Bio-Identical Testosterone??


#1

What's the skinny on bio-identical T? In looking around I can't tell what the difference is between bio-identical and regular test-cyp other than test-cyp being bound to oil. Will it shut down natural production the same as regular T?

All very confusing, as per usual with anything hormonal.

Thanks for responses.

Yes, of course it will. ALL endogenous T and its derivatives will shut down your pituitary and testicles.

Testosterone esters in oil are slowly absorbed from injection sites and then the ester groups are removed. So you have a time release bio-identical testosterone delivery system. Many docs like to mislead guys about this or they are simply stupid.

Any increase in your T levels will tend to shut down your own production. You can’t take a little bit to increase T levels, you need to replace all production.

Thanks for bringing some clarity to it guys. The bio-identical T sounded like a crock to me, thanks for weighing in and confirming.

“Bio-identical” is also sales pressure to use transdermal T products and sometimes pellets.

I think that’s dead on KSman. This dr. was giving a “too good to be true” sales pitch with bio-identical T as a miracle drug.
