L-Tryptophan Test Kit - Purity Test Kit for L-Tryptophan

Find L-Tryptophan purity test kits and reagent tests selected for fast substance identification and cleaner checking. L-Tryptophan is an essential amino acid, meaning the human body does not produce it naturally, but is required for the body's healthy functioning. L-Tryptophan is present in a wide range of foods including beans, nuts, milk, and poultry. L-Tryptophan is a precursor to 5-HTP (which is a precursor to serotonin) and is sold as a sleep aid and mood enhancer. L-Tryptophan was banned by the FDA in the 1990s because of contamination in the production process, but was re-released onto the U.S. market in 2001 after the FDA published a revised estimate of the risks. During the 1990s, 5-HTP was sold for human consumption in the US and grew in popularity partially because L-Tryptophan was unavailable.

Drug purity testing kits come in 3 types: reagent tests, TLC and test strips. Use a multi-reagent kit to identify most common substances. Pair reagents with a TLC test kit to discover number and amount (%) of almost all ingredients. Use test strips to rule out fentanyl, nitazenes or xylazine.
