Evidence summary
Why Alpha Peptides is rated 8/10
Our conclusion
Alpha Peptides has a strong public COA program from Freedom Diagnostics and Analytical Formulations Inc. The sampled AFI report includes a rare triple-vial panel with heavy-metals screening. PeptidePrices confirmed samples from both laboratories.
The caveats are coverage and reputation. The current public library does not establish reports for every advertised compound, and Trustpilot has only three reviews. Match the exact product, strength, and lot. US-based; 10%-off code PEPTIDEPRICES10.
Verification notes
What we reviewed, with the limits of that evidence kept explicit.
01
Company & checkout
Alpha Peptides is a US-based supplier in Nashua, New Hampshire, with a strong public COA library from two named third-party laboratories. PeptidePrices verified Freedom Diagnostics and Analytical Formulations Inc. samples. The AFI sample uses triple-vial testing with identity, 99.7% purity, quantitative assay against the label claim, and heavy-metals screening below 20 ppb. The current library exposes about 18 product groups while the storefront advertises more than 30 compounds, so PeptidePrices no longer describes the testing as full-catalog coverage.
02
COA review
The named-lab, batch-level evidence is the strongest signal. Current shipping terms state 48 to 72 hours of processing and typical standard transit of five to seven business days. Trustpilot listed 3.4/5 from only three reviews; the sample is too small to establish a mature reputation or a product-quality conclusion. The prominent review for alpha-peptides.co.uk belongs to a different UK business. US-based; free shipping over $200; 10%-off reader code.

Unusually rigorous AFI panel: triple-vial sampling with identity, purity (99.7%), quantitative assay vs label claim, AND heavy-metals screening (<20 ppb) — heavy metals is rarely tested

Watch-outs
The public COA library shows about 18 product groups while the storefront advertises more than 30 compounds, so full-catalog coverage is not established
Trustpilot is a thin and mixed signal at 3.4/5 from only three reviews
The brand's operating history is shorter than the legacy vendors we track, so we continue monitoring inventory consistency and customer-service performance
