BPC-157 Acetate / TB-500 Fragment 17-23 Blend
Also known as: BPC-157 Acetate + TB-500 Fragment 17-23 Blend
A research blend pairing the cytoprotective peptide BPC-157 with the actin-binding fragment 17-23 of Thymosin Beta-4 (TB-500). It is studied for soft-tissue repair, angiogenesis, and recovery.

Mechanism of Action
BPC-157 accelerates healing by upregulating VEGFR2-driven angiogenesis, activating the nitric oxide system, and enhancing fibroblast migration and growth-factor receptor expression in tendon, muscle, and gut tissue. The TB-500 fragment 17-23 contains the LKKTETQ actin-binding motif of Thymosin Beta-4, the active region responsible for promoting actin polymerization, cell migration, and angiogenesis while reducing inflammation. Delivering this short fragment focuses activity on the cytoskeletal-remodeling component of the parent peptide. The two agents target distinct but complementary phases of tissue regeneration.
- Half-life
- Short for BPC-157 (minutes to a few hours); the short TB-4 fragment is cleared rapidly on a similar timescale.
- Administration Routes
- subcutaneous
- Research Status
- Research Chemical
Reported Benefits
- Studied for accelerated tendon, ligament, and muscle repair
- Promotes angiogenesis and microvascular regrowth
- Supports cell migration and cytoskeletal remodeling
- May reduce inflammation at injury sites
- Combines systemic cytoprotection with actin-binding repair signals
- Explored for faster post-training recovery
Potential Side Effects
- Injection-site redness or swelling
- Lightheadedness or fatigue
- Possible headache
- Unknown effects from combining components
- Limited human safety data
Common Dosing
For research use only and not medical advice; component literature describes BPC-157 in the ~250-500 mcg range one to two times daily and Thymosin Beta-4 fragments in the low-milligram weekly range. The blend lacks a standardized protocol.
The dosing information above is aggregated from research literature and anecdotal community reports for educational purposes only. It is not a recommendation, prescription, or medical advice. Peptides are sold as research chemicals only and are not intended for human use.
Contraindications
- Active or suspected malignancy due to pro-angiogenic activity
- Pregnancy and breastfeeding
- Known hypersensitivity to any blend component
BPC-157
A synthetic peptide fragment derived from a protein found in gastric juice, studied for its broad tissue-healing and cytoprotective effects. Popular in research for tendon, ligament, muscle, and gut repair.
TB-500
A synthetic version of the active region of Thymosin Beta-4, a naturally occurring peptide that regulates cell migration and tissue repair. Researched for recovery, flexibility, and wound healing.
TB-500 Fragment (17-23)
TB-500 Fragment 17-23 is a short peptide corresponding to the actin-binding region of thymosin beta-4, studied for tissue repair and regeneration. It represents the core bioactive sequence often credited with TB-500's healing effects.
GHK (Basic) (Tripeptide-1)
GHK is a naturally occurring human tripeptide (glycyl-L-histidyl-L-lysine) studied for skin remodeling, wound healing, and tissue regeneration. The copper-free 'basic' form is the parent peptide that readily binds copper in tissue.
GHK-Cu
A naturally occurring copper-binding tripeptide (glycyl-L-histidyl-L-lysine) widely researched for skin regeneration, collagen synthesis, and wound healing. Common in topical cosmetics.
