Thymalin Thymic T-cell maturation, IL-2 upregulation Th2 immune skewing, lymphopenia 10–20mg IM every 3–5 days Animal + human observational Strongest immune restoration data. No Lyme-specific trials Cerebrolysin Neurotrophic fact…
Hexarelin represents the most potent growth hormone-releasing peptide in the GHRP class. Binding affinity studies show it activates GHS-R1a receptors approximately 20% more strongly than ipamorelin or GHRP-2. A 1998 study in the …
Thymalin Immune modulation. Upregulates CD4+ T-cells, suppresses neuroinflammatory cytokines (TNF-α, IL-6) Indirect. Peripheral immune signals cross BBB; peptide itself does not 5–10 mg SC daily × 10–20 days (human equivalent ~0.…
The best peptides for Alzheimer's prevention work through immune modulation rather than direct amyloid clearance. Thymalin, a thymic peptide, upregulates CD4+ T-cell function and suppresses pro-inflammatory cytokines (TNF-α, IL-6…
Thymalin Thymulin receptor agonist. Restores T-cell differentiation Pre-T cells, CD4+/CD8+ populations 5–10mg subcutaneous every 3–5 days Injection only (oral bioavailability near zero) Most direct immune restoration mechanism. R…
Thymalin Thymic regeneration, T-cell maturation Immune exhaustion, T-cell depletion, thymic atrophy Clinical trials in viral recovery (Russia), observational data 10mg SC daily × 10 days Most direct mechanism for addressing docum…
Semaglutide GLP-1 receptor agonist. Slows gastric emptying, extends satiety signaling 90–120 min post-meal Strong (Phase 3 RCTs, FDA-approved for weight management) 0.25–2.4mg weekly subcutaneous Emotional eating driven by rapid …
Cerebrolysin BDNF/NGF mimetic. Reduces apoptosis, promotes synaptic plasticity Acute (0–14 days) Six RCTs, n=1,773 TBI patients. 23% mortality reduction, improved GOS scores Requires IV administration, expensive, temperature-sens…
Thymalin Thymic epithelial cell restoration, increases naïve T-cell production Corrects the thymic involution that permits EBV reactivation; restores CD4+/CD8+ ratio 10mg SC daily × 10 days, monthly cycles Moderate (Phase II data…
Not all peptides marketed for sleep have equivalent evidence. Some target symptom suppression. Others address root mechanisms. This table compares the peptides with documented relevance to shift work sleep disorder. Epithalamin (…
Thymalin Thymic restoration → Treg production → aromatase suppression 5–10 mg reconstituted, 1 mg SC daily × 10 days Subcutaneous injection −20°C before reconstitution; 2–8°C after, use within 28 days Strongest mechanistic ration…
Thymosin Alpha-1 TLR2 agonist; enhances Th1 differentiation and Treg balance 1.6mg SC twice weekly × 8-12 weeks Randomized trials in immunocompromised cohorts (HIV, chemotherapy-induced neutropenia) 40-60% reduction in infection …
The table below compares the three primary peptide categories used in clinical fatigue protocols. Each targets a distinct biological mechanism, and the choice depends on the underlying cause of the fatigue. Thymalin Immune restor…
Thymalin Thymic regeneration; restores T-regulatory cell production and reduces inflammatory cytokines 5-10mg SC every 48 hours for 10 doses Lyophilized: -20°C; reconstituted: 2-8°C, use within 28 days Immune-endocrine axis Best …
BPC-157 VEGF upregulation, tight junction repair, angiogenesis Intranasal spray (250–500 mcg/mL) or SC injection Mucosal healing visible 7–14 days; symptom improvement 3–6 weeks Preclinical animal models, case reports Strongest e…
CJC-1295 (with DAC) GHRH receptor agonist. Extends GH pulse duration Subcutaneous injection 6–8 days Sustained IGF-1 elevation, enhanced lipolysis, improved insulin sensitivity 1–2 mg weekly Gold standard for restoring youthful G…
This table compares the five most researched peptides for mental fatigue across mechanism, clinical evidence strength, administration method, and documented effects. Cerebrolysin BDNF upregulation via TrkB receptor activation 25+…
The table below compares peptides and amino acid derivatives with documented roles in detoxification pathways. Covering mechanism, clinical dosing ranges, and practical limitations. N-Acetylcysteine (NAC) Provides cysteine for gl…
Cerebrolysin BDNF, NGF, CNTF upregulation 5–10ml IM/IV, 5 days/week, 4–8 weeks Measurable at week 3–4 High (multiple RCTs, 1,200+ patients) Gold standard for post-stroke and TBI recovery; strongest human data Dihexa HGF receptor …
PT-141 (Bremelanotide) Melanocortin-4 receptor agonist Hypothalamus (dopamine pathways) 45–60 minutes subcutaneous FDA-approved; Phase 3 RCTs in 1,267 women Strongest evidence for generalized low libido in premenopausal women; wo…
