The evidence ladder
Every claim on this site is placed on a five-level ladder so you can see how much is actually known—not just what sounds promising.
Visual evidence ladder
- Level 1
Laboratory Research
Observed in cells, tissue, or computational models only.
- Level 2
Animal Research
Studied in animal models; results often do not transfer to people.
- Level 3
Early Human Research
Small, early-stage or uncontrolled studies in humans.
- Level 4
Controlled Human Studies
Randomised or otherwise controlled human trials exist.
- Level 5
Regulatory Review or Established Clinical Use
Reviewed by a regulator or established in clinical practice for a specific use.
Visual Reconstitution & Concentration Calculator
Container ÷ diluent = concentration → measurement. We provide the math. You provide the amounts.

The graphic is synchronized to the exact result; physical graduations may still limit practical readability.
10 mg ÷ 2 mL = 5 mg/mL → 250 mcg = 0.05 mL = 5 units
“Math verified” means the internal arithmetic is consistent. It does not imply medical approval, purity, safety or external verification.

- 1.10 mg ÷ 2 mL = 5 mg/mL
- 2.250 mcg ÷ 1,000 = 0.25 mg
- 3.0.25 mg ÷ 5 mg/mL = 0.05 mL

What is currently known about BPC-157 and tendon healing?
Most published work on BPC-157 and tendon tissue comes from animal models, where researchers have reported changes in repair markers. Controlled human studies on this specific outcome are not currently available, so conclusions about people cannot be drawn from the existing literature.
