Muscle Minds 191 Does L-Carnitine Really Upregulate Androgen Receptors? | Study Breakdown
2026/09/19 | 1h 17 mins.Does L-carnitine actually increase androgen receptor content—or has social media exaggerated what the research shows?
In this episode of Muscle Minds, Scott Stevenson presents a detailed breakdown of the Kraemer L-carnitine study behind this popular bodybuilding claim. Scott Stevenson and Scott McNally examine what the researchers actually measured, how the study was designed, what the results showed and the limitations that are often left out of social-media explanations.
The evidence does not support the claim that L-carnitine upregulates androgen receptor content. We also discuss why this proposed effect would matter to bodybuilders, the questions the study leaves unanswered and what can—and cannot—be concluded from its results.

[http://www.supplementsource.ca](http://www.supplementsource.ca)- Is the post-diet rebound really where bodybuilders make some of their best gains, or did the growth actually happen during prep and only become visible once calories come back up and the physique fills out?
Skip Hill, Andrew Berry and Scott McNally kick off Blood Sweat & Gear with a deep dive into the “magic” of the rebound. The guys break down what actually happens after a hard diet, how they approach rebound phases with clients, how quickly bodyweight should come back up, and the factors that determine whether someone has a productive rebound or just gets fat.
They also look at real-world rebound examples and discuss what needs to be in place before pushing the enhanced side of a rebound.
Later, the conversation gets into Tren E night sweats going into a show, injectable oral steroids, testosterone levels on cycle, DNP and methyl tren rankings, boldenone acetate, recovery methods, physique critiques and more.

Blowout deals on top supplement brands
https://www.supplementsource.ca- Scott McNally and Dave Crosland are back with a slightly different start to Drugs n Stuff. Before getting into the usual steroid talk, Scott surprises Dave with a gift he definitely wasn’t expecting.
Then it’s into Steroids in the News with a recent steroid bust that affected a lot of people in the community, including a breakdown of the compounds involved. From there, Scott and Dave get into listener questions and stories — including someone claiming to have used 600mg of oral steroids per day, first-cycle Tren, low-dose EQ for estrogen control, some insane bulking experiences, Deca + EQ vs. Test + Deca, whether high natural testosterone changes cycle design, alternatives to Primo, low-dose Deca with TRT, teenage steroid use and brain development, and the growing debate around “neurotoxic” steroids.

https://think-big.printify.me/products - What’s the craziest thing you’ve ever done to bulk? Dave Crosland and Scott McNally look back at the extremes bodybuilders will go to in the pursuit of size — and how distorted your perception of your own body can become along the way.
Then we get into your questions on a 15-year-old using Test, Tren and Mast, whether peptides are getting out of hand, post-cycle sexual performance, choosing a second compound with testosterone, whether different steroids actually build different-looking physiques, gaining muscle after massive weight loss, GLP-1s and muscle growth, testosterone-to-estrogen ratios, Arimidex, ephedrine and more.
