Pharmacological agents: an overview

The term “pharmacological agents” includes both natural and synthetic substances that can affect human physiology by improving performance or accelerating adaptation in sports. In the professional sports world, doping primarily brings to mind anabolic steroids, growth hormone, or erythropoietin (EPO). However, there are also many lesser-known supplements or compounds that are not yet officially included on banned lists, thus legal.

The supplement market is constantly spreading “new generation” blends — from beta-2 agonists to rare plant extracts, sold as “muscle growth promoters” or “endurance enhancers.” However, scientific research sometimes cannot keep up with evaluating their effectiveness or safety, so consumers often rely on manufacturers' promises. Ultimately, regulations (e.g., the World Anti-Doping Agency's WADA code) and scientific studies determine whether certain substances are considered acceptable ergogenic aids or banned doping types.

Not all active substances that improve performance are illegal. In fact, many ergogenic aids are legally sold and used. Many of them have scientific support, but there are just as many or even more dubious, poorly researched novelties.

2.1 Adaptogens and phytochemical compounds

  • Rhodiola (Rhodiola rosea): Studies show reduced fatigue and possibly better endurance, perhaps due to stress hormone regulation. Although not banned in doping context, long-distance athletes show interest.
  • Ashwagandha (Withania somnifera): An adaptogen used in Ayurveda tradition, which may reduce cortisol and help improve endurance. Small studies show it may slightly increase strength and recovery speed.
  • Curcumin (Turmeric): Acts as an anti-inflammatory antioxidant, so it may indirectly help recovery. Athletes use it to reduce muscle soreness.

Since many such adaptogens have not yet been widely studied in long-term placebo-controlled trials, their benefits are often based on small studies or anecdotal evidence.

2.2 Peptides and new molecules

  • SARM (selective androgen receptor modulators): Considered "safer" steroid alternatives, but many SARMs are only research phase compounds. Many are banned by WADA rules or may be classified as doping.
  • GH releasing peptides (GHRP): A group of compounds that stimulate endogenous growth hormone release. Market names arise from doping list risks, so there is much uncertainty about legality.
  • 5-Amino-1MQ: A new research area, possibly affecting metabolism or fat burning, but far from confirmed in clinical practice.

It is known that these molecules can easily fall into a "gray area": unclear legal status or close to doping if WADA decides to classify them as prohibited substances.

2.3 Insulin mimetics and glucose uptake regulators

Products that help the body use glucose more efficiently are insulin mimetics or glucose control enhancing supplements:

  • Better nutrient distribution: Muscles more effectively take up carbohydrates, and fat mass may accumulate less.
  • Stable blood sugar levels: Such compounds help avoid sudden spikes or drops in blood sugar, which is important for endurance and energy.
  • Popular examples: Berberine, alpha-lipoic acid, chromium compounds. There are also newer GDAs (glucose disposal agents), but the scientific basis is often limited.

2.4 Safety, efficacy, and legal status

  • Poor regulation: Many supplements, especially those sold online, are not strictly tested for composition or purity, so adulteration is possible.
  • Lack of research: Long-term effects on hormones, organ function, or drug interactions may be poorly studied.
  • Changing legal status: WADA reviews the list of prohibited substances annually, so something considered "legal" now may be banned in the future if found to have doping-enhancing effects.

3. From doping to legitimate enhancement: ethical boundaries

Between “completely legal supplements” and “banned dopings” there exists a broad grey zone. Although certain substances are allowed, they may raise ethical doubts about “unnatural” advantage or potential health risks.

3.1 Definitions and historical development

  • Doping: Generally, this term describes the use of prohibited substances or methods to artificially enhance athletic performance. Such actions are considered unsafe and unethical.
  • Sports integrity: Numerous scandals (steroids in baseball, EPO in cycling) have damaged public trust and prompted stricter testing.
  • Changes in prohibited lists: WADA updates banned substance lists annually in response to new “workaround” methods or new narcotic compounds.

3.2 The “grey zone” in the supplement market

  • Steroid analogues: Some molecules resembling steroids may not yet be banned but are essentially classified as doping.
  • Mega doses of “legal” supplements: For example, high intake of creatine, caffeine, although not doping, can spark debates about crossing natural limits.
  • Treatment exemptions: If an athlete has a medically diagnosed testosterone deficiency, a therapeutic exemption is granted. But some abuse this system.

3.3 Impact on sports fairness and integrity

In cases where athletes choose advanced or borderline measures, these can distort competition flow and reduce trust. To protect sport:

  • Health protection: Bans help protect athletes from harmful experimental substances.
  • Fostering sportsmanship: The idea of “natural competition” is considered one of the cornerstones of sports values.

4. Science, regulation, and testing protocols

Anti-doping agencies – both international (WADA) and national – closely cooperate with sports federations to prevent doping use. This includes:

  • WADA prohibited substances list: Updated annually to reflect new forms of doping.
  • Analytical methods: Laboratories use mass spectrometry, chromatography, molecular markers to detect prohibited substances or their metabolites.
  • Biological passport: Monitoring an athlete's hematological and hormonal markers over a long period to detect suspicious deviations.

Every new supplement or method sooner or later attracts the attention of doping investigators or regulatory authorities if it provides noticeable unfair advantage or poses a significant health risk.

5. Practical examples: current trends and cases

5.1 Beta-2 agonists in endurance sports

  • Salbutamol, clenbuterol: Legal as asthma medications, but excessive doses can promote fat burning and even slight anabolic effects.
  • Scandals arise when a higher amount is detected in the blood during testing, and the athlete justifies it as “therapeutic” use.

5.2 Collagen or gelatin supplements for joints

  • A natural and legal way to possibly improve tendon and joint condition. Most popular among older individuals or post-injury.
  • Not considered doping, but provides an example where a positive effect can be seen as an “unnatural enhancement.” Still usually acceptable to most athletes.

5.3 “Blood flow restriction” (BFR) training + “blood boosters”

  • BFR: A mechanical method where blood flow through veins is restricted using special sleeves. Allows low-weight training to induce hypertrophy.
  • “Blood booster” supplements: For example, certain nitrates or even indirect EPO mimetics attract the attention of doping authorities.

6. Risk management and informed use

Those seeking legal ergogenic aids must consider:

  • Review of anti-doping lists: It is necessary to constantly check whether the substance used is not prohibited. Some “legit” supplements may contain doping impurities.
  • Quality certifications: NSF Certified for Sport, Informed-Sport, or others ensure the product is free of banned substances and properly labeled.
  • Consultations with specialists: A doctor, pharmacologist, or sports nutrition specialist can help understand possible interactions with existing medications and risks.
  • Caution regarding “spiking”: Some supplement manufacturers illegally add stronger active substances to speed up the effect. This can mean doping or health risks.
  1. Combinations of nootropics and ergogenic aids: Effects on both the brain and physical endurance. Possible “dual-effect” supplements that improve focus and strength.
  2. Even greater personalization: Genetic tests, biomarkers, and daily sensor data can be combined to automatically adjust supplement choices.
  3. Monitoring of biological markers and microdosing: Real-time apps could indicate when it's time to consume some “legal” substance, reacting to signs of fatigue.
  4. Increasing regulation: As new compounds emerge, doping control and medical monitoring will evolve to remain effective.

8. Practical tips for athletes and enthusiasts

  1. Do your homework: Before taking a new supplement, check studies, manufacturer reputation, and reviews.
  2. Track effects: Monitor your well-being, blood markers, or training data to evaluate the real benefits of supplements.
  3. Basics first: Sleep, nutritional balance, and a proper training plan remain the most important, even when using advanced agents.
  4. Avoid ambiguous substances: If you are a professional athlete, it is unwise to risk using little-known compounds that may be banned.
  5. Consult: When in doubt, seek certified nutrition or sports medicine professionals to objectively assess risks and opportunities.

Conclusions

From newly discovered ergogenic supplements promising muscle growth, increased endurance, or faster recovery, to ongoing debates about doping in sports – pharmacological agents occupy a controversial yet very interesting place in athletics and fitness. Legal, scientifically supported compounds (e.g., adaptogens, some insulin mimetics, or natural peptides) demonstrate how science helps improve performance while avoiding health risks. However, the line between legal supplements and doping often remains blurred – doping regulatory bodies monitor every innovation, striving to prevent unfair advantage or long-term health damage.

Perhaps nothing can replace sustainable work – consistent training, balanced nutrition, and full rest – to achieve long-term results. However, properly selected pharmacological agents can sometimes accelerate recovery, help address certain bodily deficiencies, or manage health conditions. It is essential to carefully evaluate scientific research, prohibited doping lists, and moral issues to ensure these agents do not contradict the spirit of sport or pose a danger to the user's health. By combining a cautious approach, reliable data, and respectful adherence to sports rules, it is possible to responsibly benefit from modern scientific advances while maintaining sportsmanship.
