Why are you concerned about the long half-life if your goal is a long bulking cycle and you’ll be going back on cruise afterward anyway? If you’re worried about doping control, that’s a different matter. But the data you mentioned about detection times in months is outdated, and with modern testing methods the detection window is now much longer. If you want, I can explain this in more detail.
Regarding your idea with Dbol. I’ve also heard about its effect on glycogen, but in reality it’s just one of those gym ideas that someone came up with and that has no scientific basis. There are no comparative studies showing that Dbol increases muscle glycogen or ICW more than exposure to other androgens. Its reputation as a drug that quickly “fills out” the muscles can be explained by its pharmacology and practical observations, but unfortunately the claim that “Dbol is especially good at loading glycogen” has no real evidence behind it, even on a theoretical level.
If the goal is specifically to maximize muscle glycogen + ICW rather than simply increase total body weight/water, much more direct factors are carbohydrate intake, training, creatine, and sodium/hydration. Dbol isn’t some kind of specific glycogen drug.
As for the high doses of growth hormone and testosterone used by pros — yes, this is practiced, but 2–5 grams is more likely the total androgen dose rather than testosterone alone. These days, more and more pros are moving toward more reasonable doses. But if we’re talking about doses used 10 years ago, then yes, many people were running amounts like that.
Growth hormone is a very controversial topic in general. Even for a pro, more than 10 IU is excessive. There isn’t much additional benefit, you spend a lot of money, and at those doses the side effects can really go beyond any reasonable limits. Honestly, it can do more harm than good. I can break this down in more detail too.
In short, the less, the better, and this applies to any dosage. To handle huge doses of steroids, you need unique genetics. If you don’t have that, then after a certain dose the results actually get worse. I’ve seen this firsthand working with my clients.
