You pick the sport and enter your body weight. You get a supplement kit for 8 weeks, a schedule with the daily dose of every product, and the reason each one is in the kit.
The kit is built from two answers: discipline and body weight. It comes with a schedule of what to take on which day, and the reasoning behind every product in the kit.
Protein, creatine, omega-3 and electrolytes calculated from body weight following scientific guidelines: AIS, ISSN, IOC. A change in weight instantly recalculates the whole system.
Every batch is tested at the independent J.S. Hamilton laboratory, and the reports are attached to the product pages. The formula does not change until the evidence does.
The 8-Week System is the shared base. The configurator on each sport page adds the rest of the system: it matches a kit to the answers and calculates a daily schedule from body weight, with a price per day of supplementation.
Every discipline page includes a dose planner based on body weight and a schedule for 8 weeks of preparation. The list of disciplines is growing.
Four products taken every day, on training days and rest days, regardless of discipline. Kits for a chosen discipline are on its page.

Working with athletes kept showing the same picture: a shelf full of jars and no answer to which of them change the result.
So we started from the other end. First the scientific evidence and the AIS classification, then the dose, then the product. What stayed is what has confirmed effects in competitive sport. The rest was dropped from the lineup.
Formulas, doses and safety of use are overseen by a physician, a sports medicine specialist and board member who works with competitive athletes every day.

THE SCIENCE BEHIND THE BUNDLE
The daily foundation, whatever the discipline: four products with the strongest data for people who train regularly. Below: what each one does, its AIS group, and the study the dose comes from.
The best-documented supplement in the sports literature. Combined with training, it increases gains in strength and lean mass and supports repeated bursts of up to 30 seconds. Maintenance dose of 0.03 g per kilogram, full saturation after 3-4 weeks. Powder or capsules, the same molecule.
IN STUDIES
Safety data for up to 5 years of use (Kreider et al., ISSN 2017). +5.3% in the bench press, meta-analysis of 53 RCTs (Lanhers et al. 2017).
Protein needs with regular training run 1.4-2.0 g per kilogram daily, hard to cover from food alone without extra fat. A 30 g serving delivers 26 g of protein and 2.8 g of leucine, above the 2-3 g threshold that triggers muscle protein synthesis. Five ingredients in the formula.
IN STUDIES
Meta-analysis of 49 studies and 1863 people: +2.5 kg of 1RM strength and +0.3 kg of lean mass over training alone (Morton et al. 2018).
The WHO recommendation is two servings of oily fish weekly; in the Polish diet, few people meet it. Two capsules cover the 1-2 g range of EPA and DHA recommended for active people. TOTOX 10.5, less than half the GOED limit. Effects show after 6-8 weeks, the timescale of this set.
IN STUDIES
ISSN 2025 position stand: omega-3 supports recovery and strength development with resistance training (Jäger et al., ISSN 2025). Lower post-exercise muscle damage markers in 3 of 4 studies (Fernández-Lázaro et al. 2024).
Magnesium, B vitamins and folate contribute to normal energy-yielding metabolism and the reduction of tiredness and fatigue. Zinc and vitamins A and B6 support immunity. The formula contains no iron or calcium, which at higher doses limit magnesium and zinc absorption. 2 capsules daily with a meal containing fat.
IN STUDIES
IOC: athletes are at higher risk of micronutrient deficiencies than the general population (Maughan et al., IOC 2018). Systematic review: 300-500 mg of magnesium daily supports jump performance, 1RM and fatigue resistance (Heffernan et al. 2019).

WHY THERE IS NO SINGLE FACE HERE
AUSTRALIAN INSTITUTE OF SPORT · SINCE 2000 · Official classification: ausport.gov.au →
ATHLECOR is not affiliated with the Australian Institute of Sport or the Australian Sports Commission.
No single person decides the formulas here. Formulas and doses follow the Australian Institute of Sport classification, run since 2000 and updated regularly by an expert committee against three questions: is it safe, is it permitted in sport, is there evidence that it works.
Supplement trends change every season. The classification changes only when the evidence changes, which is why ATHLECOR formulas stay the same.
Research is one side. Practice is the other: scientific oversight is led by a physician, an orthopedics specialist, formerly the doctor of a professional cycling team, since 2025 on the medical staff of a Polish national team in a team sport (Nations League gold in 2025 and 2026); he is an active cyclist himself. The products are made for everyone who trains and proven at the highest level. Team and expert oversight →

MEET THE TEAM AND THE SCIENTIFIC OVERSIGHT →ATHLECOR grew out of two perspectives: sports medicine and the practice of an athlete-entrepreneur. The team is described on the About page.
The purity and safety of every batch is tested by the independent, accredited J.S. Hamilton laboratory. Full reports with the batch number are published on every product page.
Raw materials are tested at the Institute of Agricultural and Food Biotechnology (IBPRS).
Standardization and active compound content are verified by independent testing at Lodz University of Technology.
The Australian Institute of Sport has run a public classification of supplements by strength of evidence since 2000, adopted as the industry standard for 25 years. Group A: effectiveness and safety confirmed in studies on athletes, with an established dose. Group B: evidence of benefits within a system of use (dose, timing, duration). ATHLECOR products that affect performance are in group A or B, and the classification is public, so every formulation decision can be checked at the source.
