Best peptides for muscle growth
Best peptides for muscle growth: what each compound does, and which vendors sell it pure. Muscle-focused peptides mostly work upstream: rather than acting on muscle directly, they signal the pituitary to release more of your own growth hormone. They differ in half-life, pulse shape and dosing burden. Each is ranked below by lab-verified purity and price per milligram.

Purity is the mean lab score across every vendor we have tested for that peptide, out of 10. Most vendors score in the 9s, so the number separates them where the letter grade does not. Prices update as catalogs are re-scraped.

How this ranking is put together
Nothing on this page is a recommendation to take anything. It is a ranking of what independent labs found inside the vial, and what each vendor charges for it.
- 1
Start with the source record
Check the sample source, batch and test date on each published record. Sampling methods vary, and a result applies to the sample tested.
- 2
An independent lab runs them
Third-party HPLC and mass-spec testing measures what is actually in the vial against what the label claims.
- 3
Every result is published
Pass or fail, the certificate is linked from the vendor's page. The purity grade above is the average across all of them.
- 4
Prices are tracked separately
Vendor catalogs are re-scraped on a schedule and normalised to price per milligram, so multipacks and vial sizes compare honestly.
Common questions
- Which muscle-growth peptide has the most vendor coverage?
- Tesamorelin, carried by 144 vendors in our index with 723 published lab tests. Wider coverage means more price competition, not that it is the right compound for you.
- What do muscle-growth peptides cost?
- Prices are compared per milligram so vial sizes and multipacks are directly comparable. The cheapest verified listing in this category is currently $2.15 / mg for Tesamorelin. Live prices are on each peptide's page.
- How do you decide which peptides belong in this category?
- A peptide appears here when published research studies it for this outcome. Peptides often belong to several categories — a compound studied for wound healing may also appear under skin or gut health. In this category that includes Tesamorelin, Sermorelin, Ipamorelin.
- Is Peptide Vendor Reviews selling these peptides?
- No. We do not sell peptides. We buy samples, publish independent lab results, and track vendor prices. Some vendor links are affiliate links, which never affects a purity score or a ranking position.
