If he uses lots of Anadrol he won't be around long.
How much is "a lot"?
I've had a few long Anadrol cycles. About a year long, then a week or two off and then a year on again. From 25mg up to 250mg for short stints. One fella on a forum said he's been on 100mg for about 25 years. If you're unlucky you could get those liver cysts that are a problem if they burst or if your liver isn't very robust you could get jaundiced and so on, it's genetic. My liver values have always been in range and many find the same with Anadrol, strangely enough as it's considered more "toxic" than other orals. The biggest issue with roids in general, not just Anadrol, is high BP.
Anadrol is nice in that you just take a little pill and it's like a gram or a gram and a half of testosterone. It's nice if you like feeling strong.
That oldfella here misunderstands the "state of underground Anadrol" these days lol. Just because some take more than one tab a day doesn't mean the stuff is any weaker than in the past. One little Anadrol packs quite a punch, I once had some crude Anadrol pills from "IP" that were sent from Pakistan taped to a card in a letter. I took 20 pills, one a day, and I was 25lbs heavier after, didn't even train once
Doesn't mean you can't take or tolerate more.
Nasser was taking 10 Anadrol a day according to Milos and Chad said he was jaundiced sometimes (Chad said he took 5, Milos said 10, both can be true). And he died but not from Anadrol per se IMO, it's more like the total Androgen load (say he was taking 5 grams of injects on top) and long term high BP.
Hey, long ass post on Anadrol
TL;DR you can live a long time while taking Anadrol.
