Crystagen (Crystagen (Immune Peptide Bioregulator))
A short synthetic peptide bioregulator from the Khavinson family targeted at immune (thymus/lymphoid) tissue. It is used in the bioregulator community to support immune regulation and resilience, typically in short repeated courses.
How it works
As a signal peptide, it is proposed to enter cells and regulate gene expression in immune tissue, supporting normal thymic and lymphoid function, immune cell maturation, and balanced immune responses.
Key facts
- Molecular weight: ~ (short peptide)
- Half-life: Short (peptide)
- Bioavailability: Oral (encapsulated) or subcutaneous
- Storage: Room temperature (capsules) or refrigerate (injectable).
Dosing overview
- Typical dose: ~1-2 capsules/day or short injectable courses
- Frequency: Once daily
- Duration: 10-30 day courses
- Route: Oral capsule or subcutaneous
Protocol notes
- Taken as short repeatable courses (often 10-30 days), a few times per year.
- Oral encapsulated forms are taken once daily, usually on an empty stomach.
- Often cycled seasonally for immune support.
Reported benefits
- Immune regulation support
- Thymic/lymphoid tissue support (proposed)
- Immune resilience

- Unknown long-term effects
Research
- Immune peptide bioregulators (2017): Reported to support thymic and lymphoid tissue function in regional research studies.
Community reviews of Crystagen
- injection_journal rated it 4/5 - Worth adding to the protocol: Crystagen has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
- recon_math_ray rated it 5/5 - Noticed clear benefits within weeks: Added Crystagen to my protocol about 3 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
- data_driven_dan rated it 4/5 - Genuinely effective after 1 month: Been using Crystagen for about 1 month and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
