I can't hypothetically compare the chance for acne on Primo 600mg or 200mg Tren.

I wouldn't recommend it if it was insane on the sides. It's hyped up. Try it @ 200mg/week am sure you will be happy with the results! 350mg Ace/400mg Enanthate is where you start feeling the real effects of the drug though. 200mg should be enough to just further stimulate some ARs and won't be heavy at all on the sides if you even get any..
