What to Check Before Choosing Another Supplier
Compare the same product
Start with the exact compound, formulation and labeled quantity. A BPC-157/TB-500 blend is different from BPC-157 alone. A pre-mixed solution also needs a different comparison from a powder vial.
Read the batch report
Open the Certificate of Analysis instead of relying on a “lab tested” badge. Check the lot number, laboratory, test date and methods.
Work out the price per mg
Divide the discounted product price by the total labeled milligrams.
For example, a 10 mg vial priced at $40 costs $4 per mg before shipping and tax. Use the same calculation for each matching listing, a bigger discount does not always mean a better price.
Check shipping and support
Confirm that the vendor serves your location. Check shipping charges, dispatch estimates.
Why Did Strate Labs Shut Down?
“Strate Labs says changes in the regulatory landscape led to its closure. The company also faced an Eli Lilly–initiated USITC investigation involving tirzepatide, a default finding in May 2024 and a cease-and-desist order in April 2025. Its closure notice does not say that this case directly caused the shutdown.”
