Compound spotlight: six shared compounds, package by package
Both vendors list these compounds in different container sizes, and the normalized figures use the cheapest in-stock package per compound. Certificate examples below are the reports named in the current review notes; where no report is named, the archive figures in the certificate section are the control. PeptidePrices does not compute listing-level exact-match counts for Peptide Crafters.
GLP-3R: Disguised Alpha is 8% lower before the code
Peptide Crafters lists five containers, from 10 mg at $80.00 to 65 mg at $295.00. Disguised Alpha lists five, from 5 mg at $49.99 to 60 mg at $249.99. Normalized, Peptide Crafters is $45.38 per 10 mg and Disguised Alpha $41.67, an 8% gap before codes; peptidep takes Disguised Alpha to $37.50. Disguised Alpha's 10 mg report COA-2026-955995 prints 99.89% purity and 10.26 mg content.
GLP-2T: Peptide Crafters is 29% lower and holds the lead after the code
Peptide Crafters lists six containers, 10 mg at $70.00 through 120 mg at $270.00. Disguised Alpha lists three, 10 mg at $69.99 through 60 mg at $189.99. Normalized, Peptide Crafters is $22.50 per 10 mg against $31.67, or 29% less; peptidep brings Disguised Alpha to $28.50 and Peptide Crafters stays ahead. Disguised Alpha's 60 mg report COA-2026-954035 prints 99.93% purity and 64.13 mg content.
GLP-1S: Disguised Alpha is 42% lower, the widest of the three GLP lines
Peptide Crafters lists 5 mg at $50.00, 10 mg at $80.00 and 20 mg at $115.00. Disguised Alpha lists 10 mg at $59.99 and 30 mg at $99.99. Normalized, the figures are $57.50 against $33.33 per 10 mg, a 42% gap before codes and the widest of the three GLP lines; peptidep brings Disguised Alpha to $30.00. Disguised Alpha's 10 mg report COA-2026-MWYVF0 prints 99.82% purity and 10.64 mg content.
BPC-157: Peptide Crafters is 9% lower before the code, Disguised Alpha after
Both list a 10 mg container, at $50.00 and $54.99, and Disguised Alpha also lists 5 mg at $34.99. Peptide Crafters is 9% lower before codes at $50.00 against $54.99 per 10 mg; peptidep brings Disguised Alpha to $49.49 and reverses the line. Disguised Alpha's 10 mg report COA-2026-JFQBRV prints 99.79% to 99.93% purity and 10.35 to 10.49 mg content across two official samples. The BPC-157 compound page tracks both listings.
TB-500: an 8% Peptide Crafters lead that peptidep erases
Both list a 10 mg container. Peptide Crafters charges $60.00 and Disguised Alpha $64.99, so Peptide Crafters is 8% lower before codes. With peptidep, Disguised Alpha lands at $58.49 and takes the line.
GHK-Cu: the widest gap in the shared table
Peptide Crafters lists 100 mg and 1000 mg, both at $45.00. Disguised Alpha lists 100 mg at $44.99. Normalized, that is $0.45 per 10 mg at Peptide Crafters against $4.50 at Disguised Alpha, or 90% less before codes; peptidep moves Disguised Alpha to $4.05.
The rest of the price picture: 27 of 41 after peptidep
41 compounds are in stock at both vendors, and all 41 have a normalized price on both sides. Peptide Crafters is lower on 30 before codes and 27 after; Disguised Alpha is lower on 11 and then 14. One standard amount of every comparable compound costs $1754.24 at Peptide Crafters against $2084.05 before codes, or $1875.64 after peptidep. Peptide Crafters has no reader code, so its total does not move. The table keeps 12 of the 41 lines; the cheaper vendor is not cheaper on every line.

Breadth favors Disguised Alpha
Peptide Crafters lists 61 in-stock listings across 49 compounds; Disguised Alpha lists 80 across 65. Eight compounds are only at Peptide Crafters, including CJC-1295 (With DAC), Cartalax, Prostamax and Testagen. Twenty-four are only at Disguised Alpha, including AOD-9604, Glutathione, HCG (Human Chorionic Gonadotropin), HGH Fragment 176-191, Mazdutide and Oxytocin.
Certificates: a longer archive at Peptide Crafters, a cleaner verification trail at Disguised Alpha
Peptide Crafters publishes 636 distinct reports across 48 compounds, dated June 2023 to October 2026 and held in 981 source-version records. Eight laboratories appear, led by Janoshik (198), Pharmetric Laboratory (197) and Vanguard Laboratory (186). 226 of the 636 match the laboratory's own record (198 Janoshik, 27 Accumark, 1 TrustPointe). Another 399 come from laboratories without a usable public verifier: Vanguard 186, Pharmetric 197, MZ Biolabs 10 and Prime Analytical 6. Seven Chromate reports stay unresolved, and 4 could not be matched.
Endotoxin appears on 230 reports, microbial testing on 129 and sterility on 61. Heavy metals and fentanyl screening appear on none. Exact certificates cover 56 of 65 offers: 22 are issuer-matched, 10 Vanguard reports show as a neutral View COA, 22 Pharmetric endotoxin reports show the same way, and 2 Chromate reports stay unresolved. 27 cards show an endotoxin or microbial report because no identity-and-purity report exists for that lot. Reported purity runs 98.18% to 100% across 445 in-scope report records.
Disguised Alpha holds 329 complete reports across 501 pages: 159 from ILS Laboratories, 159 from Chromate and 11 from Freedom Diagnostics. 309 meet the laboratory-match and vendor-attribution checks. 193 eligible reports cover 83 exact strengths across 67 compounds in the 94-offer catalog, and each product-row certificate matches its compound, strength, unit and formulation. 238 reports include identity, numerical purity and measured content together; purity appears on 248 and spans 86.307% to greater than 99.98%. Extended panels cover heavy metals on 142, endotoxin on 146, fentanyl on 151, microbial on 100 and sterility on 27. Reports run November 2, 2025 to October 5, 2026. 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).
Finnrick gives Peptide Crafters a separate read: 61% and 39 passes in 60 classifiable samples, with per-compound scores from GLP-1S at 81% (10 tests) and GLP-3R at 78% down to BPC-157 at 48% (11 tests), TB-500 at 47% and CJC-1295 at 29%. Finnrick lists zero tests and no independent rating for Disguised Alpha. Trustpilot showed 4.4/5 from 44 reviews for Peptide Crafters on October 15, 2026, and 4.3/5 from 144 reviews for the linked historic Disguised Research profile on October 14, 2026.
Disclosure is partial at both. Peptide Crafters names no legal entity, founder, street address, phone number or synthesis facility, and its storefront, policies and prices require a free account login. Disguised Alpha publishes a support address but no named owner or independently verified legal operator. Neither discloses a founding year. Both archives are indexed in the COA library; scoring detail is in the Peptide Crafters review and the Disguised Alpha review.
Codes: peptidep at Disguised Alpha, no reader code at Peptide Crafters
Disguised Alpha carries peptidep for 10% off. PeptidePrices verified the code on October 15, 2026, and it auto-applies at checkout. Terms and checkout steps are on the Disguised Alpha coupon page. Peptide Crafters has no PeptidePrices reader code, so its column in the table is the same before and after. The code is real but not decisive: 27 of the 41 shared compounds remain cheaper at Peptide Crafters after it, and the basket falls from $2084.05 to $1875.64 rather than below $1754.24.
Shipping and payment: $12.50 against $13.99, both free over $250
Peptide Crafters ships to the United States, with other destinations requiring confirmation, and takes credit/debit cards. An October 15, 2026 Massachusetts checkout quoted FedEx at $12.50; a $315 basket qualified for free FedEx 2nd Day Air, and free shipping is advertised over $250. Insurance is preselected, quantity discounts run 5% to 20% for two or more containers, and returns need an RMA within 60 days with original shipping and a $25 fee deducted. Dispatch wording conflicts between an end-of-day cutoff and noon Central, and the opened-product policy is inconsistent.
Disguised Alpha ships from Irvine, California to the United States and selected international destinations. It takes Visa and American Express, Apple Pay with those brands, instant bank payment, Zelle, Chime and cryptocurrency. FedEx 2Day is $13.99 and free over $250; USPS Priority is $15.99 for PO Box, APO and PR addresses; UPS overnight is $44.99 at a Massachusetts checkout. Same-day dispatch is stated before 2:30 p.m. Pacific on weekdays or noon Saturday, international cards are excluded, damaged or incorrect deliveries must be reported within 48 hours, and shipped research products are generally final sale. Payment discounts are 5% off bank payment, Zelle and Chime and 7% off crypto; the price table does not include them.
