TAD 600 is a pharmaceutically manufactured injectable glutathione preparation containing 600 mg reduced L-glutathione (GSH) in 4 ml solution per vial, produced by Biomedica Foscama under GMP-compliant conditions. The active substance represents the most important endogenous tripeptide antioxidant in the human body and is involved in central processes of cellular detoxification, redox balance and hepatic metabolism.
Mechanism of Action: Antioxidant Protection and Hepatocellular Detoxification
L-Glutathione (γ-L-glutamyl-L-cysteinyl-glycine) neutralises reactive oxygen species (ROS) through direct electron donation and serves as an essential co-substrate for glutathione peroxidase (GPx). Hepatocytes metabolise anabolic androgenic steroids (AAS) via CYP450 enzymes, generating electrophilic intermediate products that require GSH-dependent glutathione S-transferases (GST) for conjugation and renal excretion. TAD 600 provides exogenously available, already-reduced GSH, thereby bypassing intracellular de novo synthesis, which can become limited under oxidative stress. Studies demonstrate that intravenously administered L-glutathione significantly raises hepatic GSH concentrations and can measurably reduce markers such as ALT and AST. Parenteral administration (i.m./i.v.) ensures near-complete bioavailability, as oral glutathione undergoes extensive hydrolysis in the gastrointestinal tract.
Application Context: Liver Regeneration During and After AAS Cycles
Oral 17-alpha-alkylated steroids and high-dose injectable AAS protocols place considerable demands on hepatic biotransformation capacity. TAD 600 is used in this context to maintain glutathione homeostasis, reduce oxidative liver stress and accelerate the regeneration phase following a cycle. Administration takes place after reconstitution with a suitable solvent (water for injections, Ph. Eur.) and is possible both intramuscularly and intravenously. Each pack contains 10 vials, sufficient for a structured protocol period of two to four weeks. Product quality is assured through HPLC purity analysis and GMP batch release, guaranteeing a reproducible active substance concentration of ≥99% L-glutathione.
Formulation and Pharmaceutical Quality
Each vial contains 600 mg reduced L-glutathione in lyophilised or liquid form for parenteral reconstitution. The formulation meets the requirements of the European Pharmacopoeia (Ph. Eur.) with regard to purity, sterility and freedom from pyrogens. Biomedica Foscama employs closed aseptic filling lines and batch traceability in accordance with EU GMP guidelines. TAD 600 contains no anabolic or hormonally active substances and is designed exclusively as a supportive and adjunct preparation.
