Two things.
Did I read it..yes..stay on topic on we are looking for proof that Anavar will shut down HPTA. The link I posted that KelKel provided says opposite i.e. that in some situations it actually stimulates HPTA. Correct use and protocol are key.
testosterone levels (358 ± 119 ng/dl in the oxandrolone group and 421 ± 196 ng/dl; P = 0.26). There was a trend toward a greater decline in LH levels with oxandrolone, suggesting that oxandrolone treatment may have suppressed the hypothalamic-pituitary-gonadal axis.
None of these guys on 20 a day for this period dropped out of range low. Suppressed..possibly but the changes in LH were not documented that I saw..looked for it but did not see a graph or chart. Useing testosterone as the measure of the change....healthy people can fluctuiate testosterone levels this much from time of day tested, diet changes, WBC changes, etc etc.
But the good thing to take form this is a 24 week test using 20 mg daily as the base shows that it did not shut down HPTA and kept all the subjects in the normal range.
So agan POSSIBLE negative impact to HPTA but by no means suppressed completely. If you are young dumb and full of mayo your Test levels are 750+ easily and the hit would be almost negligible. Using people that are 60-80 made the hit seem worse....which is a good test because you took the lowest common denominator and it passed.
