Injection site reaction (erythema, tenderness) 15–30% per dose Local inflammatory cytokine release (IL-1β, IL-6) at injection site Mild. Resolves within 24 hours Rotate injection sites, use 25–27 gauge needle, inject slowly Expec…
Most nootropic compounds fall into one of two categories: they either protect existing neurons from damage (neuroprotection) or they enhance neurotransmitter signaling efficiency (neuromodulation). Dihexa belongs to a much rarer …
Pe-22-28 TLR4 modulation → BDNF upregulation Hippocampus > SVZ > cortex 10–50 μM Preclinical only. No human trials Best for hippocampal-specific models; weaker in cortical injury Dihexa HGF/Met receptor agonism Broad. Hippocampus…

ALT (liver enzyme) 10–40 IU/L 15–55 IU/L Mild elevation common; reflects hepatic metabolic activity, not damage Hold protocol if >3× baseline or >120 IU/L AST (liver enzyme) 15–50 IU/L Parallels ALT; disproportionate AST rise sug…
Primary Mechanism Activates telomerase enzyme; extends telomere length during cell division Restores thymic epithelial function; increases naive T-cell production Mechanistically distinct. One addresses chromosomal aging, the oth…
The table below breaks down the critical differences across mechanism, research context, and practical considerations. Primary Mechanism Telomerase activation (TERT upregulation) CNS-specific gene regulation (BDNF, NGF, synapsin-…
Research published in the Journal of Neuroinflammation found that ARA-290 reduced neuropathic pain scores by 42% in patients with sarcoidosis-associated small fiber neuropathy. A result VIP has never replicated in controlled tria…
Primary Mechanism Restores NAD+ pools to activate sirtuins, PARPs, and support mitochondrial biogenesis via PGC-1α Stabilizes cardiolipin in the inner mitochondrial membrane, preventing oxidative damage to electron transport chai…
Growth Hormone Secretagogues (MK 677, CJC-1295) Anabolic signaling, tissue repair studies Daily to weekly depending on compound half-life –20°C (lyophilised), some formulations room-stable 14–28 days at 2–8°C Injection timing rel…
Research published in the European Journal of Pharmacology found that DSIP (Delta Sleep-Inducing Peptide) modulates sleep-wake cycles through hypothalamic regulation. It doesn't sedate, it synchronizes endogenous delta wave patte…
Growth Hormone Secretagogues (MK 677, GHRP-2) Elevates IGF-1, suppresses TSH via negative feedback Dose ≥4 hours after thyroid medication TSH suppression 20–35% in first 8 weeks High interaction risk. Monitor TSH monthly during i…
Research comparing DSIP (Delta Sleep-Inducing Peptide) and Pinealon typically frames them as interchangeable 'brain peptides'. But that framing misses the fundamental difference in their mechanisms. DSIP acts on delta-wave sleep …

DSS-induced colitis (mouse) Barrier protection + anti-inflammatory 48% reduction in disease activity index; 62% decrease in myeloperoxidase activity 5 mg/kg IP daily × 7 days Strongest evidence for barrier repair. Mechanism trans…
Inflammatory Bowel Disease Models Reduces colonic inflammation 55–65% in DSS-induced colitis; oral administration viable; minimal systemic effects Reduces inflammation 30–40% but requires parenteral routes; systemic immune modula…
The Amidate modification. Replacement of the C-terminal carboxyl group with an amide. Serves two functions: it prevents degradation by carboxypeptidases (enzymes that cleave peptides from the C-terminus), and it increases lipophi…
Selank operates through two distinct pathways that mature on different schedules. The anxiolytic effect. Mediated through enkephalin degradation inhibition and GABAergic potentiation. Begins within 24–48 hours of intranasal admin…
Semax Amidate Melanocortin modulation + BDNF/NGF synthesis 140% increase (hippocampus, 24h) 60–90 min (acute); 7–14 days (sustained) Low. Minimal receptor desensitization at standard doses Best choice for sustained focus enhancem…
