Repair and Recovery Blend (Stable BPC-157 Arginate, TB-4 Fragment)
Also known as: Repair and Recovery Blend, Healing and Repair Research Blend (BPC-157, TB4 Frag 1-4, GHK-Cu)
A research blend pairing a stabilized arginate salt of BPC-157 with an active fragment of Thymosin Beta-4 to target soft-tissue and musculoskeletal repair. It is studied for accelerated wound healing and recovery.

Mechanism of Action
BPC-157 promotes angiogenesis and tendon/ligament fibroblast outgrowth by upregulating VEGFR2 signaling, the nitric oxide system, and growth-factor receptor expression. The arginate salt form is intended to improve stability and solubility relative to the acetate. The Thymosin Beta-4 N-terminal fragment retains the actin-binding and cell-migration-promoting properties of the parent peptide, supporting cytoskeletal remodeling, keratinocyte and endothelial migration, and reduced inflammation. Together the components target the angiogenic, migratory, and anti-inflammatory phases of healing.
- Half-life
- Short for BPC-157 (minutes to a few hours in plasma); the TB-4 fragment is cleared on a similar short timescale.
- Administration Routes
- subcutaneous
- Research Status
- Research Chemical
Reported Benefits
- Studied for accelerated tendon, ligament, and muscle repair
- Promotes angiogenesis and new tissue formation
- May support cell migration during wound healing
- Explored for reduced inflammation around injury sites
- Combines two complementary regenerative peptides
- Investigated for faster recovery between training bouts
Potential Side Effects
- Injection-site redness, swelling, or discomfort
- Lightheadedness or transient fatigue
- Possible headache
- Unknown effects from combining components
- Sparse 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. Blend products vary by vendor and have no 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 (1-4)
TB-500 Fragment 1-4 is the N-terminal tetrapeptide (Ac-SDKP) of thymosin beta-4, studied for anti-fibrotic and tissue-protective effects. This fragment is distinct from the actin-binding region and is associated with regulation of fibrosis and inflammation.
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.
