what it claims

Some supplements (creatine, whey, caffeine, ashwagandha) are genuinely effective and useful, while others (collagen, EAA/BCAA, glutamine, testosterone boosters, fat burners) are largely useless, ineffective, or overrated for muscle gain and performance.

Layne Norton relies on a solid foundation: the superiority of creatine, whey, and caffeine is widely documented by numerous meta-analyses.

Layne Norton relies on a solid foundation: the superiority of creatine, whey, and caffeine is widely documented by numerous meta-analyses. Regarding EAA/BCAA, the literature, specifically a cited study (PMID: 24620007), effectively confirms that they provide no additional benefit if total protein intake is sufficient. On collagen, he highlights an important limitation: its bioavailability and amino acid profile make it inferior for muscle protein synthesis compared to complete proteins, an observation supported by controlled trials. His skepticism regarding testosterone boosters and fat burners also reflects the current scientific consensus, which struggles to demonstrate significant effects in healthy individuals. Ashwagandha is a more nuanced point: although studies show benefits for stress and strength (often cited in RCTs), the robustness of the evidence regarding muscle gain remains subject to debate compared to nutritional pillars. The analysis is overall very faithful to current data, avoiding marketing promises in favor of physiology.

There is no single optimal repetition range for muscle growth (hypertrophy); development is similar across a broad spectrum (3 to 30 repetitions) as long as effort is close to failure.

If you are not losing weight while in a caloric deficit, it is likely because you are massively underestimating hidden calories (oils/butters) in restaurant meals; it is therefore recommended to overestimate the calories in your dishes by 30 to 50% or to adopt strict meal planning strategies.

Hunger is the most powerful adaptation during a diet, surpassing even metabolic slowing, because the body biologically prioritizes the search for food as soon as energy reserves decrease.

Prepare breakfast sandwiches made with eggs, vegetables, and protein in advance (meal prep) and freeze them to have a quick, satiating, and energizing meal for busy mornings.

Vitamin C is a well-documented, essential cofactor for collagen synthesis (it activates the enzymes that stabilize its structure); gelatin supplies the basic amino acids (glycine, proline, hydroxyproline). The biochemistry behind this recipe holds up — what isn't directly measured is the visible effect on 'skin glow.'

Sleep isn't dead time for your muscles — muscle protein synthesis keeps repairing and rebuilding tissue damaged during the day while you're out.

Other advice in the Register that leans on the same research.

For building muscle, only two supplements have solid, consistent evidence — creatine monohydrate (3-5g/day) and protein powder if your food intake is already falling short. Everything else — turkesterone, HMB, testosterone boosters, mass gainers — is either ineffective or only situational, and the placebo effect (believing it works) sometimes outweighs the compound itself.

Siim Land proposes a list of 15 dietary supplements he considers beneficial for human health, including substances such as creatine, omega-3s, ashwagandha, and various vitamins and amino acids.

The most popular dietary supplements for muscle gain or fat loss (fat burners, testosterone boosters, BCAAs, HMB, and steroid alternatives) have an extremely low, or even non-existent, cost-effectiveness ratio.
