Suggested Use
L-tyrosine is a non-essential amino acid important in the production of neurotransmitters such as dopamine, epinephrine, and norepinephrine – required for managing stress. It helps decrease cognitive fatigue due to physically stressful situations and promotes normal and healthy brain function including memory and concentration. It also supports normal muscle movement.
Advanced Info

L-tyrosine is an amino acid required for protein synthesis, and is a precursor for several important compounds, including thyroxin, melanin, and the neurotransmitters dopamine and norepinephrine. Dopamine and norepinephrine are important hormones and central nervous system transmitters that help maintain mood, attention and focus, and cognition. By increasing dopamine and norepinephrine at the cellular level, tyrosine may help maintain neurological health and improve mood, cognition, attention, and memory.

Tyrosine is a potent antioxidant and appears to act as an adaptogen during conditions of physical and mental stress, as shown by its ability to normalize blood pressure, alleviate fatigue, and improve cognitive function, attention, psychomotor skills, and memory. These effects may be due to tyrosine’s ability to affect brain chemicals and promote positive changes in brain pathways.

Tyrosine helps alleviate some of the effects of stress. Studies in humans show supplementation with tyrosine improves various aspects of cognitive function and physical symptoms of fatigue during exposure to physical stressors such as cold, high altitude, and extended wakefulness. Improvements are thought to be due to balancing brain chemicals and improving cognitive function.

Always order big!
I needed a minimum of 2 AWG wire to create interconnects between batteries in a large bank. If you note, these say 1/0 Gauge, not AWG. What is 1/0 Gauge? Who knows, it's fake. Meaningless, because it is not standardized so you have no clue what you are getting. What did I get for my 1/0 Gauge wire? Something that was in between 1 and 2 AWG (closer to 1). This was perfect for my needs because I knew darn well how big to order when they say gauge instead of AWG. As a rule of thumb: If they as gauge, order 3 - 4 sizes larger than you need in AWG. This will always net you larger wire than you need but I have never had it net me wire smaller than I needed. At the price I got it for during prime days, it was a steal for 2 AWG wire, so I win! I hope you found this helpful!

Heavy duty and has lasted three years so far
I have had this relay installed in the engine bay of my Lexus RX 300, functioning to link the front battery to the additional battery in the trunk whenever the ignition is on. The relay has worked reliably for about three years now with no complaints besides one minor comment, be careful when threading down the nut on the Low voltage side. It is prone to stripping

Seems to be ok for the money
We use it to power a 2000w inverter for the refrigerator and microwave on our boat where sometimes it will stay on continuously throughout the day and it hasn't let us down. As others have said, the terminals are awful close together but for the money, it's worth it.
