Sports Technology Labs

Why we recommend Sports Technology Labs

Sports Technology Labs (STL) launched in 2017 as a SARMs vendor and has been expanding into research peptides under the same compliance framework that built its reputation in the SARM market. Note: our registry audit confirms that the peptide catalog is comparatively newer than the core SARMs offering — a disclosure we make transparently so readers can weight the track record accordingly. Testing score: 6.0 out of 7. Discount code STL10 gives 10% off. We evaluate STL against Pepticker's 7-criterion methodology (https://pepticker.com/methodology); the recommended verdict reflects its institutional compliance culture and HPLC documentation, tempered by the newer peptide-specific track record.

Testing & COA practices

HPLC purity testing is documented for the peptide catalog. The transition matters: vendors that built their testing culture in SARMs — a category with its own analytical demands — tend to apply those habits to new catalog categories rather than reinventing QC from scratch. The HPLC standard applied to peptides follows the same quality floor STL established in its original category. COA links were confirmed active as of our April 2026 verification. No mass-spec identity, endotoxin, or sterility testing is documented for the peptide catalog.

Shipping, quality, and customer service

Shipping is $9.95 domestic flat — standard for tier-2 US vendors. STL's nine-year operating history means its customer service infrastructure is more developed than newer vendors; its established processes for handling disputes, refunds, and reships predate its peptide expansion. For researchers who are already STL customers for SARMs, the vendor relationship and customer service model are known quantities. Quality signals in the peptide segment are consistent with the HPLC documentation, but researchers should confirm SKU-level COA availability before ordering less-common peptides.

Product range and pricing

The catalog covers research peptides across multiple categories. For researchers who also purchase SARMs or other research compounds, STL's multi-category presence means one vendor relationship covers more of the research stack. Pricing is mid-tier, consistent with HPLC-verified US vendors.

Where they fall short

The peptide catalog is newer and carries less community feedback than the established SARM offering. Single-panel HPLC means no mass-spec identity confirmation. No endotoxin or sterility testing documented for peptides. The SARMs-origin context is relevant: researchers evaluating STL purely for peptides are assessing a product line that hasn't accumulated the same depth of community validation as its legacy category.

Bottom line

Sports Technology Labs earns its recommended verdict through institutional compliance culture and nine years of uninterrupted operations — two signals that transfer meaningfully from its SARM origins to the peptide category. It's particularly well-suited for researchers who are already STL customers for SARMs and want to consolidate sourcing. For peptide-only buyers without that context, Core Peptides or Peptide Warehouse may be easier first choices. See our full methodology at https://pepticker.com/methodology. Use code STL10.
