The Portugal Endocrinology Association has escalated its warnings about anabolic steroids, branding the unregulated use of these performance-enhancing drugs a public health crisis as cases surge among gym-goers and amateur athletes buying substances online and through smuggling networks.
Why This Matters
• Health fallout is severe: Users face cardiovascular damage, liver disease, infertility, psychiatric disorders including suicide risk, and organ failure.
• Legal crackdown underway: Portugal's regulatory framework is tightening, with new prohibitions on anabolic agents set to take effect in 2026, listing penalties for trafficking under Law 81/2021.
• Influencer culture fuels demand: Social media promoters with no medical credentials often have more reach than scientists, according to the Portuguese Society of Endocrinology, Diabetes and Metabolism (SPEDM).
• Black market thriving: Most purchases happen via internet sellers or contraband, with no quality control or ingredient transparency.
From Elite Doping to Everyday Gyms
What was once the domain of elite athletes seeking a competitive edge has migrated into mainstream fitness culture. Anabolic androgenic steroids (AAS)—synthetic derivatives of testosterone—are now consumed predominantly by recreational gym users, roughly 80% male, chasing aesthetic goals or fighting the visible effects of aging. Studies in Portuguese gyms have found high rates of performance-enhancing substance use among regular attendees, with steroids topping the list.
Paula Freitas, president of SPEDM, told journalists that these compounds have legitimate clinical applications—treating documented testosterone deficiency—but their misuse outside medical supervision carries "very grave impacts on health." The shift from professional sport to amateur bodybuilding has broadened exposure, and Portugal has even emerged as an exporter of illicit anabolics, with police uncovering clandestine labs producing pills and injectables for international distribution.
Estimates suggest 1% to 5% of men in Portugal use anabolic steroids, a figure that climbs substantially among habitual gym-goers. Women remain a minority cohort but are not immune; female users face distinct risks including clitoral hypertrophy, menstrual irregularities, and uterine atrophy.
The Organ-by-Organ Toll
Freitas outlined a catalog of adverse effects that span nearly every bodily system. Psychiatric complications include addiction-like behavior, aggression, depression, and psychosis. Some documented cases have involved increased suicide risk, prompting the SPEDM to stress that "not everything is worth it" in the pursuit of muscle mass.
Cardiovascular damage is particularly insidious: steroids drive hypertension, left ventricular hypertrophy, atherosclerosis, and thrombosis. Acute events—myocardial infarction and pulmonary embolism—have been recorded in otherwise young, fit individuals. Metabolic disturbances are equally concerning, with users experiencing elevated LDL cholesterol, suppressed HDL (the "good" cholesterol), and pro-atherogenic lipid profiles that accelerate vascular disease.
The liver bears a heavy burden: hepatocellular damage, hepatitis, and hepatic adenomas have all been linked to steroid cycles. Kidney function can deteriorate, sometimes culminating in acute renal failure. Even the musculoskeletal system—the very target of steroid use—suffers paradoxically: while bulk increases, the risk of muscle rupture and tendinosis climbs, undermining the structural integrity users seek.
For men, reproductive consequences include reduced or absent sperm production, testicular atrophy, prostate enlargement, impotence, and gynecomastia (breast tissue growth). Steroid use is also associated with prostate cancer. Women face their own endocrine disruptions, complicating fertility and menstrual health.
Contaminated Supply Chains and Legal Blind Spots
Because most anabolic steroids in Portugal are acquired illegally—via online storefronts, Facebook pages, or personal contacts—users have no assurance of purity or accurate labeling. Products may be contaminated, contain undeclared substances, or deliver wildly inconsistent doses, compounding health hazards. Injection practices introduce further infection risks, including HIV and hepatitis.
Portuguese law has historically struggled to address non-sporting steroid commerce. While Law 81/2021 criminalizes trafficking of prohibited substances in sport, enforcement against sales targeting non-athletes has been complex. Nonetheless, the Polícia Judiciária (PJ) has intensified operations. Notable crackdowns include "Operation Underground Pharma" in 2016, which dismantled five clandestine labs and seized 750,000 pills and 50,000 injectable doses, and Portugal's participation in "Operation Pangea XVII," an international sweep that netted millions of illicit pharmaceuticals, including steroids found inside Portuguese prisons.
Regulatory updates are tightening the net. New legal prohibitions on anabolic agents, effective in 2026, align Portugal with the World Anti-Doping Agency's Code. Individuals arrested for trafficking face judicial proceedings, potential asset seizure, and restrictions on contact with sporting organizations.
Influencers vs. Scientists: The Information War
Freitas expressed frustration that gym influencers and self-styled fitness gurus often command greater public trust than credentialed endocrinologists. "Sometimes people listen more quickly to someone without training than to someone who studied, worked, and trained for this," she remarked, calling for scientifically grounded messaging from universities, professional societies, and responsible journalists.
The phenomenon is global. On platforms like TikTok and Instagram, fitness influencers present steroids as a "quick fix" for an ideal physique, frequently glossing over or outright omitting health warnings. This narrative contributes to body dysmorphia, eating disorders, and unrealistic aesthetic expectations among followers, many of whom are adolescents.
Counter-campaigns are emerging. Ireland's Health Products Regulatory Authority launched "Zero Gains," targeting young men with frank information about steroid side effects. The World Anti-Doping Agency's "#NaturalIsEnough" campaign partners with natural-training advocates to promote drug-free fitness. In Portugal, the SPEDM has developed its own awareness initiative and continues efforts to co-publish educational materials on anabolic steroids, aiming to broaden educational reach across Portuguese-speaking populations.
What This Means for Residents
If you train regularly or know someone exploring performance enhancers, understand that anabolic steroids carry irreversible risks—heart disease, psychiatric crises, reproductive failure, and organ damage—that far outweigh short-term aesthetic gains. Medical supervision is non-negotiable if testosterone therapy is genuinely indicated for documented deficiency; self-prescribing via internet vendors is both illegal and dangerous.
Parents and coaches should watch for warning signs: rapid muscle gain, mood swings, aggression, acne clusters, and unexplained purchases. Schools and gyms are being urged to integrate harm-reduction education, offer voluntary cardiovascular and psychological screenings, and partner with health services.
For those already using steroids, harm-reduction resources—such as peer-education programs—can provide safer-use guidance and pathways to cessation. The SPEDM's campaign materials are available to the public, and healthcare providers are trained to manage withdrawal and mitigate complications.
Enforcement and the Road Ahead
Portuguese authorities recognize the scale of the challenge. The PJ continues to dismantle production and distribution networks, but online platforms remain porous, with Facebook pages and unlicensed websites advertising steroids openly. Stronger digital-platform regulation, including content moderation, health disclaimers, and algorithmic demotion of steroid-promotion posts, is under discussion.
Meanwhile, cases of sudden death in young athletes, confirmed by autopsy to involve anabolic steroid use, underscore the urgency. Freitas noted that "cases are appearing more and more," prompting the SPEDM to intensify its public-facing work.
The message from Portugal's endocrinology community is unequivocal: no physique is worth your life. As influencer culture collides with medical reality, residents are being asked to weigh the credibility of their information sources—and to choose science over shortcuts.
