useful in bodybuilding. The Hypothalamic/Pituitary/Testicular Axis (HPTA)To understand inhibition of testosterone production, we need to know first how it is produced and how production is controlled. The broad general picture is that the hypothalamus receives a variety of inputs, for example, levels of various hormones, and decides whether or not more sex hormones should be produced. If the inputs are high, for example, high estrogen or high androgen or both, then it decides that little or no sex hormones should now be produced, but if all inputs are low, then it may decide that more sex hormones should be produced. It seems that the hypothalamus doesn't respond only to current hormone levels, but also to the past history of hormone levels. The hypothalamus itself cannot produce any sex hormones - instead it produces LHRH, or luteinizing hormone (LH) releasing hormone, also called GnRH (gonadotropin releasing hormone. ) This then stimulates the pituitary gland. The pituitary uses the amount of LHRH as one of its signals in deciding how much LH it should produce. Proper response depends on having sufficient receptors for LHRH. These receptors must be activated for LH to be produced.
