Thyrene is an alternative weight-loss product made by Metabolic Nutrition. It is designed to increase the user’s metabolic rate, increase energy and boost fat loss.
This product features a “Thyrene Metabolic Damage Weight Loss Solution Proprietary Blend”, which in turn features six ingredients.
These include L-tyrosine, which is said to be a precursor to dopamine and other neurotransmitters. In theory, this could mean that tyrosine could help speed up the metabolism.
Coleus forskolii is a herb said to raise testosterone and increase fat loss, while guggulsterones are thought to work well with L-tyrosine and other ingredients to help people lose weight.
