The question isn't whether peptides replace biologics. They don't, and no responsible researcher claims otherwise. The question is whether they address the 60% of Crohn's patients who don't achieve mucosal healing with anti-TNF m…
Before selecting a peptide, researchers must match the compound's mechanism to the specific sleep disruption pattern under investigation. The table below ranks peptides by primary mechanism, strength of clinical evidence, and pra…
Copper Peptide (GHK-Cu) Activates lysyl oxidase and prolyl hydroxylase for collagen cross-linking 30+ peer-reviewed trials, biopsy-confirmed collagen increase 0.01–0.1% (1–10 micromolar) Unstable pH 7.0; requires 5.0–6.5 buffer S…
Peripheral neuropathy doesn't improve because you mask the pain. It improves when damaged axons regrow, when Schwann cells remyelinate nerve fibers, and when microvascular perfusion to peripheral nerves normalizes. Standard pharm…
Before selecting a peptide for energy enhancement, understand the biological pathway each targets. Thymalin corrects immune-mediated fatigue, MK-677 restores anabolic hormonal balance, Cerebrolysin enhances neurometabolic efficie…
| Peptide | Primary Mechanism | Typical Dosage | Injection Frequency | Best Use Case | Storage Requirement | Professional Assessment ||—|—|—|—|—|—|| BPC-157 | Upregulates VEGF and FGF receptors; accelerates collagen synthesis and…
Thymosin Beta-4 (TB-4) Promotes keratinocyte migration, reduces mast cell degranulation, upregulates IL-10 IL-1beta, TNF-alpha, IL-10 38% reduction in dermal inflammation scores in murine contact dermatitis model 7–14 days for er…
Ghrelin Analogs (Relamorelin, TZP-101) GHS-R1a receptors on enteric neurons Stimulates vagal nerve activation and ICC pacemaker frequency, increasing antral peristalsis 35–50% reduction in gastric retention time in Phase 2 diabet…
BPC-157 Growth factor receptor activation → fibroblast proliferation Tissue repair, cartilage regeneration Subcutaneous 200–500 mcg/day Most effective for structural TMJ damage (cartilage erosion, disc displacement). Addresses ro…
BPC-157 VEGF upregulation for mucosal repair, angiogenesis in damaged tissue 250–500 mcg SC daily or 1–2 mg oral daily 7–14 days for measurable barrier improvement Rodent colitis models show 40–60% lesion reduction in 14 days; hu…
The table below ranks peptides by mechanism, primary cognitive domain affected, bioavailability, and evidence quality. Ranking is based on the strength of mechanistic data (receptor-level evidence), replicability across independe…
DSIP Direct hypothalamic delta-wave modulation 12–18 minutes (animal models, limited human data) Increases slow-wave sleep (SWS) by 22–38% 30–60 minutes Moderate. Strong preclinical, sparse human RCTs Best direct sleep-onset agen…
Thymalin Immune modulation Thymulin receptor → T-cell maturation → cytokine normalization 10mg daily × 10 days, then 10mg 2×/week Russian Academy study: 40% reduction in fatigue severity scores over 12 weeks Best for immune-drive…
Before the table. Mechanism determines ranking. Cerebrolysin protects and repairs. Dihexa creates and expands. P21 consolidates and strengthens. Comparing them directly ignores that memory formation operates through sequential st…
Hydrolysed collagen peptides (Type I/III) Provides amino acids (Gly-Pro-Hyp) for fibroblast collagen synthesis 2.5g/day × 24 weeks: 15% elasticity increase, 11% cellulite reduction (Journal of Medicinal Food) Oral. Survives diges…
CJC-1295/Ipamorelin GHRH + ghrelin receptor agonism → restored pulsatile GH secretion 4.2cm mean abdominal circumference reduction at 24 weeks (University of Virginia study) 200–300mcg each, subcutaneous, pre-bed 8–12 weeks for m…
