Combining with other peptides GHK-Cu often appears in protocols alongside BPC-157 , TB-500 , and other peptides
BPC 157 can be very useful in gut repair to return the gut to good health, as it protects cells and organs (Sikiric P, 2017)

Sleep and recovery: Deeper, more restorative sleep becomes a reliable pattern rather than an occasional effect Post-exercise recovery improves less soreness, faster return to baseline Minor soft tissue aches (old nagging injuries) may begin to feel better Body composition (early signals): Skin quality begins to improve increased hydration and elasticity from GH-driven collagen synthesis Subtle reduction in subcutaneous water retention, particularly around the midsection Appetite patterns shift some users report increased hunger (GH is a counterregulatory hormone), others report better appetite regulation Energy and mood: More consistent energy levels through the day Improved sense of well-being GH influences neurotransmitter function and this often manifests as a subtle mood elevation DAC vs no-DAC difference: By week 2-4, DAC users on a 1-2x/week schedule have accumulated sustained IGF-1 elevation

It is worth noting that the expression of claudin-2 has a dual effect: under normal conditions, it participates in ion transport, but its overexpression in inflammatory states may lead to a leaky barrier [72]
