[QUOTE="Nelson Vergel, post: 206412, member: 3"] Please look at post #12 for product [URL unfurl="true"]https://www.excelmale.com/forum/threads/pregnenolone-pharmacokinetics-and-studies-need-for-backfilling-pathways-for-men-on-trt.23543/[/URL] I have not tested my progesterone on 200 mg per night dose of pregnenolone. On vacation until tomorrow. Will do so on Friday. Taking that OTC product I bought on Amazon, my pregnenolone increased from undetectable to 95 ng/dL. Let's see if there is a lineal relationship between dosing and blood level! I used the pregnenolone LC/MS test from Quest (the one I sell on Discounted Labs). Quest says normal range of pregnenolone for men is [TABLE][TR][TD] Adult [/TD][TD] 22-237 ng/dL [/TD][/TR][/TABLE] [URL unfurl="true"]https://www.discountedlabs.com/pregnenolone[/URL] Progesterone testing is more tricky when it comes to values and ranges and what company you are using. Someone mentioned this before. The progesterone lab test range for either LC/MS or immunoassay suck for Labcorp and Quest. Quest: LC/MS: Less than 0.2 ng/mL (milliliter, not deciliter) [URL unfurl="true"]https://testdirectory.questdiagnostics.com/test/test-detail/17183/progesterone-lc-ms?cc=MASTER[/URL] Immunoassay: less than 1.4 ng/mL [URL unfurl="true"]https://testdirectory.questdiagnostics.com/test/test-detail/745/progesterone-immunoassay?cc=MASTER[/URL] They also say "DHEA supplementation causes a false elevation of values in this standard Immunoassay method for progesterone." Labcorp LC/MS (no range provided) [URL unfurl="true"]https://www.labcorp.com/tests/500167/progesterone-lc-ms-endocrine-sciences[/URL] Immunoassay 0-0.5 ng/mL [URL unfurl="true"]https://www.labcorp.com/tests/004317/progesterone[/URL] I think I will include 17-OH progesterone since it has precise ranges and it has been linked to testicular health and function.
