Gotratix (skeletal muscle peptide complex): what the evidence says
At a glance
What it is: an oral capsule product sold as one of the Khavinson "Cytomax" natural peptide complexes, said to be extracted from young animal skeletal muscle (product code A-18). UNVERIFIED the product code, the source tissue and the manufacturing method; these come from Nova's spec and seller descriptions, not from a primary source we could open.
What the evidence says: a PubMed search on Oct 27, 2026 found no study naming Gotratix. Only a general Khavinson review of tissue-extract peptide preparations exists; it does not mention a muscle complex trial. R1
Biggest risks: unknown. Animal-tissue extracts carry a theoretical risk of allergy and contamination, and the contents of a given capsule are not standardized. UNVERIFIED no safety data were found.

Legend: HUMAN data · ANIMAL / LAB data · UNKNOWN · UNVERIFIED: not yet confirmed against a primary source
About the evidence: there is nothing specific to this product to grade. Claims for it rest on the wider Khavinson peptide-bioregulator literature, which comes mostly from one research group in St. Petersburg and has not been independently replicated in Western randomized trials.

Is it safe?
- Unknown No safety data found.
Gray-market vials: extra risks
A gray-market vial has no quality control and no guarantee of identity, strength or sterility. We test retail vials blind under the Open Peptide Standard; see /tests/. A passing test covers one batch on one date and does not mean the compound is safe.
Is it legal?
- US: not FDA-approved; no Drugs@FDA application found (openFDA searched Oct 27, 2026).
- Compounding: not on FDA's 503A or 503B bulk-substance category lists and not on FDA's compounding safety-risk page. R2, R3, R4
- Sport: not named on WADA's 2026 Prohibited List. R5
