Running Sermorelin + GHK-Cu + BPC-157. They target different things, so here’s the jist of what each one is for:
Sermorelin — GH / IGF-1 / body composition
Sermorelin is a GHRH analogue. It binds to GHRH receptors in the pituitary and basically signals your body to release more of its own growth hormone. That increased GH can then increase downstream IGF-1 signaling.
Main targets:
GHK-Cu — skin / collagen / hair
GHK-Cu is a copper peptide that’s mainly interesting for skin and tissue remodeling. It affects fibroblast activity, collagen production, extracellular-matrix remodeling, and other repair pathways.
Main targets:
BPC-157 — recovery / connective tissue
BPC-157 is mainly used with recovery in mind. It interacts with pathways involving nitric oxide, angiogenesis, fibroblasts, and tissue repair.
Main targets:
So basically:
Sermorelin = GH/body composition
GHK-Cu = skin/collagen
BPC-157 = recovery/connective tissue
Near perfect starting peptide combo
Relatively safe during puberty
Sermorelin — GH / IGF-1 / body composition
Sermorelin is a GHRH analogue. It binds to GHRH receptors in the pituitary and basically signals your body to release more of its own growth hormone. That increased GH can then increase downstream IGF-1 signaling.
Main targets:
- GH/IGF-1 pathway
- Body composition
- Protein/fat metabolism
- Recovery and tissue turnover
GHK-Cu — skin / collagen / hair
GHK-Cu is a copper peptide that’s mainly interesting for skin and tissue remodeling. It affects fibroblast activity, collagen production, extracellular-matrix remodeling, and other repair pathways.
Main targets:
- Collagen + elastin
- Skin quality
- Tissue remodeling/repair
- Hair/skin applications
BPC-157 — recovery / connective tissue
BPC-157 is mainly used with recovery in mind. It interacts with pathways involving nitric oxide, angiogenesis, fibroblasts, and tissue repair.
Main targets:
- Tendons/ligaments
- Muscle and connective-tissue recovery
- Blood-vessel formation
- General tissue repair
So basically:
Sermorelin = GH/body composition
GHK-Cu = skin/collagen
BPC-157 = recovery/connective tissue
Near perfect starting peptide combo
Relatively safe during puberty
