5-HTP is rapidly absorbed with a t max of ≈1.5 h, and rapidly eliminated with a half-life of ≈1.5 – 2 h. Co-administration of a decarboxylase inhibitor (e.g., carbidopa, benserazide ) doubles the half-life of 5-HTP to ≈ 3 – 4 h , [ 37 ] [ 34 ] and enhances exposure several-fold, depending on the dosing regimen.
α-Methyl-5-hydroxytryptophan (α-Me-5-HTP) is a synthetic tryptamine derivative, an artificial amino acid, and a prodrug of α-methylserotonin. [ 1 ] [ 2 ] It is the α- methylated derivative of 5-hydroxytryptophan (5-HTP), while αMS is the α-methylated analogue of serotonin .
5-HTP is produced from the amino acid tryptophan through the action of the enzyme tryptophan hydroxylase. Tryptophan hydroxylase is one of the biopterin-dependent aromatic amino acid hydroxylases. Production of 5-HTP is the rate-limiting step in 5-HT (serotonin) synthesis. 5-HTP is normally rapidly converted to 5-HT by amino acid decarboxylase. [1]
Menopause typically occurs at some point between 47 and 54 years of age. [8] According to various data, more than 95% of women have their last period between the ages of 44–56 (median 49–50). 2% of women under the age of 40, 5% between the ages of 40–45 and the same number between the ages of 55–58 have their last bleeding.

5-MeO-AMT blotters. 5-MeO-AMT is supposedly sold in 4 mg tablets by the street name Alpha-O and taken as a recreational drug.Since the DEA arrests of the makers of a huge percentage of the United States' LSD in 2000, 5-MeO-AMT may have occasionally been sold under the guise of LSD in liquid, sugar cube, or blotter form, though this may be due to DEA reports of finding it on sugar cubes and ...
5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems. [ 1 ] [ 2 ] [ 3 ] They mediate both excitatory and inhibitory neurotransmission .
