Peptide Interactions

// 14 known interactions

Synergistic(3)Compatible(3)Monitor(4)Avoid(4)

Generally well-tolerated alongside this peptide

Omega-3 fatty acids (EPA/DHA)

Supportive for brain health with no known pharmacokinetic interaction and generally neutral co-administration profile with Selank.

Vitamin B complex

Nutritional support for neurotransmitter synthesis and cognitive function without direct interaction with Selank.

Magnesium supplements

Common adjunct for anxiety and sleep that does not have known adverse interactions with Selank and is generally well tolerated.

All interaction categories

Synergistic (3)

Buspirone: Complementary 5-HT1A agonist anxiolytic activity may augment Selank's anxiolytic effects via complementary serotonergic/GABAergic modulation.
Piracetam (racetam nootropics): Cognitive-enhancing racetams may produce additive improvements in memory and cognitive function when combined with Selank's nootropic profile.
L-theanine: Amino acid with anxiolytic and relaxation-promoting effects that can reinforce Selank's calming and cognitive benefits through GABA/glutamate modulation.

Compatible (3)

Omega-3 fatty acids (EPA/DHA): Supportive for brain health with no known pharmacokinetic interaction and generally neutral co-administration profile with Selank.
Vitamin B complex: Nutritional support for neurotransmitter synthesis and cognitive function without direct interaction with Selank.
Magnesium supplements: Common adjunct for anxiety and sleep that does not have known adverse interactions with Selank and is generally well tolerated.

Monitor (4)

Benzodiazepines: Possible additive CNS depressant and sedative effects warrant monitoring of sedation, respiratory status, and consideration of benzodiazepine dose reduction.
Selective serotonin reuptake inhibitors (SSRIs): Overlapping effects on serotonergic systems may require clinical monitoring for excessive serotonergic effects and assessment of therapeutic response.
Immunosuppressants / cytokine biologics (e.g., anti-TNF agents): Selank's immunomodulatory actions could alter cytokine profiles or immune responses, so immune markers and infection risk should be monitored.
Monoamine oxidase inhibitors (MAOIs): Because Selank can modulate monoaminergic signaling, co-administration with MAOIs requires monitoring for hypertensive or serotonergic adverse reactions.

Avoid (4)

Pregnancy and breastfeeding: Insufficient human safety data on reproductive and neonatal effects, so use only if benefits clearly outweigh risks and after specialist review.
Severe immunodeficiency or active autoimmune disease: Selank's immune-modulating properties could unpredictably affect disease activity and should be used only after careful specialist evaluation.
Concomitant CNS depressants (alcohol, opioids, sedative-hypnotics): Potential for additive sedation and respiratory depression mandates careful evaluation and avoidance where feasible.
History of bipolar disorder or psychosis: Modulation of monoaminergic and cognitive systems could theoretically precipitate mood switching or psychotic symptoms, requiring psychiatric assessment before use.
