Cerebrolysin BDNF upregulation, synaptic repair Multiple Phase 3 trials (post-stroke depression) Not approved in the U.S. Most evidence exists for this compound. Used clinically in Europe and Asia Dihexa HGF/Met receptor activati…
Selank GABA-A receptor modulation, enkephalin metabolism inhibition Intranasal spray Strong (multiple RCTs in GAD, social anxiety) 30–60 minutes Most robust clinical data for anxiety-specific use; non-sedating; no tolerance devel…
Growth Hormone-Releasing Peptides (CJC-1295, Ipamorelin, GHRP-2) Stimulate pituitary GH secretion via ghrelin receptor activation Increased IGF-1 levels, improved recovery, enhanced body composition 100–200 mcg subcutaneously bef…
BPC-157 peptide VEGF upregulation, angiogenesis enhancement, tight junction stabilization Preclinical animal models (high quality), human case reports (limited) Direct epithelial regeneration demonstrated in rodent IBD models 10 …
GH Secretagogues (GHRP-2, Ipamorelin) Ghrelin receptor agonism → pituitary GH release 0.8–1.5kg Moderate. Via enhanced sleep quality $80–$140 Best evidence for measurable hypertrophy when stacked with GHRH analogue GHRH Analogues…
Tendon-bone healing (ACL repair) 8–12 weeks to weight-bearing 5–8 weeks to weight-bearing 30–40% faster return to activity; documented in 2024 AJSM study Surgical site infection rate 2–5% (varies by procedure) 0.8–2.1% with BPC-1…
Peptides occupy a unique space between conservative management (NSAIDs, physical therapy) and invasive procedures (corticosteroid injections, surgery). Understanding where they fit requires comparing mechanisms, timelines, and ou…
BPC-157 Peptide Upregulates VEGF and collagen synthesis; enhances fibroblast migration 4–8 weeks for peak benefit Increases Type I collagen density by 40–60% (animal data) Lower. Strengthens tendon structure Evidence strongest in…
Cerebrolysin NGF/BDNF mimetic. Synaptic remodeling and acetylcholine synthesis 5–30mL IV or IM, 2–3x weekly Refrigerate 2–8°C; avoid freezing Pre-mixed solution. Use within 28 days after opening Strong clinical evidence in MCI an…
Every peptide mentioned so far shows promise in preclinical research. But preclinical means animal models, isolated cell cultures, or small human safety trials. No peptide has completed a Phase 3 randomized controlled trial for A…
CJC-1295/Ipamorelin GHRH analog + ghrelin mimetic. Synergistic GH release without cortisol elevation +1.2–2.6 kg over 12–24 weeks (DEXA-measured) Visceral fat reduction 8–12% in deficit or maintenance intake Subcutaneous injectio…
MK 677 Growth hormone secretagogue; increases IGF-1 and mitochondrial biogenesis VO2 max, lactate threshold, glycogen storage rate 10-25mg daily, oral Best-supported peptide for endurance; effects are training-dependent and requi…

BPC-157 Peptide Upregulates VEGF receptor signaling, promotes angiogenesis and fibroblast migration 4–8 weeks in animal models (40–60% faster than controls) Multiple rat and equine studies; no human RCTs Requires injection; dosin…
BPC-157 VEGF receptor activation, fibroblast recruitment, collagen synthesis Strong preclinical (rat/rabbit models), no human RCTs 10–50 mcg/kg daily Most studied for ligament/tendon repair. Mechanism is well-characterized, human…
A common source of confusion is the relationship between legal status and drug test detection. These are separate issues that require separate analysis.
Athletes can be tested at any time, not just during competitions. Out-of-competition testing targets substances that provide training advantages even when not used immediately before competition. Peptides fall squarely into this …
What expiration dates mean: Conservative estimate of guaranteed potency Usually based on accelerated stability testing Designed to ensure 90-100% potency through date Regulatory and liability considerations Why stated dates are c…
Lyophilized (freeze-dried) powder: Most peptides sold in this form Moisture removed via freeze-drying Very stable when dry Can last years if stored properly Requires reconstitution before use Lyophilized stability: Freezer (-20°C…
The peptide’s form is one of the most important storage factors. Lyophilised peptides are freeze-dried materials with much of the water removed. This dry form is often more stable than a liquid preparation because lower water con…
