Somehow taking a lower dose of androsterone (2 mg) seems to work better than a higher dose (5 mg) It seems that for me a ratio of pansterone/androsterone should be closer to 3:1 instead of 1:1.
That's actually what the study on synergism of DHEA/androsterone found - 3:1 ratio in favor of DHEA worked best. The 1:1 ratio produced spectacular results but for some reason the study authors thought those were absurd and focused on the 3:1 ratio.
