Biostrategix
Biostrategix is the budget option of the three, pairing lower TB-500 pricing with visible COA and lab-report links rather than just a purity claim.

Why these made the page
How these three compare on TB-500 specifically
Iron Peptides and Pinnacle sit at similar mid-range prices with comparable testing emphasis, so the real choice between them comes down to which supplier's broader catalog you trust more. Biostrategix undercuts both on price while still linking a lab report rather than relying on a bare purity claim.
Important limit
Editorial shortlist only
This is a site-quality comparison built around visible testing, documentation, and labeling details. Key details should still be verified directly on each supplier page.
Next step
Use TB-500 pages to narrow the field, then verify the supplier.
If TB-500 is the compound you care about most, this page helps shorten the list. After that, open the individual review or use the verifier for a more structured page check.
