Storage Instructions

All products from Apex Health Performance are manufactured using a lyophilization (freeze-drying) process. This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months.

Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days.

Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. This causes the water in the vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure. This powder can be kept at room temperature until reconstitution.

Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods.

Dysfunctional Inflammation in Cystic Fibrosis Airways: From Mechanisms to Novel Therapeutic Approaches.

International journal of molecular sciences 2021

Cystic fibrosis (CF) is an inherited disorder caused by mutations in the gene encoding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein, an ATP-gated chloride channel expressed on the apical surface of airway epithelial cells. CFTR absence/dysfunction results in defective ion transport and subsequent airway surface liquid dehydration that severely compromise the airway microenvironment. Noxious agents and pathogens are entrapped inside the abnormally thick mucus layer a

Thymosin α1 protects from CTLA-4 intestinal immunopathology.

Life science alliance 2020

Indeed, although beneficial at the tumor site, unlocking a safeguard mechanism of the immune response may trigger autoimmune-like effects at the periphery, thus making the safety of immune checkpoint inhibitors a research priority. Herein, we demonstrate that thymosin α1 (Tα1), an endogenous peptide with immunomodulatory activities, can protect mice from intestinal toxicity in a murine model of immune checkpoint inhibitor-induced colitis.

Design and Development of a Novel Peptide for Treating Intestinal Inflammation.

Frontiers in immunology 2019

Intestinal inflammatory disorders, such as inflammatory bowel disease (IBD), are associated with increased pro-inflammatory cytokine secretion in the intestines. Likewise, its anti-inflammatory effects and mechanisms were also evaluated using a lipopolysaccharide (LPS)-induced intestinal inflammation murine model.

Thymosin α-1 does not correct F508del-CFTR in cystic fibrosis airway epithelia.

JCI insight 2018

Given the importance of such a drug, we aimed to characterize the underlying molecular mechanisms of action of Tα-1. The studies, which were conducted in 2 independent laboratories with identical outcome, demonstrated that Tα-1 is devoid of activity on mutant CFTR as well as on CaCC.

Thymosin alpha 1 and HIV-1: recent advances and future perspectives.

Future microbiology 2017

In spite of the consistent benefits for HIV-1 infected patients undergoing antiretroviral therapy, a complete immune reconstitution is usually not achieved. Actually, antiretroviral therapy may be frequently accompanied by immunological unresponsiveness, persistent inflammatory conditions and inefficient cytotoxic T-cell response. Thymosin alpha 1 is a thymic peptide that demonstrates a peculiar ability to restore immune system homeostasis in different physiological and pathological conditions (

Aging and Thymosin Alpha-1.

International journal of molecular sciences 2025

Aging is characterized by immune decline, mainly due to thymic involution-the age-related shrinkage of the thymus gland. This leads to reduced T-cell production, chronic inflammation, and increased susceptibility to age-related diseases. Thymosin alpha-1 (Tα1), a peptide hormone produced by the thymus, exhibits potent immunomodulatory, anti-inflammatory, and antioxidant properties. It helps restore immune function by stimulating T-cell differentiation, enhancing thymic output, and modulating de
