IdeaLabs Service – Steroid Analysis (hair and/or (toe)nail)

by

Note (5/27/2022): This launch is Part I of a two-part service – steroid analysis in hair or nails. While we have confirmed our ability to analyze steroids in both types of samples, nail steroid analysis is still in its scientific infancy and there are very few publications on the topic. As such, there is very little … Read more

SHBG may be a good test for liver (metabolic) health

by

A very good study, which probably runs counter to the “mantra” most bodybuilders adhere to – i.e. they would say one must keep their SHBG low in order to increase levels of “free” steroids since, the claim goes, only free steroids are active and capable of influencing cells. If SHBG is high, the claim is … Read more

Niacin / niacinamide ratio may be a very good test for bacterial infection

by

A very interesting study, which may provide a cheap, fast and easy method for testing whether a person has a bacterial or not. This is very useful in cases of respiratory diseases where a clinician has to determine if the respiratory infection is of bacterial or viral origin, in order to decide if prescribing antibiotics … Read more

One only needs to talk to a person on serotonergic (SSRI) drugs for a few minutes to realize just how “happy” those people are as a result of their medication. The study below now exposes … Read more

Elevated ESR and hCG levels are strong predictors of impending cancer diagnosis

by

I am posting this study for two reasons. One of them is to corroborate a statement from Peat on the role of inflammation in cancer and the diagnostic value of “non-specific” (as the medical industry likes to call them) inflammatory biomarkers such as erythrocyte sedimentation rate (ESR). https://en.wikipedia.org/wiki/Erythrocyte_sedimentation_rate http://raypeat.com/articles/aging/bleeding-clotting-cancer.shtml “…It is commonly known that the … Read more

While estradiol falls, estrone rises with age and is much more relevant for estrogen-driven diseases

by

I posted a few studies in the past demonstrating that estrone (E1) and especially its long-lasting derivative estrone sulfate (E1S) are reliable biomarkers of both breast and prostate cancer progression/prognosis. However, for some reason the medical industry is obsessed with estradiol and since its levels plummet after menopause this has allowed doctors to declare menopause … Read more
