Libido and testosterone
Is it generally safe to say, if libido is good, test is in a good range? Similarly, if test is high, libido is good too? If these are somewhat true, taking libido supps like maca, trib, hornygoatweed, ljack...somewhat increase test too?
Or the flip scenario for people with ED is they have libido, but not enough test to function, hence they need meds?
So am i thinking straight or whack?

trib will increase libido but not test.
BTW how can this thread have over 1000 views in less than 2 hours and only 1 post.

High libido doesn't always mean high test especially in the world of supps. If you natural and don't take any hormone altering supps then I would say it's a safe bet.

I know someone that managed to get an erection and have sex the night before a blood draw that showed him as totally suppressed - total testosterone was 20, LH FSH Free test were all below the ability of labcorp to measure.... at the end of his cycle, and he didn't use viagra/cialis/etc. So maybe libido and testosterone tend to show a relationship, but its not a guarantee

Wow 2000 views and only 5 posts???
Your test levels can be sky high, but if estrogen is crushed then you will have 0 libido.

Kisspeptin-54 Stimulates the Hypothalamic-Pituitary Gonadal Axis in Human Males

Context: Mutation of the G protein-coupled receptor 54 is associated with a failure of reproductive function. The endogenous neuropeptide agonist for G protein-coupled receptor 54, kisspeptin, potently stimulates the hypothalamic-pituitary-gonadal axis in rodents and primates.
Objective: The present study was designed to determine the effects of elevating circulating kisspeptin levels on LH, FSH, and testosterone in male volunteers.
Design: This was a double-blind, placebo-controlled, crossover study.
Setting: This was a hospital-based study.
Participants: Male volunteers (n = 6) were recruited.
Interventions: Each volunteer received a 90-min iv infusion of kisspeptin-54 (4 pmol/kg·min) and a control infusion of saline (0.9%) in random order.
Main Outcome Measure: Plasma LH, FSH, and testosterone concentrations were measured.
Results: Kisspeptin-54 infusion significantly increased plasma LH, FSH, and testosterone concentrations compared with saline infusion (mean 90-min LH: kisspeptin, 10.8 ± 1.5 vs. saline, 4.2 ± 0.5 U/liter, P < 0.001; mean 90-min FSH: kisspeptin, 3.9 ± 0.7 vs. saline, 3.2 ± 0.6 U/liter, P < 0.001; mean 180-min testosterone: kisspeptin, 24.9 ± 1.7 vs. saline, 21.7 ± 2.2 nmol/liter, P < 0.001). The plasma half-life of kisspeptin-54 was calculated to be 27.6 ± 1.1 min. The mean metabolic clearance rate was 3.2 ± 0.2 ml/kg·min, and the volume of distribution was 128.9 ± 12.5 ml/kg.
Conclusion: Elevation of plasma concentrations of kisspeptin in human males significantly increases circulating LH, FSH, and testosterone levels. Kisspeptin infusion provides a novel mechanism for hypothalamic-pituitary-gonadal axis manipulation in disorders of the reproductive system.

I don't think that high libio equals high test, either. I've got normal test levels, but because of my bipolarism, I have a sex drive that would embarass a teenage jack rabbit.
The Truth is, there is no Truth.
