Angiogenesis & cytoprotection
One of 5 mechanistic pathways to 🩹 Heal an injury · 8 options
Tendon and ligament heal slowly because blood supply is sparse. Compounds that trigger new vessel growth into the injured area are arguing they can fix the rate-limiting step rather than the repair itself — which, if true, changes the timeline more than any anti-inflammatory can.
Healing that stalls usually has a systemic reason. Raised HbA1c impairs the microvasculature the whole pathway depends on, and vitamin D deficiency measurably slows tissue repair.

What engages this pathway
Ordered by how directly each one acts on the mechanism above — never by how much trial evidence exists. Each links to its full breakdown with dosing, half-life and vendor.
💉 BPC-157 (inj/oral)
Upregulates VEGF and the growth-hormone receptor in tendon fibroblasts, and activates the FAK-paxillin pathway. In rat models it accelerates healing of transected tendon, ligament, muscle and gut. The rodent evidence is broad, consistent and genuinely impressive; the human trials do not exist, and that gap is the honest headline.
💉 TB-500
Thymosin β4 sequesters G-actin, enabling cell migration into the wound bed, and independently promotes angiogenesis. Systemic rather than local, which is why it's the choice when the injury is diffuse or you can't localise it.
💉 Wolverine Blend
BPC-157 and TB-500 combined — the local-repair and systemic-migration arguments in one vial. Popular because the two mechanisms genuinely don't overlap.
💉 GHK-Cu (inj/oral)
A copper-carrier tripeptide that stimulates angiogenesis, collagen and glycosaminoglycan synthesis, and upregulates antioxidant enzymes. It has decent wound-healing evidence topically; the systemic injection case is extrapolated from that.
💉 Actovegin
Improves cellular oxygen and glucose uptake. Used widely in European sports medicine for muscle injury with mixed trial results and an unidentified active fraction.
💉 ARA-290
Targets the innate repair receptor — the tissue-protective arm of EPO signalling — without raising haematocrit. Human trials in small-fibre neuropathy show benefit; the musculoskeletal extrapolation is untested.
💉 Pentosan Polysulfate
A semi-synthetic glycosaminoglycan. Approved for interstitial cystitis and used in veterinary joint medicine; the maculopathy risk with long-term use is well documented and often missed.
💉 GLP-2
Intestinotrophic — drives crypt-cell proliferation and mucosal growth specifically in the gut. The teduglutide analog is approved for short-bowel syndrome, which is real proof the mechanism works in humans.

Frequently asked questions
Tendon and ligament heal slowly because blood supply is sparse. Compounds that trigger new vessel growth into the injured area are arguing they can fix the rate-limiting step rather than the repair itself — which, if true, changes the timeline more than any anti-inflammatory can.
8 options are mapped to this pathway in the Vault, including BPC-157 (inj/oral), TB-500, Wolverine Blend, GHK-Cu (inj/oral). They are grouped by the mechanism they act through rather than ranked by how much trial evidence exists — 2 carry clinical validation and 5 are mechanistic predictions.
Healing that stalls usually has a systemic reason. Raised HbA1c impairs the microvasculature the whole pathway depends on, and vitamin D deficiency measurably slows tissue repair. The markers worth checking are hs-CRP (High-Sensitivity C-Reactive Protein), ESR (Sed Rate), Vitamin D (25-Hydroxy), HbA1c (Hemoglobin A1c).
Unproven is not the same as ineffective. Of the 8 options on this pathway, 2 have clinical validation and 5 are graded theoretical — meaning the mechanism is sound but the specific human trial has not been run, which is true of a great deal of what works in this space. Nothing on this page is ordered by evidence tier, because sorting by trial count would bury the compounds you came looking for.
