Not really. Milk Thistle alone is not enough protection, even for 40 mgs for a month.
I'd suggest OP should look into N2GUARD, HOWEVER, I do think he hasn't been training long enough to even consider steroids. That's not a judgement call. Without a foundation, it's not only a waste of time money and potential health, it'll slow future progress. He needs at least another year and can make more solid gains using the right training, the right supps, and the right diet.
