I'm still taking Ralox for the gyno but I have it 90% under control now so I'm continuing to try treatments. As for RU, I buy Kane's 10g RU powder and mix it into a 70%/30% Ethanol/PG vehicle. The headaches you experienced just means that the product is working but if you get heart palpitations, definitely lower the dose or get off it completely.
I also was not able to convince sigmaaldrich.com to sell me the 1 gram of ORM-15341 for $350 but DCchemicals was nice enough to match the price this one time
Going to try ORM-15341 when it arrives because it is very powerful and has a 10 hour half life vs darolutamide which has a 20 hour half life. I have high expectations for ORM-15341. This stuff is worth more than gold (literally). 1 gram of gold = $45). Fingers crossed.
