Are you a weight class athlete? If you are at the top end of your weight class, adding in the drol might add a few lbs in a week so just keep that in mind.

Low dose test, moderate tren, and anadrol has always been the king of strength cycle for me. I'm also a powerlifter and have tinkered with lots of different strength cycles and nothing comes close to this. Something like 375 test, 400-500 tren e, and 50-100 anadrol is typically what I run. I also like the idea of slowly revving up the dosages throughout the prep. In a strength cycle, that is ideally what should be done. My cycles are usually 12 weeks with 375 test, 400 tren e, and 50 mg anadrol for the first 3 weeks just to kickstart the strength gains. At week 3 I will drop the drol and keep the rest the same until week 6 where I might bump the tren from 400 to 500, but will keep test the same throughout. At week 8 I will begin the anadrol again at 50/day for 2 weeks, then maybe 75/day for a week, and 100/day for the last week if I can handle it. I can't run anadrol for very long or at very high dosages because it fks up my stomach after a few weeks to the point where I can barely eat the calories I need to. I dunno how many of the top powerlifters can run drol at 200-400/day for weeks on end. I know and have spoken to many of them and this is what they tell me is very common. Seems a bit overkill though.

Test/tren/drol is considered a harsh cycle for many, but for me, it works perfectly. I don't become emotionally unstable, no anger issues. But my aggression in the gym is unlike anything else. My bloods are always in check and my blood pressure never gets too crazy either. I am also one of the lucky few who get all of the positive sides of tren with very little negatives. Adding the drol gives me a super boost of strength. Nothing gives my mind muscle connection and CNS a boost like drol does. I know press says it isn't a CNS simulator, but from what I've read, experienced personally, and the people I've talked to, drol is one of the best CNS boosters. Is this a cycle I recommend for anyone going for a PR? Absolutely NOT. But, if you are a competitive powerlifter and are looking purely for strength, then this gets the job done. Just keep an eye on your bloods, donate regularly, and don't be afraid to stop your cycle or switch compounds if you feel like dogshit.

For powerllifting I think you would want to work some halo in there at the end, especially pre-meet. But, what do I know, I am just a bodybuilder.
Good luck with the cycle and comp.

Your best guy to ask about this is @Toproll as he specifically runs this cycle when he competes so will know best when and how to dose it. I've always found Anadrol an unpredictable compound for strength - sometimes I have done great off it and other times less so. I personally think bumping it to 100mg 3 days before is leaving it too late, as its a strength builder rather than a stimulator of the CNS. I think you would be best doing that weeks before to get the best strength gains from it as its renown to give much better (almost twice) as much strength at 100mg/ed as it is at 50mg/ed. Get to grips with it about five weeks before and see how you are. I would start at 50mg also, 25mg doesn't really give a proper feel for it and gives the impression its very easy to live with when really I don't think it is. I guess there is also the factor of weight if you need to drop some pounds beforehand - although Adrol isn't the huge mass gainer its made out to be imo.

@press1 this question is all yours
