OK - here is a breakdown of suggestions (IMHO):
1. Stop now and get at least some test to run a "real" cycle. Keep the test and DBol low for the first cycle to make sure your bud has no BAD effects to AAS (20~30mg/day DBol 400MG wk test or so)
2. Read up on PCT. At a MINIMUM search into clomid and nolvadex. These are two basic PCT drugs that will help maintain gains
3. Work out for a few years before hitting the sauce - why you ask? Because your body can only grow so much at a time. In the first year or so, you will (or should if you are eating/training right) grow enough naturally to effectively reduce the potential gains associated with AAS. Once you start leveling out on gains, then AAS can really help you, but you simply aren't there in the begining (especially at 24 when your natural hormones are still high).
4. Tell your bud to research more. He's not too bright to subject himself to potential PERMINATE body damage with what appears to be little or no research.
Thats all from me, and all just suggestions - each to his own. Good luck bro!
