Standard female dose: <strong>50 mg once daily for 5 days starting on cycle day 2-5<\/strong>; if no ovulation, dose increases by 50 mg in subsequent cycles to a maximum of 150 mg\/day. Standard male dose: <strong>25-50 mg every other day or daily<\/strong> for several months, monitored by serum total testosterone and LH. <strong>Maximum 6 cycles in women<\/strong> (longer use is associated with reduced cumulative pregnancy benefit and theoretical ovarian risk). <strong>Celosv\u011btov\u011b pod odborn\u00fdm dohledem.<\/strong> Multiple pregnancy rate is 8-10% (mostly twins).

Unlike testosterone replacement, clomiphene preserves the natural HPG axis and spermatogenesis. Should be supervised by an endocrinologist or men&#8217;s-health physician with baseline and 6-12 week bloodwork.<\/p>\n<h3 class=\"wp-block-heading\">Co d\u011blat p\u0159i poruch\u00e1ch zraku?<\/h3>\n<p><strong>Stop clomiphene immediately and contact your prescriber.<\/strong> Visual disturbances (blurred vision, flashes, scotomata) affect 1-2% of patients and are usually reversible if the medication is stopped &mdash; but rare cases of persistent visual changes have been reported.

Modern evidence (PPCOS-II trial) shows letrozole gives higher live-birth rates than clomiphene in PCOS, with no thin-endometrium effect and a lower twin rate. Many specialists now use letrozole first-line in PCOS; clomiphene remains first-line for non-PCOS anovulation and is the licensed indication in most countries.<\/p>\n<h3 class=\"wp-block-heading\">Can Clomisign be used after anabolic steroid use (PCT)?<\/h3>\n<p>Yes &mdash; clomiphene is a backbone of &#8220;post-cycle therapy&#8221; protocols designed to restart endogenous testosterone production after AAS-induced HPG-axis suppression. Common protocol: 50 mg\/day for 4-6 weeks, often combined with hCG and\/or tamoxifen, monitored by serial bloodwork (LH, FSH, total testosterone, oestradiol). Strongly recommend endocrinologist or experienced men&#8217;s-health prescriber supervision.<\/p>\n<h3 class=\"wp-block-heading\">Where can I order Clomisign online?<\/h3>\n<p>You can order Clomisign 50 mg tablets from MedsBase in pack sizes of 30, 60, 90 or 180 tablets.
