Testing and COA Transparency
Both vendors present meaningful testing or documentation signals, but they do it differently.
Ultima Labs has improved significantly due to a growing public Janoshik library. This gives users more visible testing records to review, including report details, sample names and purity-style data where available.
Zenith Supply Group has a dedicated Certificate of Authenticity section and states that every compound is backed by batch-specific documentation. Its review also notes that COA images are uploaded for products and updated as new batches arrive.
Stronger where users value public Janoshik-style report visibility and a growing testing library.
Stronger where users value a dedicated COA section and batch-specific documentation across product listings.
Payment Methods and Checkout
Both vendors are stronger than bank-transfer-only suppliers because they offer more conventional payment pathways.
Zenith Supply Group lists credit card, direct bank transfer, Google Pay and pay via invoice. That is a strong mix because it gives users several checkout options without forcing everyone into one manual payment method.
Ultima Labs also presents a more polished ecommerce checkout than many smaller suppliers, with credit/debit cards, selected digital payment options and approved alternative payment methods noted in its broader vendor review.
Clearer payment method list and strong flexibility with card, bank transfer, Google Pay and invoice.

Product Range and Catalogue Depth
Ultima Labs has the edge for catalogue depth. The vendor lists a broad range of research compounds, starter kits, bacteriostatic water and bundle-style products. Its catalogue includes common research compounds across GLP, recovery, cognitive, longevity and general peptide categories.
Zenith Supply Group also carries a strong range, including individual compounds, blends, diluents and research materials. The Zenith review notes products such as Retatrutide, BPC-157, BPC-157/TB-500 blend, CJC-1295, Ipamorelin, GHK-Cu, Tesamorelin, Melanotan II, MOTS-C, Kisspeptin, SS-31, NAD+, Epithalon and Pinealon.
The difference is that Ultima appears more catalogue-heavy and ecommerce-oriented, while Zenith appears more focused and value-driven.
Broader catalogue, starter kits and bundle options.

Zenith Supply Group also has a clean product layout, visible pricing, dedicated COA page, FAQ section, contact page, standard cart/account functionality and clear support information. Its website repeatedly communicates same-day dispatch, express shipping and discreet packaging.
If judging only by ecommerce polish and catalogue presentation, Ultima Labs has the slight edge. If judging by directness, clarity and purchase simplicity, Zenith is very competitive.
