Buy Antiestrogens PCT online Australia. Antiestrogens are estrogen receptor antagonists at the hypothalamic level, increasing GnRH secretion, and at the pituitary level, increasing FSH and LH gonadotropins, by blocking the negative feedback of estrogens, generated mainly after aromatization of testosterone, thus stimulating spermatogenesis and steroidogenesis.⁶

Empirical treatment with antiestrogens (tamoxifen 20 mg/24 h, clomiphene 50 mg/24–48 h) increases the pregnancy (OR 2.42, 95% CI 1.47–3.94; p = 0.0004), concentration (MD 5.24, 95% CI: 2.12–88.37; p = 0.001) and sperm motility (MD 4.55, 95% CI: 0.73–8.37; p = 0.03) rates according to a published meta-analysis.¹¹ Another recent meta-analysis, less methodologically rigorous, confirms these results.¹² The incidence of side effects does not differ from that of placebo, although gynecomastia, headache and hot flushesare possible.¹¹ The advantages of using antiestrogens in clinical practice are their low cost and their reasonable safety profile.
