Never merged into one number. Some supplier links here are referral links, marked where they appear, which pay Terminus Research when a reader buys. The same terms are open to every supplier in the ledger, apart from the one exception the referral policy page names, participation changes no score, rank, caution, or coverage decision, and a link is not an endorsement.
BulkGLP's /verified-quality/ archive is a more thorough documentation setup than most other vendors checked the same way, publishing 36 current and 13 prior batch reports across 29 products, and the current 10mg retatrutide certificate for lot 062503 checked directly against the issuing lab's own domain, coas.freedomdiagnosticstesting.com, returned a byte-for-byte match, same MD5 checksum, to the PDF BulkGLP hosts itself. That same lot number carries two conflicting readings, though: the archive's prior report for lot 062503 states net content 12.05 mg and 99.76 percent purity, while the current report for the identical lot states 11.20 mg and 99.87 percent, three weeks apart, with neither the product page nor the archive explaining the difference. Separately, the vendor's own published Freedom Diagnostics certificate for a different product, ARA-290, states 53.90 percent purity by HPLC-UV against a co-eluting methionine peak, and that product remains listed in stock at $80.00 with no flag on its own page. Has anyone who received lot 062503 checked which of the two reports, the 12.05 mg prior or the 11.20 mg current, matches the vial that actually arrived?
What the record holds
STATED WINDOW IN DAYS
“processes orders in 1 to 2 business days via USPS, UPS or FedEx”
Per /shipping-policy/ (dateline October 2, 2025): 1 to 2 business day processing via USPS, UPS or FedEx with rates calculated at checkout rather than posted as a flat table; domestic transit 3 to 5 business days Standard, 2 to 3 Expedited, 1 day Overnight where supported; also ships internationally to "select countries" with duties, taxes and customs risk on the recipient. A processing window with no same-day or next-day dispatch commitment stated, so it classes as a stated window.

Read on 2026-08-26. One reading on one day, and prices are not tracked over time here.
This supplier was not part of the Trustpilot reading of 2026-08-25, which covered 59 of the 126 suppliers on file. That is a fact about this publication's coverage, stated rather than left to be read either way.
4 claims from this publication's own dossier on this supplier were read again against the live site on 2026-08-26: 1 held, 3 corrected before publication.
A corrected claim is an error of ours that the re-read caught before it reached a page. This line tracks this publication's own accuracy. It says nothing about the supplier.

Fetched today. bulkglp.com is a WooCommerce storefront whose own footer research-use notice states "BulkGLP is a wholesale chemical supplier" and separately disclaims 503A/503B pharmacy status. The WooCommerce Store API (wp-json/wc/store/v1/products) lists 48 items total; 8 of those are $0.00 packaging or mailer add-ons rather than compounds (five vial-box options, counting the two separate 1-vial boxes for the 10ml-vial and 3ml-peptide formats plus the 3, 5 and 10-vial boxes, and three envelope options, USPS Express Padded, USPS Priority Padded and FedEx Pak), leaving 40 priced products; the full 48-item payload was re-pulled and re-counted 2026-08-26. Retatrutide is carried under two separate product lines rather than one: a finished-vial line, "Retatrutide (LY3437943) Research Peptide" (product id 1035, slug retatrutide-ly3437943-glp1r-glp3), and a raw powder line, "Retatrutide (LY3437943) Lyophilized Research Powder" (product id 4245, slug retatrutide-powder), which carries an additional "Bulk Raw Research Powders" category alongside the same "Retatrutide Reference Materials" category the vial line uses, so the two lines share a category rather than sitting in wholly separate ones (category lists re-read from both product records 2026-08-26). The vial line's Size attribute lists 5mg, 10mg, 12mg, 15mg, 20mg, 30mg and 50mg plus five "X - 10 Pack" kit options (5mg, 10mg, 15mg, 20mg and 30mg), but among the singles only 10mg, 12mg, 15mg, 20mg, 30mg and 50mg (Standard formulation) resolve to a purchasable variation, and among the packs only the 10mg, 15mg, 20mg and 30mg kits do; the 5mg single and the 5mg 10-pack alike have no matching SKU behind them (attribute terms and variations re-read from the live product record 2026-08-26). A second attribute, Formulation, offers Standard and Mannitol Free; Mannitol Free is purchasable at 10mg and 15mg but the 20mg and 30mg Mannitol Free variations, while listed, read out of stock. The powder line's Size attribute lists 100mg, 250mg, 500mg, 750mg and 1g, but only 500mg and 1g resolve to a purchasable variation. On documentation, this is one of the more thorough sites in this project: a dedicated /verified-quality/ archive lists 36 current and 13 prior batch reports across 29 products, 49 reports in total, each naming a lot, a report ID, the measured content and purity, and linking a self-hosted PDF or PNG. The retatrutide vial line alone carries 6 current and 10 prior reports. The current 10mg report (lot 062503, report ID 2606190261, dated Jun 23, 2026) states net content 11.20 mg and purity 99.87 percent by the method named on the document face; I downloaded that PDF directly (310,299 bytes) and its text layer matches the on-page badge exactly. The product page's own "Lot-Specific Analytical Records" panel and the separate /verified-quality/ archive agree with each other for every figure I cross-checked.
On the laboratory named on the retatrutide certificates, Freedom Diagnostics. The PDF I opened for the current 10mg lot names the issuer as FreedomDiagnosticsTesting.com, gives a client field of BulkGLP, an accession number of 2606190261, and a search code of Bulk2606190261, following the same "first four letters of the client name plus the accession number" convention documented for this lab elsewhere in this project. The method lines on the document read HPLC with UV detection coupled with mass spectrometry for identity, HPLC-UV for purity, USP <85> Limulus Amebocyte Lysate for endotoxin, and PCR for microbial screening. I exercised the lab's own verification route rather than only reading the vendor's copy: requesting https://coas.freedomdiagnosticstesting.com/Bulk2606190261.pdf returned HTTP 200 and a file that is byte-for-byte identical (matching MD5 checksum, both 310,299 bytes) to the PDF bulkglp.com hosts itself, while a control code one digit off, Bulk9999999999.pdf, returned HTTP 404. This is the same laboratory documented against Full Scale Peptides earlier in this project, on the same domain, using the identical search-code convention; one certificate I opened for a different BulkGLP product (ARA-290, detailed in the cautions below) is signed by Alex Johnson, Principal Chemist, the same signatory name recorded on Full Scale Peptides' later-generation certificates from this lab. Freedom Diagnostics makes no testing-competence accreditation claim that I found on bulkglp.com's own pages; I did not re-fetch the lab's homepage on this pass since it was already documented earlier in this project.
Benchmark and prices read from the WooCommerce Store API and the product page on 2026-08-26. Retatrutide, Standard formulation, single vial: 10mg $120.00, 12mg $133.00, 15mg $149.00, 20mg $189.00, 30mg $228.00, 50mg $346.00. The same sizes also sell as 10-vial kits: 10mg-pack $949.00, 15mg-pack $1,193.00, 20mg-pack $1,369.00, 30mg-pack $1,799.00, working out to roughly 21 to 28 percent per vial below the equivalent number of singles. A Mannitol Free formulation costs more at matching sizes: 10mg $153.00 and 15mg $193.00 are in stock; 20mg $232.00 and 30mg $281.00 are listed but out of stock. The separate raw-powder line prices at $1,780.00 for 500mg and $3,483.00 for 1g, both in stock. Elsewhere in the 40-item priced catalog: Thymalin 10mg $68.00, FOXO4 10mg $177.00, PT-141 10mg $68.00, Epitalon 50mg $183.00, AICAR 50mg $72.00, ARA-290 (single strength) $80.00, SS-31 1000mg $2,863.00, GHK-Cu 10,000mg $1,395.00, Thymosin (TA-1) 1000mg $5,250.00, Selank 1000mg $2,100.00, Semax 1000mg $2,100.00, VIP 1000mg $2,263.00, a semaglutide line (GLP1S) at 20mg $99.00 and 1000mg $1,699.00, and a tirzepatide line (GLP2-T) at 40mg $140.00 and 1000mg $2,599.00; several of the higher-gram listings read as bulk reference-material pricing rather than single-patient retail vials, consistent with the site's own "wholesale chemical supplier" self-description. Shipping, per /shipping-policy/ (dateline October 2, 2025), processes orders in 1 to 2 business days via USPS, UPS or FedEx with rates calculated at checkout rather than posted as a flat table; domestic transit runs 3 to 5 business days Standard, 2 to 3 Expedited, 1 day Overnight where supported, and the same page states the site also ships to "select countries" internationally, with duties, taxes and customs risk placed on the recipient, a wider ship-to footprint than several US-only peers in this project. The refund policy (dateline March 25, 2026) gives a 30-day window for eligible issues, excludes opened, punctured or reconstituted vials, and explicitly addresses the chargeback path, stating the vendor may supply order records and tracking to a payment processor if one is filed. The Terms and Conditions set the purchaser age floor at 21 (section 3) and governing law to the State of Texas (section 16), consistent with the Dallas street address given for the entity. Entity and contact: "BulkGLP" at 1910 Pacific Ave, Ste 2000 #1534, Dallas, TX 75201, phone 972-767-9536 (matching the tel: link in the page footer), email support@bulkglp.com; no LLC, Inc or other legal-entity suffix appears anywhere I loaded, only the bare trade name "BulkGLP." Payment methods are not named on any policy page, the product page, or the cart page I loaded; I did not reach an actual checkout step to see what is offered there.
CAUTIONCautions noted. First, the same lot number carries two materially different Freedom Diagnostics readings for the retatrutide 10mg vial: the archive's "prior" report for lot 062503 (report ID 2605280328, dated May 30, 2026) states net content 12.05 mg and purity 99.76 percent, while the "current" report for the identical lot number (report ID 2606190261, dated Jun 23, 2026) states net content 11.20 mg and purity 99.87 percent, a roughly 8 percent swing in measured content under one lot identifier three weeks apart. Neither the product page nor the /verified-quality/ archive explains why one lot carries two differently dated, differently valued reports; the site's own About page states plainly that "the report for the listed lot is the controlling record," which does not resolve which of the two controls when both claim the same lot. Second, and more serious: I opened the vendor's own published Freedom Diagnostics certificate for ARA-290 10mg (accession 2604170157, lot 90133, dated 04/19/2026) and its Sample Summary states Purity 53.90 percent by HPLC-UV against an Identity line marked Confirmed, with a chromatogram showing a large co-eluting peak labelled Methionine ahead of the ARA-290 peak. That is the only current report published for ARA-290 anywhere on the site, and the product remains listed in stock at $80.00 with no flag, discount or caveat on its own product page pointing a buyer toward that reading; the page's meta description asks a visitor to "review the active lot report" for purity rather than stating a number itself, which is technically accurate but places the entire burden of catching a sub-54-percent reading on a buyer who follows through and opens the linked document. The site's Organization-level structured data still describes BulkGLP generally as a supplier of "high-purity research peptides," a blanket claim this one archived report does not support. Third, both retatrutide lines advertise size options with no purchasable SKU behind them: the vial line lists a 5mg single and a 5mg 10-pack, and the raw-powder line lists 100mg, 250mg and 750mg sizes, none of which resolve to an actual variation in the store's own product data. Fourth, the site's structured data types BulkGLP's Organization entry as both "HealthAndBeautyBusiness" and "Organization," an odd schema category for a business that elsewhere describes itself as a wholesale chemical supplier serving laboratories; this is a metadata choice rather than a claim made to a visitor, but it is the kind of detail a shopping feed or search engine reads literally. Fifth, payment methods are undisclosed anywhere short of an actual checkout, which I did not attempt; every other policy surface on the site (shipping, refunds, age eligibility, governing law) is specific and dated, which makes the total silence on payment options a more visible gap than it would be on a thinner site.
