Standard Vial or Pen Format ( RUO )

Overview

Glutathione (GSH) is a powerful tripeptide antioxidant produced naturally in the body, essential for maintaining redox balance, neutralizing harmful free radicals, and supporting detoxification. It plays key roles in DNA repair, immune regulation, and mitochondrial protection. With its higher dosage, L-Glutathione 3000mg is designed for those seeking enhanced antioxidant support for overall wellness, anti-aging, and recovery from oxidative stress.

Research

Glutathione exists in reduced (GSH) and oxidized (GSSG) forms, with a healthy high GSH/GSSG ratio being crucial for optimal cellular function. It protects against oxidative damage by neutralizing reactive oxygen species (ROS) such as hydrogen peroxide and superoxide, safeguarding proteins, lipids, and DNA.

In mitochondria, GSH prevents oxidative injury and apoptosis, while in the nucleus it supports DNA synthesis and repair. GSH also plays a critical role in detoxifying xenobiotics, maintaining cysteine levels, and regulating redox-sensitive transcription factors.

Research shows that GSH imbalances are linked to neurodegenerative conditions, liver disease, diabetes, and accelerated aging. In oncology, it has a dual nature β€” removing carcinogens and protecting healthy cells, but potentially aiding tumor resistance to chemotherapy and radiotherapy when elevated in cancer cells.

Therapeutic strategies focus on both boosting GSH for antioxidant defense in healthy tissues and selectively depleting it in tumors to improve treatment outcomes. The higher dosage in L-Glutathione 3000mg offers robust support for individuals under high oxidative stress or needing intensive detoxification.

Best Practices for Storing Peptides

To maintain the reliability of laboratory results, correct peptide storage is essential. Proper storage conditions help preserve peptide stability for years while protecting against contamination, oxidation, and breakdown. Although certain peptides are more sensitive than others, following these best practices will greatly extend their shelf life and structural integrity.

  • Short-Term Storage (days to months): Keep peptides cool and protected from light. Temperatures below 4 Β°C (39 Β°F) are generally suitable. Lyophilized peptides often remain stable at room temperature for several weeks, but refrigeration is still preferred if use is not immediate.
  • Long-Term Storage (months to years): Store peptides at –80 Β°C (–112 Β°F) for maximum stability. Avoid frost-free freezers, as defrost cycles can cause damaging temperature fluctuations.
  • Minimize Freeze–Thaw Cycles: Repeated freezing and thawing accelerates degradation. Instead, divide peptides into aliquots before freezing.

Preventing Oxidation & Moisture Damage

Peptides can be compromised by exposure to moisture and airβ€”especially immediately after removal from a freezer.

  • Let the vial warm to room temperature before opening to prevent condensation.
  • Keep containers sealed as much as possible, and if possible, reseal under a dry, inert gas such as nitrogen or argon.
  • Amino acids like cysteine (C), methionine (M), and tryptophan (W) are particularly sensitive to oxidation.


Storing Peptides in Solution

Peptides in solution have a much shorter lifespan compared to lyophilized form and are prone to bacterial degradation.

  • If storage in solution is unavoidable, use sterile buffers at pH 5–6.
  • Prepare single-use aliquots to avoid repeated freeze–thaw cycles.
  • Most peptide solutions are stable for up to 30 days at 4 Β°C (39 Β°F), but sensitive sequences should remain frozen when not in use.


Containers for Peptide Storage

Select containers that are clean, intact, chemically resistant, and appropriately sized for the sample.

  • Glass vials: offer clarity, durability, and chemical resistance.
  • Plastic vials: polystyrene (clear but less resistant) or polypropylene (translucent but chemically resistant).
  • Peptides shipped in plastic vials may be transferred to glass for long-term storage if desired.
