Half-Life No published human value; PubMed lists no pharmacokinetic study of Crystagen in people or animals Dosage Calculator Calculate exact dosing for Crystagen. https://www.bodyhackguide.co/tools/dosage Dosing data for Crystagen is being researched. Check the compound page (https://www.bodyhackguide.co/compound/crystagen) for the latest information. ## Side Effects & Safety \## Human data PubMed lists no study of Crystagen in people, so no human adverse event data for Crystagen have been published in an indexed journal. ## Animal and cell data PubMed contains no animal toxicology study of Crystagen. In laboratory cultures of human blood cells, the tripeptide T-36 (Glu-Asp-Pro) did not change lymphocyte survival or granulocyte engulfment and bactericidal activity (PMID: 22485217; PMID: 22803085). That is a cell-culture finding and says nothing about safety in people. ## Statements from the developers A 2020 review from the Khavinson group states that peptides of this kind have virtually no side effects (PMID: 32987757). That statement concerns peptides in general and is not backed by a published safety study of Crystagen. Contraindications No contraindications for Crystagen have been studied. A mechanism-based caution follows from the cell work: the published studies describe effects on immune cells, including increased lymphocyte proliferation (PMID: 22485217) and B-cell activation (PMID: 28976144). No study has examined Crystagen in people with immune or autoimmune disease, in people taking immune-modifying drugs, in pregnancy or in children.
