  Is Insulin Needed for Muscle Growth?
Mar 17, 2010
Everybody says that ingesting carbs with amino acids is the best way to make muscle grow. Not true.
  Exercise intensity and the time course of protein synthesis
Mar 11, 2010
To stimulate muscle growth, you have to have the right combination of exercise intensity and nutritional signals. This does not mean you consume carbohydrate; you consume the key amino acids within the right time frame.
  Protein Synthesis, Energy Expenditure, and Inflammation
Mar 4, 2010
I have a lot of muscle, which raises my resting energy expenditure. I burn 300 to 365 more calories every day than the average person my age even when I'm doing nothing (something I do quite a lot). This difference, conservatively, translates into more than 10 pounds of fat per year. 
  "Hard" Gainers
Feb 25, 2010
Naturally, individuals will gain muscle in different ways. Some may achieve large mass while others may not.

But, there is often a common element for hard gainers who work out long and hard and take all the supplements and yet gain little. I think I have finally got an explanation.
  Musing about Muscle
Jan 21, 2010
I have done a lot of reading and thinking about some of the main issues in building and retaining muscle mass; in view of the epidemic (almost) of sarcopenia (loss of muscle mass) and its adverse effects, this is a very important topic to everyone, not just body builders. Here are some thoughts.
  Muscle Project, Part 2
Jan 19, 2010
Yesterday I began our Muscle Project in earnest.

I weighed 201 in the morning, January 18, 2010.

I am heading back to my long-term weight of 208 with a lot more muscle and a bit less fat.

This lays out my principles.
  How Do Muscles Grow?
Jan 16, 2010
You have to exercise in a way that damages muscle fibers to activate the migration and fusing of the satellite cells with the damaged fibers.
  Human Growth Hormone
Jan 3, 2010
Growth hormone is an antagonist of insulin so injecting it will make one resistant to insulin. Sleep, acute stress, and hunger are the best stimulants because they operate within a network of hormonal and metabolic processes. The cocktail of growth hormone with insulin used by some bodybuilders defies the logic of metabolism and gene expression.
  Steroids and Athletic Performance
Dec 11, 2009

This 2001 article in the Journal of Endocinology reviews a good deal of the research and finds that there is no evidence that steroids improve athletic performance. No one argues that steroids do not increase muscle synthesis and strength, though the strength gains are not much compared to the gains on a similar exercise program.
