Is DK Metcalf on Steroids? NFL Star Genetics Analyzed
The NFL Drug Testing Policy and Metcalf
The NFL enforces a strict Policy on Performance-Enhancing Substances. Under this collective bargaining agreement, players are subject to random, unannounced drug testing throughout both the season and the offseason.
If DK Metcalf were using anabolic steroids, masking agents, or other banned substances, he would be subjected to the same testing protocols that have caught and suspended numerous other NFL players. Metcalf has a completely clean testing record.
The “Random” Test Phenomenon
In the NFL, the timing of “random” drug tests sometimes raises eyebrows. Metcalf has publicly shared instances where he was selected for drug testing immediately following viral displays of athleticism. For example, in February 2023, just hours after a video of him making a seemingly impossible, high-jumping one-handed catch went viral on social media (and following his MVP performance at the NBA All-Star Celebrity Game), the NFL issued him a notice for a random drug test.
While the league maintains tests are generated randomly by a computer system, players often joke about “random” tests following extraordinary athletic feats. Metcalf passed the test without issue.

Debunking the 1.6% Body Fat Myth
Much of the skepticism surrounding Metcalf’s natural status stems from the 2019 NFL Combine. A report circulated widely that Metcalf measured at a staggering 1.6% body fat while weighing 228 pounds at 6’3″.
This number fueled intense steroid speculation. However, sports medicine professionals quickly pointed out that the measurement was biologically impossible:
- Essential fat: The human body requires approximately 3-5% essential body fat just for basic organ function and central nervous system health.
- Survival limits: Professional bodybuilders step on stage at absolute physiological extremes of 3-4% body fat, feeling miserable and near collapse. A person cannot perform elite athletic combine drills at 1.6%.
- The reality: The 1.6% figure was the result of a flaw in the testing methodology (likely calipers or a Bod Pod reading error). Realistic estimates place Metcalf’s in-season body fat closer to 6–8%—which is remarkably lean for his size, but physiologically possible for a genetic outlier without drugs.
The Role of Elite Genetics
In analyzing Metcalf’s physique, fitness experts point to his genetic baseline. He comes from a highly athletic family (his father, Terrence Metcalf, was an NFL offensive lineman). Photographs of DK Metcalf in high school and early college show he already possessed a massive, highly muscled frame long before reaching the NFL.
Diet and Training
Ironically, Metcalf has admitted that his diet is not the strict, calculated regimen one might expect. In interviews, he has casually mentioned eating candy (like Skittles and gummy bears) and drinking coffee as staples of his daily routine, eating only one main meal a day. This unconventional diet further points to his metabolism and genetics doing the heavy lifting regarding his low body fat, rather than a biochemically engineered steroid cutting cycle.
Frequently Asked Questions
No. DK Metcalf has never failed a drug test in the NFL and has never been suspended for using performance-enhancing substances.
No. Medical and fitness experts agree that 1.6% body fat is a physiological impossibility for a functioning athlete. The reading at the 2019 Combine was an equipment or methodology error. His actual body fat is likely around 6-8%.
Metcalf is subject to the NFL’s random drug testing policy. He has received test notices shortly after viral athletic performances, which the league maintains is purely coincidental computer randomization.
Metcalf is listed at 6 foot 4 inches and typically plays at a weight of around 235 pounds, carrying immense muscle mass with very low body fat.
For the average person? No. For someone with elite, one-in-a-million NFL genetics, decades of training, and world-class physical therapy and nutrition? Yes. His physique is the result of extreme genetic advantages.
