Gyno from Astaxanthin

I started taking Astaxanthin about three weeks ago 30-40 mg/day as an antioxidant. Discontinued it due to sudden gyno development, nipple pain, and fat accumulation in midsection. Even noticed some mood changes and depressive thoughts. Since I was on it for a little over two weeks, would it be smarter to let my body rebalance itself, or should I see a physician now to get a prescription for tamoxifen or something similar? Don’t want to create a yo-yo effect with my hormones but this is miserable and unacceptable. Mid thirties male on keto diet and regular RT.

Highly doubtful you developed gyno after 3-4 weeks! Correlation does not equal causation.

Eat some broccoli every day and deadlift heavy on a regular basis.
