Is GREG DOUCETTE Wrong About Testosterone?

Before I get started with this video, I ask that you all kindly head over and follow me on Instagram @veganberserker, which I’ve recently begun posting to.

It’s feeling kinda lonely over there at the moment, so why not help me build a following?

I will be actively posting physique updates, motivational content, food porn, travel photos and other odds and ends as time moves forward.

Recently, rising YouTuber Greg Doucette released a video titled “Train Softer than Last time”, where he responded to Dr. Sam Robbins.

Now, I have no clue who in the hell Dr. Sam Robbins is, but I do regularly tune into Greg’s channel as I find his content to often be informative and entertaining. So, for any of Greg’s followers who’ve found this video and think it’s going to be full of smack talk… think again.

In this video I want to discuss one specific concept that Greg had addressed in his; it is something that I had covered all the way back in July 2016, but I feel is important to reiterate as it is something many people do not seem to know nor understand; something which might even lead some folks into being swindled by the supplement industry.

This video is all about testosterone levels and their impact on muscle growth.

Let me start by playing a clip from Greg’s video.


Greg is, indeed, correct about this, at least going by the body of data we have on the topic.

Research has shown that so long as a man’s testosterone levels fall within the physiological normal range, muscle growth and strength increases do not appear to vary much at all. In fact, it appears that a man would need to exceed the physiological normal range by 20-30% (for ex., by taking steroid) in order to experience a significant increase in his ability to build muscle.

And for the unaware, the healthy testosterone range for men is 270 to 1,070 nanograms per deciliter; so, it is rather broad.

The point I am trying to make is that a man at the top-end of that healthy range does not appear to possess any greater ability to acquire muscle tissue from weight training than a man at the bottom-end of the healthy range; even if they’re, say, 700 nanograms per deciliter apart in natural production. So, I fully agree with Greg.

In other words, those ultra-pricey testosterone boosters you’ll find at your local GNC… yeah, they won’t be doing one hot shit for your muscle growth; so, save yourself the hard-earned money.

Now, with that being said, I would like to add something that Greg did not address that may be of interest to some of you… depending on your goals, that is.

While possessing higher testosterone levels within the healthy range may not help you build more muscle, possessing higher levels does appear to have a significant impact on body fat storage.

According to a 2004 paper, fat mass was 36% higher among men with testosterone levels at 300 nanograms per deciliter, which would be considered low-normal, compared to men with testosterone levels at 600 nanograms per deciliter, which would be considered about average.

So, maybe a bottle of Longjack or fenugreek extract isn’t going to help you build more muscle, but it might improve your waistline if your diet and exercise program are in-check.

Anyway, leave your thoughts and comments below.
