Workout recovery support; Sleep and relaxation support; Neurotransmitter balance; Healthy hormone rhythm support
Adults with active training routines or those with busy schedules seeking evening wind-down support.
Take 5 tablets before exercise and/or at bedtime with plenty of water at least two hours after the last meal; taking on an empty stomach supports amino acid uptake.
Arginine serves as a nitric oxide precursor that may influence pituitary signaling, while the pyroglutamate form supports uptake and neurotransmitter pathways linked to growth hormone release.
Caution: May cause gastrointestinal upset or lower blood pressure in some people; avoid combining with high-dose vasodilators due to additive effects.
Lysine is an essential amino acid that may modulate pituitary and hypothalamic signaling when paired with arginine to support growth hormone pulses.
Caution: High doses may cause stomach discomfort; take with water and away from large calcium doses that can compete for absorption.
GABA is an inhibitory neurotransmitter that may promote relaxation and influence hypothalamic-pituitary signaling related to growth hormone rhythms.
Caution: May cause drowsiness or tingling sensations; use caution before activities requiring alertness.
L-Dopa is a dopamine precursor that can stimulate dopaminergic pathways, which are associated with pituitary growth hormone secretion.
Caution: May affect mood, blood pressure, or interact with medications that alter dopamine; avoid use with MAO inhibitors.
5-HTP is a serotonin precursor that may influence sleep and circadian neurochemistry connected to nocturnal growth hormone patterns.
Caution: May cause drowsiness or gastrointestinal upset and can interact with serotonergic drugs or supplements.
Amino acids such as arginine and lysine engage nitric oxide and pituitary pathways that are linked to growth hormone pulses. Neurotransmitter support from GABA, L-Dopa from velvet bean, and serotonin precursor 5-HTP targets relaxation, dopaminergic drive, and sleep-related timing cues to coordinate signaling. Together, these pathways align nutrient and neurochemical cues that may influence nocturnal and exercise-associated hormone rhythms.
Label Warning: Not for children, or for women who are pregnant, may become pregnant, or breastfeeding. Do not use if diagnosed with any form of cancer. Consult a physician before use if you have psychiatric disturbances, ulcers, diabetes, tremors, epilepsy, asthma, urinary incontinence, cardiac arrhythmia, high blood pressure, or carpal tunnel syndrome, or if you are taking warfarin (Coumadin) or any other prescription medication. California Proposition 65: reproductive harm. Discontinue or reduce use if nausea, excessive salivation, vomiting, diarrhea, muscle spasms, cramps, excessive urination, insomnia, headache, cardiac arrhythmias, high blood pressure, or mood changes occur.
Who should be cautious: People with bleeding risks or on anticoagulants, including warfarin, due to ginkgo and high-dose niacin. Individuals with blood pressure concerns or arrhythmias, seizures, mood disorders, glaucoma risk, or cognitive medication use due to GABAergic agents, Huperzine A, DMAE, and L-Dopa from velvet bean. Those with diabetes or on blood-sugar-affecting medications due to chromium and niacin. People sensitive to high-dose niacin flushing. Those on antidepressants or other serotonergic drugs due to 5-HTP. People with asthma or ulcer history should be cautious. If combining with medications that may interact, discuss with a healthcare provider before use.
Storage: Keep out of reach of children.
Many active users report better energy, muscle recovery, and workout performance with consistent use.
Several customers mention deeper or more restful sleep after taking the tablets as directed.
Some find the tablets hard to swallow, and a few report stomach upset or diarrhea.
