What Crystagen is
Crystagen is a short peptide bioregulator from the Khavinson series, described in Russian-language work as an immune-system regulator acting on thymic and lymphoid tissue in animal models.
As with the rest of that series, the research is real but concentrated in a small number of laboratories with limited independent replication, so claims should be read conservatively.
What the evidence base looks like
Published data is thin and concentrated in a small number of laboratories, so anything stated about outcomes should be treated as exploratory.
Our library records roughly 8 relevant publications for Crystagen and grades the evidence as limited. That grade describes the weight of research, not a judgement about safety or effect, and it is reviewed as new work is published.
Supplier quality: what to check on Crystagen
Bioregulator tetrapeptides are cheap to synthesise and hard to distinguish by eye, making batch-matched analysis essential.
The practical checklist is the same on every product but weighted differently here: a batch-matched certificate of analysis, an identity method appropriate to this molecule rather than purity alone, clear peptide content per 20mg vial, and a supplier that will answer a technical question before taking payment.
Typical UK pricing
The lowest price we currently track for a 20mg vial is £59.90, against a market median nearer £85. Compare on price per milligram rather than per vial, because vial sizes across suppliers are rarely identical.
A listing well below the tracked low is worth investigating rather than celebrating. On this compound the cost of doing it properly is largely analytical, and that is the first thing an unusually cheap supplier stops paying for.
