Alpha Peptides (alpha-peptides.io) is a U.S.-based, East Coast research supplier with a peptide-forward catalog of 30+ compounds — a deep growth-hormone bench alongside GLP-class metabolic research, recovery blends, longevity, cognitive, sleep, and reproductive-health compounds. What it leads on is verifiable testing: Alpha files its Certificates of Analysis by lot on a public COA page, from two named laboratories — Freedom Diagnostics for its 2025 lots and Analytical Formulations, Inc. for its 2026 lots. Popular compounds by research area:

Metabolic & GLP-1
Retatrutide (GLP-3 RT), Tirzepatide (GLP-2 TZ), Semaglutide (GLP-1 SM), Cagrilintide, MOTS-C, AOD-9604, 5-Amino-1MQ
Recovery & Tissue Repair
BPC-157, TB-500, a blend of BPC-157 and TB-500, KPV
Growth Hormone
CJC-1295 (with & without DAC), Ipamorelin, Sermorelin, Tesamorelin, GHRP-2, GHRP-6, Hexarelin, IGF-1 LR3, IGF-1 DES, MGF, Follistatin-344
Cognitive & Nootropic
Semax, Selank, Adamax
Skin Health & Anti-Aging
GHK-Cu, GLOW, KLOW, Melanotan I, Melanotan II
Immune & Signaling
Thymosin Alpha-1, VIP, LL-37, Cibinetide (ARA-290)
Sleep & Recovery
DSIP
Longevity
Glutathione, Epitalon, NAD+, SS-31
Bioregulators
Pinealon
Sexual & Reproductive Health
PT-141, Oxytocin, Kisspeptin-10

The certificates on Alpha's COA page come from two laboratories. Its 2025 lots carry Freedom Diagnostics reports: purity by HPLC with UV detection, identity by mass spectrometry and net peptide content, each with a search code that resolves on Freedom's own site rather than Alpha's. Its 2026 lots carry Analytical Formulations, Inc. summary reports, three of them served from the laboratory's own storage rather than copied by Alpha; those test by UV/Vis spectrophotometry — identity by a λmax match against a reference standard, a percent-purity figure, a quantitative assay in mg per vial, and combined heavy metals — rather than by HPLC or mass spectrometry. Alpha states that its bulk material is sourced from cGMP-aligned manufacturing partners, and that its standard is a 99.0% purity floor, with lots below it rejected rather than discounted or relabeled.

The distinguishing feature is verifiability: Certificates of Analysis are published on a public COA page and filed by lot, so a researcher can check identity and purity at the batch level before use. Vials are lyophilized, foil-sealed, and shipped cold-chain from the East Coast; fulfillment is U.S.-only, typically same or next business day.

Finnrick rates Alpha Peptides 75% across 1 test (read 30 September 2026) — a pass rate across those tests, weighted so that newer tests count for more, not a purity figure.

One note worth flagging: several copycat sites imitate this brand. alpha-peptides.io is the authoritative store, and the Shop button below links to it directly — enter code PROFPEPTIDE there to apply the discount.

Is Alpha Peptides third-party tested?
Yes, by two laboratories, each named on the certificates linked from Alpha's own COA page. Its 2025 lots carry Freedom Diagnostics reports — purity by HPLC with UV detection, identity by mass spectrometry and net peptide content — each with a search code that resolves on Freedom's own site; Prof. Peptide re-checked three there on October 11, 2026. Its 2026 lots carry Analytical Formulations, Inc. summary reports, three of them served from the laboratory's own storage, which test by UV/Vis spectrophotometry: identity by a lambda-max match, a percent-purity figure, a quantitative assay in mg per vial, and combined heavy metals. Alpha states a 99.0% purity floor and says lots below it are rejected.
How can I verify an Alpha Peptides product?
Alpha Peptides publishes Certificates of Analysis on a public COA page and files a COA against every lot before it ships, so a researcher can match the specific batch they received to its test documentation before use.
