I like to run 1-AD with injectible long-estered test.
Years ago, I had great results with 1-AD, and also the classic 1-AD / 4-AD stack.
Now, 4-AD is quite a disappointing source of testosterone, it has short half-life and causes a lot of estrogeny bloating. 1-AD with "real" test works much better.
Let me explain why I still use 1-AD when we can get pretty much any steroid on the internet.
1) It's a great dry bulker
2) It's not 17-a methylated, so it has no liver toxicity
3) It has a 1-2 double bond, so a good amount survives the liver first pass. Primobolan also has this double bond, which is why it too is orally active.
4) 1-AD is very cheap compared to primo tablets.
5) I've never read this anywhere, but I believe 1-AD (or 1-test) has an aromatase inhibiting effect, maybe slightly weaker than proviron. It definitely seems to reduce the moderate bloat from the testosterone.
My current cycle is 500mg test enanthate / week (10 weeks), with an oral turinabol "kickstart", and an oral "kickstop" (probably MHN or Anavar). I'm injecting small amounts of Human Chorionic Gonadotropin (HCG) twice weekly to keep the boys in the barracks, and to make post cycle therapy (pct) easier when it starts at the end of week 12.
The great thing about 1-AD is that you can run it, bookended by two methylated orals, yet still give your liver enzymes time to recover.
In this way, it's my cheap Primo. Taking pills every day forces me to train - I don't want to waste them, if you know what I mean.
1-AD was the pinnacle of the "true" prohormones (it converts to 1-testosterone via a decent enzymatic pathway) and works well, but it's very dry and shuts you down quick. I think it's still the best way to get 1-test into yourself (injections are notoriously painful, and M-1T is another proposition entirely, with many side effects)
1-AD / 4-AD was an okay combo, but 1-AD / test enanthate go together like a horse and carriage.
