Sławomir Ambroziak

Sławomir AmbroziakHe’s a man who has much to say about supplementation and legal pharmacological sport enhancement. He’s a former athlete, pharmacist, coach and judge of strength sports, bodybuilding and bodyfitness. In 1993 he has co-founded a sport pharmacy Medsport – the first medical retail shop where top professionals are engaged in and deal with sport performance enhancement. The pharmacy has been opened on initiative of Polish Society of Sports Medicine as well as Central Sports Medicine Centre. Since that time he popularises information about dietary supplements, their ingredients, effect, use and influence on healh and performance. He has published more than 1000 articles on sport enhancement. It is very difficult to find at least one nationwide scoped magazine on health or sport that haven’t had the honour of publishing his articles. In the space of years his works have been published in Sports Medicine (Medycyna Sportowa), Olympian (Olimpijczyk), Track and Field Athlete (Lekkoatleta), Iron Pumper (Paker), Muscle Fitness, Muscle, Iron, Flex, Lady Fitness, Shape, Bodybuilding (Kulturystyka), Form (Forma) and many others. He has been a consultant and a very popular guest in specialist press (ex. „Drugs in Poland” [Lek w Polsce], „Diabetic” [Diabetyk]) as well as health press („My Health” [Moje Zdrowie], „Medicine for You” [Medycyna dla Ciebie], „Super Figure” [Super Linia] etc.). He’s an author of monograph on L-carnitine. For over 10 years he has edited an extremely popular column in Sport Roundup magazine („Przegląd Sportowy”) called Sport Pharmacy; what is more, for over 7 years he has been one of the most widely read authors of „Bodybuilding and Fitness. Sport for Everybody” magazine („Kulturystyka i Fitness Sport dla Wszystkich”). Now, he’s a member of a team of experts in an exclusive high volume magazine on sport and health – Perfect Body. Every article published there is packed with substantial scientific value and perfectly compliments information published on this website.

Capsaicin helps seniors and athletes

Autor: Sławomir Ambroziak

Keywords: capsaicin, nitric oxide, peroxynitrite, arginine, vanilloids, mTOR kinase, TRPV1 vanilloid receptor, overload induced muscle hypertrophy, sarcopenia, cachexia, atrophy.

Although our muscles seem to be a well-known and thoroughly studied tissue, in fact they have a whole bunch of hidden secrets. We still do not know, for example, how to cure most of the muscle diseases and how to prevent muscle atrophy associated with immobilization or denervation. Available in pharmacies popular anabolic drugs that regenerate muscles do not fully meet our expectations in treatment of cachexia and sarcopenia – loss of muscle mass related to age or to some chronic wasting diseases such as cancer, diabetes or AIDS. And because today we know that the proper condition of our muscle tissue is of extreme importance to both slowing down the aging processes of the body and successfully recovering from a variety of serious diseases, therefore scientists are constantly struggling to understand and explain still poorly known mechanisms of muscle development and regeneration. więcej…

Aromatase in the dock

Author: Sławomir Ambroziak
Keywords: aromatase, aromatase inhibitors, estrogen, testosterone, cortisol, polyphenols, fatty acids, steroids, triterpenoids.

Gynecomastia – feminine look of the male breast, lipomastia – the excessive accumulation of fat around the nipples, breast cancer, prostate hypertrophy and cancer – all of these problems can have a common reason which is called: aromatase. więcej…

Cortisol – catabolic or anabolic?

Cortisol – catabolic or anabolic?

By Sławomir Ambroziak

Keywords: cortisol, testosterone, catabolism, anabolism, receptors, transcription factors, coregulators, coactivators, corepressors, selective steroid receptor modulators, SERMs, SARMs, SVDRM, SGRM.

If testosterone is probably the most popular hormone amongst athletes, then cortisol – the most hated.

We all know that testosterone is an anabolic hormone that is one that stimulates muscle protein accumulation processes and thus contributes to muscle strength development and weight gain. On the contrary, cortisol is called a catabolic hormone that acts contrary to testosterone, interfering any positive effect of the latter on our muscles. więcej…

Resveratrol contributes to body weight and total body fat loss and increases muscle mass in active middle-aged man

Resveratrol contributes to body weight and total body fat loss and increases muscle mass in active middle-aged man

By Sławomir Ambroziak
Keywords: resveratrol, body weight, total body fat, muscle mass, arm circumference, waist circumference.


It has been demonstrated in several studies on resveratrol use in animals and isolated tissues that resveratrol is likely to promote fat loss as well as muscle tissue development in humans. Such activities of resveratrol are extremely attractive for many sports athletes, thus commercial supplements containing resveratrol have appeared on the market recently. They are precisely targeted at athletes. Unfortuntely, currently there is no research proving the lipolytic and anabolic activity of this supplement that has been conducted on physically active subjects or athletes. In order to obtain a general confirmation of the possible beneficial effect of resveratrol on body composition, we decided to do a consumer short-term trial involving a physically active middle-aged man. więcej…


Keywords: DHT, testosterone, 5 alpha-reductase, aromatase, estradiol, 3 alpha HSD, 3 beta HSD, 3 alpha adiol, 3 beta adiol, isoflavones, androgenic receptors, alpha estrogen receptors, beta estrogen receptors.

Dihydrotestosterone (DHT) is a metabolite of testosterone – a major anabolic hormone that builds our muscles. The more testosterone in the body, the greater level of DHT. For years it has been believed that DHT has no effect on the muscles and is only responsible for the adverse effects of testosterone – seborrhoea, hair loss and prostate hypertrophy.

However, the results of new research and opinions of athletes seem to contradict those old beliefs… How would you explain the fact that the use of testosterone in conjunction with medications or supplements that inhibit its conversion to DHT gives weaker anabolic effects than the ‚pure testosterone treatment’, without similar extra supplementation…?

Does it mean there’s no alternative here? Do high testosterone level and superb muscles have to be associated with acne, male pattern baldness and problems with urinating?


Taurine – rattling bull therapy

Key words: taurine, glutamine, creatine, carnitine, insulin, somatotropin, sertonin, GABA, anabolic, anticatabolic, psychostymulant, thermogenic.

It was discovered by Tiedemann and Gmelin in 1827 in ox bile. Its name derives from Latin ‘taurinus” that means ‘relating to or resembling a bull’.
It’s an abundant amino acid in the body; however, it’s different to amino acids that build our muscle proteins. Its acid group does not come from organic carboxylic acid, but from inorganic sulphuric acid. Therefore, it does not build any proteins, only simple micropeptides at best. Amino acids that do not build proteins are called non-proteinogenic amino acids. They are not less important from proteinogenic ones, see creatine and carnitine. więcej…

Taurine burns fat!

Key words: taurine, glucose, insulin, adrenaline, noradrenaline, fatty acids, adipose tissue, cysteine dioxygenase, CDO, PPAR, UCP, thermogenesis

Japanese scientists have just discovered an unknown face of taurine. This amino acid is well-known to bodybuilders as it acts as an anabolic and anticatabolic agent; but now it has occurred that it also intensively stimulates fat burning processes in subcutaneous adipose tissue and facilitates its reduction. It is worth mentioning that Japanese have particularly took a fancy of taurine as most of the information on this amino acid comes from the Cherry-Blossom Land. więcej…
