Athletes: How to Increase IGF-1

igflr3 football playerAt mindandmuscle.com, we always play on the side of caution.  In an industry where people make money at the expense of the customer’s health and well-being, we think it is only humane to be the exception.  That being said, we are a little skeptical about all the research peptide companies popping up.  I’m sure many of them are legitimate, but I’ve been in the industry long enough to know that many of them are not.  Also, I spent a good amount of time in China.  Trust me, nothing is as it seems in China. That being said, many athletes and body builders alike are turning to these growth hormone releasing and IGF-1 boosting peptides with tremendous success.  It is no secret that some consider the insulin acting IGF-1 the holy grail of muscle building.  However, one cannot just inject pompous amounts of synthetic IGF-1 LR3 and expect to get continued benefits with minimal diminishing returns.  Long story short, after a few weeks of exogenous synthetic IGF-1 supplementation the body’s receptors are filled and the excess IGF-1 doesn’t get utilized by the body.  Similar to testosterone cycles and comparing “total testosterone” and “free testosterone.”  One of the problems with GHRP and IGF peptides is in drug testing.  If you are a college athlete who gets tested for banned substances, HGH, and steroids, you will most likely come up dirty for using these peptides.  Don’t get me wrong, it is still your choice as to whether or not you want to throw your career out the window or not.  That seems to be the trend these days anyway. This brings us to the question of the hour.  How can we legally maximize the body’s own production of IGF-1 while staying within equilibrium and therefore maximizing long term benefits of the hormone?  Got milk?

bicep curlIn the US, people drink more soda pop than milk.  I think we can all agree that milk is the healthier of the two.  But besides the protein edge that milk has on soft drinks, what about hormone levels?  Researchers from the University of Copenhagen gathered together 11 healthy men, ages 22-29, to drink 2.5 liters of coke per day for ten straight days.  After the ten-day course, they drank 2.5 liters of milk each day for ten more days.  Many fattening and sugary foods raise insulin levels and insulin resistance.  Milk and coke both scored high on that test.  That can be a good or bad thing depending on how you look at it and your timing of ingestion.  Below you can see how both the milk, and the coke, effected insulin and glucose metabolism in the subjects (Figure 1).

I am not as concerned about that as I am with IGF-1 levels.  The levels of the extremely anabolic hormone, IGF-1, decrease during the ten days of coke ingestion (Figure 2).

Like I was saying before, not all IGF-1 is active in the body.  Some of it is bound to the IGFBP3 protein, which makes it the most active.  And although the P levels were a bit to high to be statistically significant, drinking milk did increase the IGFBP3 production as well (Figure 3).  Here you have milk helping your liver pump out more IGF-1 while simultaneously stimulating IGFBP3 production.  This equals more active IGF-1 in the body inducing anabolic effects.

So we can definitely say that bodybuilders, athletes, and kids are better off drinking milk than coke.  That’s obvious. IGF-1 is used in the body to recover after training and build muscle by stimulating tissue repair and growth.  I am not saying that drinking 2.5 liters of milk is healthy in the long term, and neither are the researchers in this study.  I do find it interesting, however, that milk can have that type of effect on IGF-1 in only ten days.  ***Adding to this weeks grocery list, “Buy a cow.”  Cheers.
