shared by Nathan Goodyear on 30 Apr 12 - No Cached
  • Since salivary cortisol concentrations were shown to reflect the free, biologically active fraction in plasma, salivary assay may, in selected cases, provide results of greater diagnostic significance than plasma total concentrations.

    salivary cortisol found to be superior to total serum cortisol levels.

  • The assessment of cortisol in saliva has proven a valid and reliable reflection of the respective unbound hormone in blood. To date, assessment of cortisol in saliva is a widely accepted and frequently employed method in psychoneuroendocrinology

  • Nathan Goodyear on 15 Nov 11
     
    appears that PTSD results in divergent catecholamine and cortisol levels as patients age.  The catecholamines (norepinephrine) will elevate and the cortisol will progressive decrease.  Additionally, this is revealed in salivary cortisol testing

Tongkat Ali long jack cortisol stress testosterone hormone hormones

shared by Nathan Goodyear on 09 Mar 15 - No Cached
  • At the age of 60, testosterone levels are typically only 40-50% of youthful levels and may be lower
  • Eurycoma contains a group of small peptides referred to as “eurypeptides” that are known to have effects in improving energy status and sex drive in studies of rodents
  • The effects of tongkat ali in restoring normal testosterone levels appears to be less due to actually “stimulating” testosterone synthesis, but rather by increasing the release rate of “free” testosterone from its binding hormone, sex-hormone-binding-globulin (SHBG)
  • ...6 more annotations...
  • The current study found that daily supplementation with tongkat ali root extract (200 mg/day) improves stress hormone profile (lower cortisol; higher testosterone) and certain mood state parameters (lower tension, anger, and confusion)
  • tongkat ali supplementation (100 mg/day) improved lean body mass, 1-RM strength, and arm circumference to a significantly greater degree compared to a placebo group.
  • In a recent 12-week trial [46] of Eurycoma longifolia supplementation (300 mg/day), men (30–55 years of age) showed significant improved compared to placebo in the Physical Functioning domain of the SF-36 quality of life survey
  • sexual libido was increased by 11%
  • In men with low testosterone levels (average age 51 years), one month of daily supplementation with tongkat ali extract (200 mg/day) resulted in a significant improvement in serum testosterone levels and quality-of-life parameters
  • rise in cortisol and drop in testosterone is an early signal of “overtraining”
  • Nathan Goodyear on 09 Mar 15
     
    Tongkat Ali, commonly known as long jack, is found to reduce stress and increase Testosterone.  Stress is one of the common causes of low T in men.  It appears that long Jack functions as an adaptogen.

  • Nathan Goodyear on 14 Mar 18
     
    Older article, but good one still on hormones and overtraining.  Look to the Testosterone/Cortisol ratio.  OTS will lead to decreased Testosterone and increased cortisol resulting in chronic catabolic state.

    LC-MS/MS shown to be useful in evaluation in people with suspected elevated cortisol levels.  In this study, they found the dexamethasone suppression test was required.  The point however is that cortisol is a valid medium and this was with LC-MS/MS instead of the more commonly used ELIZA technique.

  • Nathan Goodyear on 19 Feb 13
     
    long endurance competitive events associated with catabolic hormone balances found in a low T:C ratio.  This occurs primarily through an elevation in cortisol and small drop in Testosterone.  The recovery phase is anabolic through a rise in T:C, primarily through a return to baseline by cortisol and an increase in Testosterone.
