L-Carnitine is a very important amino acid used in the breakdown of fat for energy. Increasing L-Carnitine levels above and beyond what one would normally consume from diet has the ability to increase fat burning, even in the presence of carbohydrate. This can be an incredibly beneficial effect, but there are a couple catches. For one, the amount of L-Carnitine one would have to consume orally in order to elicit a benefit would far outweigh the costs, and would most likely lead to stomach upset. L-Carnitine levels are tightly controlled, and the cost of L-Carnitine is not cheap, so eating 5-10 grams of it per day would make it impractical for our purposes. The other catch is that the hormone insulin must be present at the same time as the L-Carnitine levels are increased. Consuming enough L-Carnitine and then enough sugar to elicit the desired insulin response would most likely offset the benefits. Injectable L-Carnitine however, allows the advanced user to bypass the gastric limitations, and dramatically increase blood levels of Carnitine at a fraction of the dose. In addition, advanced users may also combine this injectable amino acid with 1 or 2 IU’s of insulin, to increase the absorption of the L-Carnitine into the cells where it is needed to burn fat for energy. It is not advised by this author that anyone attempt the usage of insulin, because of its very real dangers. However, a small glass of orange juice should provide enough of an insulin spike, shortly after the intramuscularly delivered L-Carnitine enters the bloodstream, in order to elicit the desired response. An initial loading phase of 250-500mg per day is recommended, and thereafter, 100-200mg per day is all that is needed to keep the levels consistently high.

By now many people are already familiar with the benefits of Beta-Alanine. The studies showing enhanced sports performance, delayed fatigue and increased endurance are all undeniable. Beta-Alanine truly is a useful amino acid when it comes to athleticism. But did you know that Beta-Alanine supplementation benefits are really due to an amino acid known as L-Carnosine? Much in the same way that L-Glutathione breaks down in the stomach, so does L-Carnosine. The stomach acids break down L-Carnosine into L-Histidine and Beta-Alanine. Most people with an abundant amount of protein ingestion will have more than enough L-Histidine to build L-Carnosine. But Beta-Alanine is a unique amino acid and really needs to be supplemented in order to see its full benefits. So people have started ingesting several grams of Beta-Alanine preworkout in order to experience the increased endurance and delayed muscle fatigue. But many users of Beta-Alanine complain of a tingling sensation when they ingest it. While some people don’t find it to be a problem, others complain that it is very uncomfortable, similar to the flushing sensation that occurs with Niacin ingestion. Also, if you were to take too much Beta-Alanine, stomach upset and diarrhea can occur. The alternative to this would be to deliver, intramuscularly, a sterile solution of L-Carnosine. Once in the bloodstream, L-Carnosine is left intact and can enter the muscle cells, where it quenches the excess hydrogen ions that build up in muscle tissue, affecting pH and leading to muscle fatigue. A daily dose of 200mg intramuscularly will optimize L-Carnosine levels over a period of a few weeks, at which point the user will begin to notice its benefits
