(The same goes for muscle size.) There’s no reason why someone of lower testosterone couldn’t be stronger than someone of greater testosterone.
Recent studies that used different research designs show conflicting outcomes. A study from Norway showed that by raising blood hormone levels by training a high volume of legs prior to arms, it’s possible grow muscle and gain strength to a greater degree than if the hormones are at resting levels.

Relationship between testosterone and muscle growth [closed] Ask Question. While increasing testosterone levels above natural levels with the use of steroids can help add appreciable mass, increasing T levels within the natural range does not seem to have the same effect. Is muscle strength 100% correlated with testosterone levels? 0.
Jul 06, 2012 · Yep – Testosterone levels can fluctuate quite a bit from day to day and as a result of many other factors. Throughout the day wouldn’t be accurate as levels are highest in the morning, while levels usually decline as the day goes on (evening).
Dating The Weird Benefit of Low Testosterone Levels A new study shows that having a supportive social network is correlated with lower testosterone levels.
Apr 03, 2014 · In addition to altered testosterone levels, the growth hormone action of muscle mRNA IGF-1 is also impaired . Low levels of these anabolic hormones in patients undergoing dialysis affect muscle protein balance negatively leading to a reduction in muscle strength and impaired physical function [11, 12].
Changes in leg press strength, leg power, thigh and quadriceps muscle volumes, hemoglobin, and IGF-I were positively correlated with testosterone concentrations, whereas changes in fat mass and plasma high-density lipoprotein (HDL) cholesterol were negatively correlated.
Nov 22, 2008 · And testosterone levels can be a real concern as a male ages, not from a training standpoint, but from a virlity, stamina, general mood, libido and mental sharpness point of view.
Testosterone, body composition and aging. In addition to growth hormone (GH), sex hormones are important determinants of body composition.

A systematic review and meta-analysis by Stockton and others  evaluated effect of vitamin-D supplementation on muscle strength. It was concluded that vitamin-D supplementation does not significantly effect muscle strength in vitamin D saturated adults.
NOTE: But you CAN jack up and maximize levels of testosterone naturally. I have put together a short guide that will reveal 8 ways to optimize test levels so that you can have more lean muscle, increased strength, increased energy levels and less body fat.
There has been a continued review of testosterone treatment for HIV infected men and the results have always correlated with an increase of lean muscle mass and lean overall body mass. Not only that, there were other key improvements across endpoints such as mood, strength, fatigue and overall general quality of life.
