I have read the thread, though quite some time ago...
Yes, while there is indeed little scientific literature available on HPTA recovery post cycle, there is better advice, anecdotal or not, within that and other threads, both suggesting and addressing directly the issue of recovery. So often, uncontrolled (scientifically speaking) and anecdotally-based research far precedes controlled experimental research. This is the case with these threads.
Rather than relying on an outdated and unsubstantiated adage, I would have been better to reiterate far more experienced user's advice.
Having, myself, always followed an overly cautious approach, I am only beginning to experiment with time as it actually corresponds to the HTPAs recovery (using tests, matched with and prompted by subjective measures of recovery), rather than relying on pre-set guidelines.
Appreciate the correction, as always.
