Glutamine by Optimum NutritionOPTIMUM L GLUTAMINE Glutamine is the most abundant amino acid in the body and plays an important role in muscle. During prolonged periods of intense exercise glutamine levels can be depleted which may limit protein synthesis. Our Glutamine Powder is a simple way to supplement your diet with this amino acid. Just one table spoon of Glutamine Powder provides more glutamine than 4 jumbo eggs, 4 oz. of lean beef, cup of soybeans or a 4 oz. chicken breast.

Good stuff!
Size: 5FT, Style: 8AWG
Good quality silicone insulated wire. It’s very flexible and solders really well. The silicone insulation can’t be beat for heat resistance. I will definitely purchase again.
