Several studies have found that even the addition of a multivitamin to the diet of people did not increase the levels of zinc, magnesium and other minerals, while the serum vitamin levels did go up.

The authors theorized this was due to competition of the minerals in the multivitamin.

So, it would appear that different minerals need to be taken at different times and taking them altogether may not be an optimal, or even effective, strategy for increasing levels of these minerals in tissues.

The fourth contention regarding the forms of minerals is a bit more un- proven, in this writer’s view. Though it is well known that there is a wide range of absorption between different forms of nutrients, especially miner- als, so the concept is not far fetched.

The idea behind these supplements is to supply highly absorbable forms of non-competing minerals (in this case zinc and mag) known to be essential for the optimal production of anabolic hormones. Though a variety of com- panies are now selling this product, the letters ZMA appear in the name or on the bottle only if the product is using the patented ingredients.

We note the research done by a Dr.

Brilla at Western Washington University. Dr. Brilla found the addition of 30 mg of zinc monomethionine-aspartate and 450 mg of magnesium aspartate (the forms used in ZMA) daily to foot- ball players had a 32 percent increase in total testosterone, a 3.6 percent increase in IGF-1, and improvements in strength levels.

So, at this time About Steroid Cycles and Legal Stero, the general contention of the companies now selling this new zinc and magnesium based products appears to hold water, though future research needs to elucidate these findings further.

So it would ap- pear that different minerals need to be taken at different times and taking them together may not be an optimal, or even effective, strategy for in- creasing levels of these minerals in


What does the real world have to say?

Some have reported seeing modest gains in strength and performance with ZMA, although perhaps for an additional reason: ZMA is taken at bed- time, on an empty stomach. Taken this way, many insist that it helps them spematon instructions for use reviews price get a good night’s sleep, and that reason alone is enough for many people to continue taking it.


With regard to the relationship between essential minerals steroids for sale and testoster- one, one important caveat to remember with ZMA (or similar product) is that it will only work if there is a deficiency to correct. Supplementation will not increase levels of anabolic hormones where no deficiency in these minerals exists.

ZMA is not magic, by any stretch.

As an aid to sleep, however, ZMA appears to be effective and useful. So, I give this supplement a thumbs up, understanding the caveat above.

The potentially negative effect of the “female” hormone estrogen is a con- stant concern for athletes. Increased estrogen may lead to increases in body fat and other maladies athletes want to avoid (gyno, etc.) and many supplement companies have attempted to capitalize on this concern over excessive estrogen levels.

For example, some research suggests that supplements such as andro- stenedione, and a few of the other “andros,” may increase estrogen levels by converting to estradiol (a powerful estrogen).

Victor Conte lays out Dwain Chambers’s doping/steroid protocol; Does Blue Cross/Blue Shield cover this?

Androgens such as tes- tosterone and androstenedione convert to estradiol via an enzyme called “aromatase.” Drugs or natural compounds that can block this enzyme are therefore called “anti-aromatase” agents.

Basically, there are two ways to affect estrogen. You can block the recep- tor site, or you can inhibit the enzyme (i.e. aromatase) that converts “male” hormones into “female” hormones (i.e. estrogens).

When a molecule fits into the receptor but does not send an estrogenic signal, it is called an “antagonist” meaning it prevents or “blocks” estrogen from getting to the receptor, but does not, in itself, act as an estrogen.

Hence the term “estrogen blocker.”

When something can lock into the receptor and does act as an estrogen, that is, activates the receptor to one degree or another, it’s called an “ago- nist.” So, an antagonist fits into a receptor (thus blocking something else from occupying that receptor) but does not activate the receptor and an agonist fits into the receptor in question (in this case an estrogen receptor) and does activate the receptor to one degree or another.

This is exactly how the drug Tamoxifen works, when treating breast cancer. It can fit into the estrogen receptor, but does not activate it thus prevent- ing estrogenic effects in the tissue in question.

Thus, Tamoxifen is an “estrogen antagonist.” In truth, it’s a bit more com- plicated than that as Tamoxifen is, in fact, both an estrogen antagonist or agonist depending in the tissue in question, which means it has mixed antagonist/agonist effects, but never mind
