Compound spotlight: the rows behind the 17-to-11 split
Prices use each vendor's cheapest in-stock package per compound, normalized to the compound's standard research amount. The after-code figure applies each vendor's verified 10% reader code.
GLP-1S: Instant Peptides is 15% lower
Instant Peptides sells 10 mg for $49.95 and 30 mg for $84.95. Its cheapest package normalizes to $28.32 per 10 mg, or $25.49 after the code. Disguised Alpha sells 10 mg for $59.99 and 30 mg for $99.99, or $33.33 per 10 mg and $30.00 after its code. Instant Peptides is 15% lower before either code.
Disguised Alpha publishes COA-2026-MWYVF0 for its 10 mg GLP-1S: 99.82% purity and 10.64 mg content. The reviewed record does not isolate a GLP-1S report for Instant Peptides; coverage is the listing-level 31 of 36.
GLP-2T: Disguised Alpha is 3% lower
Instant Peptides lists 10 mg $50.00, 20 mg $90.00, 40 mg $130.00 and 60 mg $200.00. The cheapest package normalizes to $32.50 per 10 mg, or $29.25 after the code. Disguised Alpha lists 10 mg $69.99, 30 mg $119.99 and 60 mg $189.99, or $31.67 per 10 mg and $28.50 after its code. Disguised Alpha is 3% lower.
Its 60 mg report, COA-2026-954035, prints 99.93% purity and 64.13 mg content, one of 238 reports carrying identity, purity and content together. Instant Peptides' coverage is the same 31 of 36.
Sermorelin: a 40% gap on the standard amount
Instant Peptides sells 10 mg for $59.95, or $59.95 per 10 mg and $53.96 after the code. Disguised Alpha sells 5 mg for $49.99, which normalizes to $99.98 per 10 mg and $89.98 after its code. Instant Peptides is 40% lower.
Disguised Alpha's $49.99 buys 5 mg. Instant Peptides' $59.95 buys 10 mg. The normalized figure is the one to compare.
Wolverine: 49% lower at Disguised Alpha
Instant Peptides sells 10 mg for $78.95, or $78.95 per 10 mg and $71.06 after the code. Disguised Alpha sells 20 mg for $79.99, or $40.00 per 10 mg and $36.00 after its code. Disguised Alpha is 49% lower.
The larger package is Disguised Alpha's 20 mg vial. Its $79.99 entry price normalizes to $40.00 per 10 mg against Instant Peptides' $78.95. The reviewed record does not isolate reports for Sermorelin or Wolverine; those rows rest on the listing-level counts.

Across all 28 shared compounds, Instant Peptides is lower on 17 and Disguised Alpha on 11 before codes. The split is unchanged after the codes: Instant Peptides 17, Disguised Alpha 11.

Catalog size: 37 compounds only at Disguised Alpha
Instant Peptides lists 36 in-stock listings across 29 compounds. Disguised Alpha lists 80 across 65. They share 28. Instant Peptides carries one compound Disguised Alpha does not, Cartalax. Disguised Alpha carries 37 that Instant Peptides does not, including BPC-157, NAD+, Tesamorelin, Glutathione, GLP-3R, ARA-290 and Cerebrolysin.
The smaller catalog wins more shared price rows. The larger catalog has 37 compounds the other does not stock, which matters more than a 3% or 8% edge if your compound is on that list. BPC-157 prices.
COA depth: 329 records at Disguised Alpha, 208 at Instant Peptides
Instant Peptides retains 208 report records. PeptidePrices matched 199 of 208 to official issuer reports in the October 4, 2026 review. The archive supplied 207 complete files covering 208 report identities across 211 pages: 88 from Kovera Labs, 116 from Freedom Diagnostics and three two-page Vanguard capsule reports. Reports cover identity, purity and measured content, with contamination panels where printed. Thirty-four public PDF links returned invalid files. Two Kovera exports differ from the issuer in certification date, and one vendor copy reports 58.12 mg where the official export reports 58.46 mg. Three Freedom codes returned no document in the official lookup, and the three Vanguard reports have no specific public issuer match.
The COA library holds 208 records for Instant Peptides. 31 of 36 in-stock listings carry an exact issuer-verified certificate. Matched listings name Kovera Labs (20) and Freedom Diagnostics (11). The retained GHK-Cu 50 mg report measures 52.90 mg on average. GHK-Cu prices.
Disguised Alpha retains 329 report sets. It reports 309 as meeting the laboratory-match and vendor-attribution checks, and 193 eligible reports cover 83 exact strengths across 67 compounds in a 94-offer catalog. The library spans 329 complete reports across 501 pages: 159 from ILS Laboratories, 159 from Chromate and 11 from Freedom Diagnostics. 238 reports include identity, numerical purity and measured content together, and numerical purity appears on 248 reports, ranging from 86.307% to greater than 99.98%. Extended panels include heavy metals on 142 reports, endotoxin on 146, fentanyl screens on 151, microbial results on 100 and separately labeled sterility on 27. 65 of 80 in-stock listings carry an exact issuer-verified certificate, 53 from ILS Laboratories and 12 from Chromate. Across all 83 exact current strengths the split is ILS Laboratories (65), Chromate (16) and Freedom Diagnostics (2).
The two archives are not equivalent. Instant Peptides' 208 records include three Vanguard capsule reports that cover quantity, ICP-MS metals and USP <61> bioburden but not purity, LC-MS identity or a sterility culture. Disguised Alpha's 193 eligible reports cover 83 exact current strengths. Buffered NAD+ 500 mg and 1,000 mg remain listed without powder-report controls, and historical IGF-1 LR3 and NAD+ values below 95% remain in the archive. An archive listing does not independently establish the physical lot shipping today, so match the certificate to the exact strength before ordering. IGF-1 LR3 prices.
Both verified 10% codes, different checkout behavior
Instant Peptides uses PEPTIDEPRICES for 10% off. PeptidePrices confirmed the discount in a checkout test on October 3, 2026. The code does not auto-apply. Terms: Instant Peptides coupon code.
Disguised Alpha uses peptidep for 10% off. The offer is confirmed by PeptidePrices, checked on October 15, 2026, and applies automatically at checkout. Terms: Disguised Alpha coupon code.
