BPC-157 vs TB-500: Comparison and Stacking

This is the comparison we get asked about most in the recovery category. Both BPC-157 and TB-500 are "healing peptides." Both get recommended for injuries. But they do very different things at the cellular level, and knowing which does what helps you pick the right one (or decide to run both).

BPC-157: the vascular builder

[[BPC-157|22]] comes from gastric juice. Its primary mechanism: VEGF upregulation (grows new blood vessels toward injuries), nitric oxide modulation (controls blood flow and inflammation), and growth factor stimulation (EGF, FGF). It excels at gut protection, tendon/ligament healing, and wound repair.

Think of BPC-157 as the infrastructure crew. It builds the roads (blood vessels) that deliver supplies to the construction site.

Best for: NSAID gut damage, tendon injuries, ligament tears, general wound healing. Dosed locally (near the injury) at 250-500mcg/day subcutaneously.

TB-500: the cell dispatcher

[[TB-500|25]] is based on Thymosin Beta-4. Its primary mechanism: actin upregulation (moves repair cells to injury sites), anti-inflammatory cytokine modulation, and tissue remodeling support. It excels at chronic inflammation, cardiac tissue support, and situations where cells aren't reaching damaged areas fast enough.

Think of TB-500 as the dispatch team. It sends the repair crews down those roads.

Best for: chronic inflammation, post-injury recovery, general tissue repair, hair follicle activation. Dosed systemically (injection site doesn't matter) at 2-5mg twice weekly.

Key differences

• Mechanism: BPC-157 = angiogenesis + gut protection. TB-500 = cell migration + anti-inflammation.
• Injection: BPC-157 works best near the injury. TB-500 works systemically from any injection site.
• Dosing: BPC-157 daily (250-500mcg). TB-500 twice weekly (2-5mg).
• Gut focus: BPC-157 has strong GI data. TB-500 doesn't specifically target the gut.
• Inflammation: TB-500 has stronger direct anti-inflammatory effects. BPC-157 modulates inflammation indirectly through NO.

When to stack them

For serious injuries or chronic problems, running both covers the full repair cascade: BPC-157 builds blood supply to the area, TB-500 delivers the cells and controls the inflammatory environment. They're complementary, not redundant.

This synergy is exactly why [[GLOW|23]] and [[KLOW|20]] contain both. GLOW adds GHK-Cu for collagen (skin focus). KLOW adds KPV for scalp inflammation (hair focus).

If you want the flexibility to dose each separately, run [[BPC-157|22]] + [[TB-500|25]] individually. If you want a pre-configured blend, pick GLOW or KLOW based on your target area.
