I am on a course of 500 mg/week enanthate + oxymetholone, already in my third week, my breasts are a little sensitive, my nipples are hardening, and I feel a slight swelling. I don't want to wait for full gynecomastia, because then it's hard to get rid of. I am considering adding tamoxifen as a preventive measure, as I have heard that it blocks receptors in the breasts better than aromatase inhibitors. What is the dose for prevention, and can it be combined with letrozole?

On an aromatized course, tamoxifen 10-20 mg daily is the best for gynecomastia prevention because it blocks estrogen in the breast tissue, preventing it from developing. I always take 10 mg of tamoxifen from the first week at 500-600 test – my nipples are calm, no swelling throughout the entire course. If you already have sensitivity, increase to 20 mg for 7-10 days, then back to 10. It can be combined with letrozole, but it is not necessary, tamox alone is sufficient. I was also once interested in the tamoxifen price per pack because I didn't want to overpay, and I found it on Redmond Pharm – a pack of 30 tablets of 20 mg each is reasonably priced, pharmacy quality, and comes without any questions. Start with 10-20 mg and monitor your condition.
