The Efficacy and Safety of an Amino Acid Supplement in Adults

A 90-day, Double-blind, Placebo-controlled, Randomized, Parallel-Group Efficacy and Safety Study of an Amino Acid Supplement in Adults

The primary objective of this clinical trial is to determine the efficacy of once daily oral AAS use, as compared to placebo, in increasing serum IGF-1 concentrations within adults aged 35-75 years for up to 90 days. Additionally, the safety and tolerability of the AAS, as compared to placebo, will be measured by the occurrence of and/or changes in treatment-emergent adverse events (AEs).

For the study population, the eligibility criteria limit the presence of confounding variables that could influence study outcomes. Participants will be men and women between 35 and 75 years of age to account for the age range in which humans experience a decline in HGH/IGF-1. Each participant will be deemed eligible to participate by the Qualified Investigator (QI) by means of an extensive review of medical history, laboratory results, and physical examination. Participants will be required to have body mass index (BMI) measurements between 18.5 and 35.0 kg/m2 to ensure that their body weight/composition will not have a confounding effect on their HGH levels (18, 19) and to facilitate generalizability. Participants will be required to maintain current medication and supplements use and sleep throughout the study. They must also abstain from any over-the counter (OTC) medications and/or supplements that may affect the efficacy or safety of the AAS.

7. Current diagnosis or history of a thyroid-related disorder and/or disease
8. Current diagnosis of liver diseases
9. Current diagnosis of primary hypercholesterolemia (LDL-C 160-189 mg/dl [4.1-4.8 mmol/l]; non-HDL-C 190-219 mg/dl [4.9-5.6 mmol/l])
10. Current diagnosis of primary hypertriglyceridemia (triglycerides >150 mg/dl, fasting)
11. Current diagnosis of stage 2 hypertension (> 140/90 mmHg)
12. Current diagnosis of type 1 or type 2 diabetes mellitus (HbA1c > 6.5%)
13. History or presence of gastrointestinal (including prior bariatric bypass surgery), hepatic or renal disease, or any other condition that may interfere with the absorption, distribution, metabolism, or excretion of IPs, based on the opinion of the QI
14. History of cardiovascular disease and/or significant cardiovascular event in the past 6 months. Participants with no significant cardiovascular event on stable medication may be included after assessment by the QI on a case-by-case basis
15. History (within past two years at screening) or presence of diagnosis of alcohol abuse, a substance abuse disorder, known drug dependence, or seeking treatment for alcohol or substance abuse related disorder.
16. Current use of prescribed medications, over-the-counter (OTC) medications, or supplements which may affect the efficacy and/or safety of the IP

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Amino Acid Supplement; Participants will be instructed to take four (4) capsules of Amino Acid Supplement with a full glass of water daily for up to 90 days, starting on day 1. No substance other than water (i.e., food, drink other than water, and/or medication, supplement, vitamin, and/or mineral) can be consumed two hours before or after taking the Investigational Product (IP). The IP must be consistently consumed immediately before nighttime sleep throughout the study. If a dose is missed participants are instructed to record the missed dose in their study journal. Missed doses will not be taken at a later time or date. If any substance other than water is consumed two hours before or after taking the IP, that IP use will be counted as a missed dose. Participants will be advised not to exceed four (4) capsules daily.	Drug: Amino Acid Supplement; Four capsules of Amino Acid Supplement will be taken once a day for 90 days.
Placebo Comparator: Placebo; Participants will be instructed to take four (4) capsules of Placebo with a full glass of water daily for up to 90 days, starting on day 1. No substance other than water (i.e., food, drink other than water, and/or medication, supplement, vitamin, and/or mineral) can be consumed two hours before or after taking the placebo. The placebo must be consistently consumed immediately before nighttime sleep throughout the study. If a dose is missed participants are instructed to record the missed dose in their study journal. Missed doses will not be taken at a later time or date. If any substance other than water is consumed two hours before or after taking the placebo, that placebo use will be counted as a missed dose. Participants will be advised not to exceed four (4) capsules daily.	Other: Placebo; Four capsules of Placebo will be taken once a day for 90 days.
