About This Product
Crystagen® is a Khavinson Cytogen®: a synthetic short-peptide complex (AC-6) modelled on peptides of the thymus, the gland where key immune cells mature.
More About Crystagen
It is believed to support normal immune function. Crystagen is taken orally as capsules and is often chosen by adults who want to support their immune resilience, for example during seasonal changes or as they age.
Why Crystagen?
The thymus is a small gland behind the breastbone where T cells, a key type of immune cell, mature. It gradually shrinks with age, which is one reason immune responses change over a lifetime.
Areas of Scientific Interest
- Short synthetic peptides and immune-cell activity in laboratory models
- Immune function and the ageing thymus
- Balance between different immune-cell populations
These are areas of biological investigation, not guarantees of clinical benefit.
Research Background
Crystagen belongs to a family of short peptide bioregulators developed by researchers associated with Prof. Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. Researchers have investigated how short peptides from specific tissues may interact with the cells of that tissue and influence gene activity, mostly in cell and animal studies. Much of this work has been published in Russian-language literature, and we are not aware of published controlled human trials of Crystagen itself, so the research is best read as background rather than proof of effect.
Active Ingredients
- Thymus peptide complex (AC-6)
Frequently Asked Questions
- What is Crystagen?
- Crystagen is a synthetic immune peptide bioregulator from the Khavinson Cytogen® line (AC-6), taken orally as capsules.
- Is Crystagen an injectable peptide?
- No. Crystagen is an oral dietary supplement in capsule form. It is a different class from injectable research peptides or GLP-1 medications.
- How should I take it?
- Follow the directions printed on your package. If you are unsure, ask a healthcare professional.
- What is the difference between the 20- and 60-capsule packs?
- Both contain the same capsules; the 60-capsule pack simply holds more.
- Can I take Crystagen with other bioregulators or supplements?
- Many people use several bioregulators, but combinations have not been studied as such. Check with a healthcare professional, especially if you take medications.

Crystagen
Crystagen® is a synthesized cytogen (AC-6, thymus) — copies of natural peptide fractions studied for their role in normal immune system function. Developed by the St. Petersburg Institute of Bioregulation and Gerontology. Studied for its role in supporting immune system function during periods of psychoemotional stress. Crystagen is believed to support normal immune function, and researchers have investigated short peptides for their role in immune balance. The active tripeptide stimulates T-cells, B-cells, macrophages, NK cells, and exhibits antioxidant and stress-protective effects. Available in 20-capsule and 60-capsule formats.

Revilab SL 03
Sublingual complex for immune system regulation and neuroendocrine balance. Combines pineal gland, T-cell immune, and B-cell immune peptides with licorice extract, propolis extract, mint extract, essential oils of chamomile and clove, and dihydroquercetin. Pineal peptides support biological rhythm regulation and immune signaling. T- and B-cell peptides help maintain immune balance and antibody production. Adults place 5–10 drops under the tongue 2 times a day.
