Why combine BPC-157 with TB-500?
BPC-157 and TB-500 work through completely independent mechanisms — VEGFR2 angiogenesis and G-actin sequestering respectively. Because they do not compete for the same receptors or pathways, the full dose effect of each is maintained when combined. This produces synergistic tissue repair that neither can achieve alone.
What does the 7x GHR upregulation mean?
Growth hormone receptor (GHR) density on tendon tissue increases 7-fold at Day 3 of BPC-157 treatment in animal models. This sensitizes the tissue to growth hormone signaling, dramatically amplifying the anabolic and repair response beyond what GH alone can achieve.
Why was no LD50 found for either compound?
In standard acute toxicity studies, researchers progressively increase dosage until they find the lethal dose for 50% of subjects (LD50). For both BPC-157 and TB-500, no lethal dose was found at any tested amount. This unusually favorable safety profile reflects their endogenous origins.
What is the reconstitution protocol?
Add bacteriostatic water slowly to the lyophilized powder — do not inject water directly onto the powder, allow it to run down the side of the vial. Do not shake — gently swirl until dissolved. Store reconstituted at 2-8°C for up to 30 days. Do not freeze after reconstitution.
Is this combination prohibited in competitive sport?
Yes. Both BPC-157 and TB-500 are prohibited by WADA under category S0 (non-approved substances). This applies in-competition and out-of-competition. This product is for research use only.
What tissues have been studied?
Both compounds have been studied across tendon, muscle, bone, cardiac, neural, gastrointestinal, and skin tissue types. TB-500 has completed Phase 1 human data. BPC-157 has extensive preclinical data across all major tissue types.
