Any new or unusual symptom after dosing. Because this compound has little or no human safety data, there is no established list of 'expected' effects to reassure you against — treat anything abnormal as a signal.
Stop at the first clearly abnormal reaction and reassess. Keep the vial and lot number in case you need to describe what you actually took.
Any severe or fast-worsening symptom — difficulty breathing, chest pain, fainting, severe pain — is a 911 call regardless of the compound.
Allergic reaction: hives, swelling of the lips, tongue or throat, wheezing or dizziness can escalate to anaphylaxis within minutes — call 911 immediately. Site infection: spreading redness, heat, swelling, pus or fever is not wait-and-see; an abscess or cellulitis can need drainage or IV antibiotics. Unverified product: grey-market vials are frequently mislabelled or contaminated, so a reaction may be to endotoxin or the wrong contents, not the named compound.
A synthetic analog of the immunomodulatory tetrapeptide tuftsin, stabilised with a Pro-Gly-Pro extension. Proposed anxiolytic activity via modulation of GABA-A receptor expression, inhibition of enkephalin degradation, and effects on serotonergic tone — reportedly without the sedation, dependence, or withdrawal associated with benzodiazepines.
As with Semax: developed and studied in Russia, registered there for anxiety disorders, with a trial literature that is largely Russian-language and not independently replicated or reviewed by Western regulators.
Not FDA-approved. Registered as a medicine in Russia. Not lawfully marketed for human use in the US.
Reported tolerability is favourable in the Russian literature; independent verification is lacking. Long-term data unavailable.
A registered medicine in Russia, given intranasally per its national registration. Not FDA-reviewed; trial literature not independently validated.
Reported from clinical trials or FDA labelling as a matter of record. It is not a recommendation, and for unapproved compounds no dose has been shown safe or effective in humans.
Above is what was administered in trials or on FDA labels, reported as fact. We do not convert it into a personal protocol, calculate a dose for your body weight, or tell you what to inject or how to reconstitute it — that decision belongs with a licensed physician. See our editorial policy.
