@soya, I’m not sure you’re able to manage test C at all man. Your dose is so much lower than standard and you’re still having acne issues - I’m getting the impression you will have this reaction no matter what dosage tbh.
Time to visit a dermatologist for the skin issues. Get your hormones balanced and optimized and then worry about skin quality. Hell, some issues could stem from fluctuations in your hormones troughing and spiking with minimal test.
