No matter what you may have heard, unfortunately ALL AAS inhibit HPTA.
If you want to know which might have the least impact, I'd say Proviron up to 75 mg/day and dbol in a low 5 to 10mg AM dose. But if you want to go on a 100% sureness, no AAS during recovery.
Agreed. Anavar will at least suppress the HPTA. I also think it has a longer half-life (maybe 8 hours), so even if it is taken in the AM it will still be in your system at night.
