Where 24-to-4 comes from: five compounds worth pricing line by line
The table is the reference view, trimmed to 10 of the 28 comparable rows. Each line uses the cheapest in-stock package per compound, normalized to its standard research amount. Both codes are 10%, and the same vendor is lower on every row after them.
| Compound | Puratek Peptides packages | Glacier Aminos packages | Puratek Peptides per std | Glacier Aminos per std | Lower before code |

GLP-3R: an 8% gap across five Glacier sizes
Puratek sells three sizes: $44.95 at 10mg, $64.95 at 20mg and $89.95 at 30mg. Glacier's five run $51.29 at 10mg, $89.09 at 20mg, $129.59 at 30mg, $213.99 at 50mg and $196.19 at 60mg. Normalized, Puratek is $29.98 against $32.70 per 10mg, or $26.99 against $29.43 after codes, 8% less. Puratek's ILS 10mg report measured 10.65 mg. Glacier's Ethos 20mg report shows 20.81/20.69 mg at >99% purity, and the 20mg and 60mg rows carry exact current Kovera records. The 10mg, 30mg and 50mg rows get no badge, and the 60mg package costs less than the 50mg.
GLP-2T: a 41% gap that survives both codes
Puratek's three sizes are $39.95 at 15mg, $59.95 at 30mg and $89.95 at 60mg. Glacier's five are $45.89 at 10mg, $68.39 at 20mg, $88.19 at 30mg, $131.99 at 45mg and $152.09 at 60mg. Normalized, Puratek is $14.99 against $25.35 per 10mg, or $13.49 against $22.81 after codes, 41% less. Puratek's ILS 30mg report measures 32.17 mg across three vials. Glacier's exact controls require compound, strength, unit and formulation to match, so the badge has to line up with the vial you buy.
BPC-157: $29.95 against $41.39, with an exact report on the 10mg
Puratek charges $29.95 for 10mg. Glacier charges $41.39 for 10mg and $71.99 for 20mg, which normalizes to $36.00 per 10mg. After codes the figures are $26.96 and $32.40, a 17% Puratek advantage. The BPC-157 record is specific: lot BPC10005 measured 99.96% and 99.84% purity at 10.70 mg and 10.45 mg, with ILS testing two or three vials per report. Glacier's 20mg row has an exact current Kovera record; its 10mg row gets no badge.
MOTS-c: the widest gap in the table
MOTS-c shows the widest split in the shared table. Puratek's 10mg is $29.95 and its 40mg is $69.95; Glacier's 10mg is $41.39 and its 20mg is $71.99. Normalized, Puratek is $17.49 against $36.00 per 10mg, or $15.74 against $32.40 after codes, 51% less. Puratek's ILS coverage lists MOTS-c 10mg with measured content above its label. On Glacier, match the badge to the exact strength and unit.
Tesamorelin: a 7% gap and a metals note
Puratek's 10mg is $54.95 and its 20mg is $104.95; Glacier's are $61.19 and $112.49. Normalized, that is $52.48 against $56.24 per 10mg, or $47.23 against $50.62 after codes, 7% in Puratek's favor. The Tesamorelin paperwork matters more than the price. Puratek's 10mg report has matching V0, V1 and mean purity and content, with only the printed endotoxin method differing. Its 20mg report differs in quantified metals below the printed limits, one of the six source-version sets that receive no exact listing control.
The rest of the price picture, including Glacier's four wins
Both vendors stock 29 of the same compounds. Twenty-eight are directly comparable; TB-500 is the exception because Puratek lists its size as n/l at $59.95, so no normalized figure exists. Puratek is lower on 24 of the 28 and Glacier on 4, with the same split after both codes.
Glacier's four wins are 5-Amino-1MQ at 49% less ($18.00 against $34.95 per 10mg), Kisspeptin-10 at 8% less ($36.89 against $39.95), GLP-1S at 7% less ($32.39 against $34.95) and Thymosin Alpha-1 at 4% less ($57.59 against $59.95). The 5-Amino-1MQ number depends on Glacier's $89.99 50mg package; its 10mg vial alone is $46.79, above Puratek's $34.95.
Puratek's widest gaps are MOTS-c at 51%, GLP-2T at 41%, NAD+ at 40%, SS-31 at 40% and DSIP at 35%. Package size can flip the sticker: Glacier's 50mg GHK-Cu at $27.89 undercuts Puratek's $28.95, yet the normalized figures are $3.50 against $4.14 per 10mg because Puratek's 100mg vial is $34.95 against $41.39. One standard amount of every comparable compound totals $887.91 at Puratek and $1048.96 at Glacier before codes, and $799.12 against $944.06 after them.
At the edges, IGF-1 LR3 is the only compound stocked by Puratek alone. Glacier alone stocks 13, including AHK-Cu, CJC-1295 (With DAC), Cartalax, FOXO4-DRI, Oxytocin, Pinealon, SLU-PP-332, Sermorelin, Tesofensine, Testagen, VIP and Wolverine.
58 reports against 288: what each certificate library proves
Puratek's public archive holds 58 report sets across 110 pages, 51 from ILS Laboratories and seven from Freedom Diagnostics. Fifty-two have exact issuer matches naming Puratek; six retain source-version differences between merchant files and live issuer records. The archive was checked on October 4, 2026, and the newest matched analysis is dated August 5, 2026. Fourteen of the 16 newly linked sets include fentanyl screening, and extended reports add ICP-MS metals, microbial PCR and endotoxin. Thirty-five of 39 in-stock listings carry an exact issuer-verified certificate. The COA library keeps the originals.
One report is the exception. Epitalon 10mg lot EPI10003, report COA-2026-NPZJOE, prints endotoxin 0.157 EU/mL PASS in the merchant file, while the live ILS record prints 2.87 EU/mL FAIL against a 0.5 EU/mL limit. Both versions remain available, and the affected report receives no exact listing control, as do the six unresolved sets. The owner approved the 9.5/10 COA factor on October 4, 2026 and retained the 10/10 overall score.
Glacier's archive is larger: 288 records across 415 certificate pages, 282 issuer-verified. Six Forever Young Pharmacy records were checked but have no public issuer lookup. All 32 current Ethos reports completed company and sample lookups and returned exact original PDFs; 13 are new and 19 preserve earlier identities. Two Kovera sets include every official panel, and three older Vanguard capsule records match specific laboratory records. Three Freedom no-match records and one Vanguard registry/PDF report-ID conflict remain internal quality holds. The newest matched analysis is dated September 9, 2026, and 53 of 57 in-stock listings carry an exact issuer-verified certificate. Current shipped lots remain unconfirmed.
Puratek names two labs on matched listings, ILS Laboratories and Freedom Diagnostics. Glacier names four: Kovera Labs (33), Ethos Analytics (17), Freedom Diagnostics (2) and ILS Laboratories (1), with Vanguard and Forever Young Pharmacy in the wider archive. The COA factors are 9.5 and 8. Reputation ties at 9. Transparency is 10 against 8, and Puratek publishes its entity name, a Las Vegas suite address, a telephone number and a support email alongside its shipping, refund and purity policies.
Both reader codes take 10%, so the ranking does not move
Both vendors have a working reader code, and both take 10% off. Puratek's is PEPTIDEPRICES, verified by PeptidePrices and checked on October 3, 2026. Enter it separately at checkout; it does not apply automatically, and the 10% reduction was confirmed on September 8, 2026. Terms are on the Puratek coupon page.
Glacier's is peptidep, also 10%, also verified and checked on October 3, 2026, with the checkout reduction confirmed on September 8, 2026. Terms are on the Glacier coupon page.
Equal percentages mean the code step changes the totals but not the winner on any row. One standard amount of every comparable compound falls from $887.91 to $799.12 at Puratek and from $1048.96 to $944.06 at Glacier. Confirm the code at checkout before paying.
US-only dispatch on one side, unverified checkout fields on the other
Puratek ships to the United States only, including USPS service to P.O. boxes. Standard shipping is free over $150, and orders placed before 1 PM Pacific on a business day ship the same day. Payment is Zelle, Cash App or Venmo. All sales are final, replacements cover only verified shipping damage or fulfillment errors, and the 98.5% purity guarantee allows a 30-day claim on unopened vials retested by a named laboratory. Because payment is transfer-only, there is no card chargeback path. Browsing requires an account and a confirmation that the buyer is at least 21 and purchasing for research use.
Glacier's ships-to and payment fields are not verified in the PeptidePrices record. It publishes 24 to 48 hours of handling, $14 standard delivery within three business days, $49 overnight, and five to seven days for Puerto Rico or the US Virgin Islands. Sales are final after shipment. The guarantees are a 99%+ purity replacement and 50% store credit for independent retesting. Vendor metadata lists card acceptance, but the payment field stays unverified. The public contact address is in Fort Collins, Colorado, a contact location rather than proof of a manufacturing site. Use glacieraminos.shop; glacieraminos.com is an impersonator risk.
Who should pick Puratek, and who should pick Glacier
Pick Puratek if the score and per-record certificate detail matter most, if your list is GLP-2T, MOTS-c, BPC-157, NAD+, SS-31 or ARA-290, and if US-only delivery plus Zelle, Cash App or Venmo works for you. Free shipping starts at $150, and orders before 1 PM Pacific ship the same day. The trade-offs are an account wall, a 21-or-older research-use confirmation and final sales.
Pick Glacier if you need breadth: 42 in-stock compounds against 30, including 13 that Puratek does not stock. It is also the fit for overnight delivery, Puerto Rico or the US Virgin Islands, the 50% store credit for independent retesting, or a vendor with an independent review record. The 4.6/5 from 117 Trustpilot reviews is the only review aggregate either vendor has on file.
Neither profile is a clean sweep. A buyer sourcing GLP-1S, Kisspeptin-10, Thymosin Alpha-1 or a 50mg 5-Amino-1MQ package saves at Glacier; a buyer sourcing most of the rest of the shared catalog saves at Puratek. Match the certificate to the exact product, strength and lot before relying on it. Full evidence: Puratek Peptides review and Glacier Aminos review.
