A New ‘Species’ is Born: Species Nutrition Supplements In Review

By Leigh Penman

Species Nutrition aim to create products that contain only the highest quality ingredients and present them in specific formulas that have real science and research behind them. You are not going to find complex diagrams, graphs and futuristic explosions of plasma illustrating their effectiveness. Facts not fantasy are what the rapidly growing (no pun intended) range of Species products depend on to illustrate their effectiveness. Founded by two of bodybuilding’s greatest minds (and bodies) Dave Palumbo and Colette Nelson you can bet that Species Nutrition is one company you are going to be hearing a lot more of in the future. One of their best selling products is currently the aromataze inhibiter/testosterone booster, ‘Testolyze’. So what better way to begin this look at the Species product range than by grabbing a bottle and putting it under the supplement microscope?


Testolyze separates itself from the proliferation of anti-estrogen/testosterone boosting supplements on the market by virtue of the attention to detail given to its formula. It contains the ever-popular 6-OXO which is known to effectively increase testosterone levels by blocking the action of the aromataze enzyme. The aromataze enzyme is the primary enzyme involved in the conversion of testosterone to estrogen. As all bodybuilders know, too much estrogen leads not only to water retention and fat deposition but can also trigger gynecomastia and the possible shutdown of natural testosterone production. The traditional cure for this situation has been to use estrogen receptor antagonists such as Nolvadex or Clomid which act like pigeons in the nest of estrogen receptor sites (i.e. they step in and take over the site leaving estrogen homeless). In recent years aromataze inhibiting drugs such as Arimadex and Proviron have also become popular. These drugs simply act to eliminate estrogen altogether which, in theory, sounds great but in practice can spell disaster for the hard training athlete.

This is due to the fact that the body needs a certain amount of estrogen to be present in order to facilitate muscle gains, maintain healthy cholesterol levels and prevent libido going down the lane of lost souls. Add to this the fact that Proviron is the closest thing to orally active DHT (Dihydrotestosterone) – the main culprit in male pattern baldness – and you do not have a pretty picture.

So where does a product like TESTOLYZE fit into the picture? Well, Testolyze is spearheading a new generation of aromataze blockers. The unique formula combines 6OXO (a clinically tested and proven aromataze blocker) with the herb Saw Palmetto.
Saw Palmetto has been used for many years as a natural inhibitor of the enzyme 5-alpha-reductase. This enzyme converts testosterone to DHT and an excess of DHT in hair tissue leads to hair thinning in men and women. It has also been linked to prostate enlargement in men.

Put simply, what this means is that Testolyze facilitates the growth of muscle tissue via the creation of the perfect hormonal climate within the body. It eliminates excess estrogen without annihilating it completely and prevents the build-up of DHT and all the nasty side effects it presents. It doesn’t take a rocket scientist to figure out how valuable this scenario is to the athlete!


Testolyze certainly leads the pack of over-the-counter testosterone enhancing anti-aromataze products currently on the market.

Leigh Penman, in addition to be a staff writer at MuscleSport Mag, has been writing for bodybuilding magazines, websites and nutritional supplement companies since 1985. Whilst residing in the UK, she earned the reputation of being one of the top female writers in bodybuilding-related media. Her credits included being a contributing editor on all the magazines in production as well as filling the shoes of Ladies Editor and Showbiz Editor on two publications (the later being on Arnold’s sanctioned magazine, ‘Bodypower’). During this time she also competed successfully on four occasions (placing in the top four in all contests).

Relocating to New York in the late 1990s she focused her writing attention to crystal healing techniques and metaphysics – however, she still maintained a five day workout schedule during this time and gained her personal training certificate.

Having also studied pharmacology in relation to sports performance, her writing began taking her in that direction until the present day which sees her embarking on a return to the magazine world, as well as extending her web-related work in the bodybuilding and fitness field.

Leigh has been working out for close to thirty years so she is clearly a writer who ‘walks her talk.’
