slow-medium-fast-acting-proteins

Posted in: Ask the Experts | May 9, 2009

I read your catalogs all the time. Lately, I'm seeing that you guys are really emphasizing ultra-fast-acting proteins like these new hydrolyzed whey products. So here's my question: If I'm consuming protein all day, both from food sources and from protein shakes, don't I always have aminos cruising my bloodstream? If I'm perpetually maxed on bioavailable aminos, why do I need to worry about slow-, medium- or fast-acting proteins? Thanks and keep up the good work!

Even if you have ingested a fair dose of protein before exercise, you will stay in the protein catabolic state after rigourous exercise until you have taken in enough amino acids. You obviously want to switch from the catabolic state to the anabolic state as soon as possible, right? To do so, you need to rapidly elevate blood amino acid and insulin levels (Insulin is an anabolic hormone that helps transport amino acids into hungry muscle cells).

The best way to accomplish this goal is to ingest a serving of BioQuest MyoZene immediately after exercise. This high-tech post-exercise supplement provides an elite form of protein that can be absorbed almost instantly upon ingestion, without going through the normal digestive processes.

Consequently, a massive surge of anabolic nutrients are rapidly transported to muscle tissue, where they help trigger new muscle synthesis at a greatly accelerated rate. In addition to the highest quality whey protein hydrolysate, MyoZene also contains a large dose of added leucine. This branched-chain amino acid is the key regulator of muscle protein anabolism. Finally, MyoZene provides a host of other beneficial ingredients such as glutamine, antioxidants, KIC, etc.

Use of a specialized post-workout supplement such as this is proving to be the edge many bodybuilders need to achieve dramatic muscle gains.
