None of these links are 25R-diol. They are talking about generalities of starting compounds. Yes many things are synthesized from diosgenin including DHEA.
If there was a study that was for 25R-diol that is one thing, but this is generalities about diosgenin (which 25R-diol is not, its altered to a form of DiHydroxy Diosgenin, which really changes things).
Nothing in our University Study or other bloodworks over the years even hint that it is suppressive. Its not. Not being rude either, don't take it that way. Its kind of like saying Creatine makes you bloated. Sure some do, however many forms do not. Too general.
You won't find anything in Pubmed that is an exact 25R-diol match, like Sinner said earlier.
while you are right about its uniqueness, there arent any articles except the one you guys have about it not being supressive,
but this also leads back to to BROMO concept, in which there arent many articles saying that it wont convert to an anabolic/androgenic.
if something like diosgenin can be synthesized into DHEA and other hormones, then yes it could raise testosterone, but without it being suppressive is something different.
you have something saying it raises testosterone, not that it can be used without PCT, same thing as with bromo, Theres such little published articles on the things you market, other then what you have, you have word of mouth. all is good, but still need some conclusive evidence on what happens AFTER the cycle is over, how low levels drop, if they drop, full hormone panel.
doesnt mean it doesnt work and i dislike the product, but to be safe, if something is an anabolic, raises testosterone, it may infact need PCT. even if it poses no androgen potential.
Something all natural (that doesnt supress you) that works, are few and far between, maybe u guys have the only magic formula with your unique formulations, but i doubt that they dont need PCT, i believe some will be needed.
