Compounds studied for bone & connective, ranked by the strength of the evidence — strongest at the top, research-grade and disappointing below. Grades reflect the evidence, not marketing. This is a neutral reference; nothing here is a recommendation to use, and no compound is offered for sale.
BPC-157 is a synthetic 15-amino-acid peptide derived from a protein found in gastric juice, studied chiefly in animal models for effects on tissue repair — the gastrointestinal…
the "Wolverine Stack" is the popular nickname (after the self-healing Marvel character) for combining two research peptides — BPC-157 (#11) and TB-500 (#12) — for injury and…
ACE-031 (ramatercept) is a soluble activin-receptor-IIB fusion protein — a decoy that mops up myostatin, activin A and GDF-11 to release the brakes on muscle.
Apelin is an endogenous peptide and the natural ligand of the APJ receptor, a G-protein-coupled receptor closely related to the angiotensin II receptor.
B7-33 is a designed single-chain peptide derived from the B-chain of H2 relaxin, built to keep relaxin's anti-fibrotic activity while shedding the difficulties of the full…
Follistatin is a natural myostatin inhibitor whose biology is spectacular — releasing the body's brake on muscle produces the "double-muscling" seen across species.
IGF-1 LR3 is a long-acting engineered version of IGF-1, prized in the muscle community for one genuinely special property — hyperplasia, the formation of new muscle fibres via…
Ranking is by evidence grade (A–F), the same ceiling shown on each compound page — not by popularity or margin. No dosing, reconstitution, or administration is given anywhere on Vallydia. See each entry for its full evidence table and legal status by region.
