Quality & sourcing: Peptides vary in purity, potency, and sterility
Other peptides like KPV and BPC-157 are available as research compounds in many jurisdictions
PMC6073405 BPC-157 angiogenic signaling VEGFR2-Akt-eNOS activation, nitric oxide bioavailability, FAK-paxillin cell-anchoring cascade, anti-cytokine modulation: PMC8275860 TB-4 / TB-500 G-actin sequestration and threshold-saturation mechanism actin-monomer binding, cytoskeletal mobilization for cell migration, mass-action pharmacodynamics requiring bolus dosing: PubMed 12581423 TB-4 Ac-SDKP anti-fibrotic fragment N-terminal tetrapeptide (fragment 14) released by meprin- and POP processing
Self-administration of research peptides carries inherent risks including contamination, incorrect dosing, and unknown long-term effects
So if somebody comes to us saying I want to get fitter, lift heavier, get bigger muscle, I will still recommend BPC-157, even though it doesnt directly affect any of those things
GHK-Cu is predominantly found in saliva, blood, and urine, and has multiple biological actions when administered to test subjects, including [1]: Antioxidant gene activity [2] Suppression of inflammatory cytokine interleukin-6 [2] Increased protein accumulation [3] Increased collagen synthesis [3] In animal models, GHK-Cu has been shown to increase an anti-inflammatory proteogly called decorin that can protect diabetic rats from kidney-damaging fibrosis [2, 4]
