Zenith Bioscience
Independent price profile. We track 37 tracked peptide listings from zenithbioscience.com · online since 2013How long the vendor's website domain has existed — from public registration records and the Wayback Machine. It's the domain's age, not proof of how long the business has run. · cheapest tracked: $0.60/mg.
Evidence note: Organization schema + /legal/authenticity claim "third-party analytical testing for purity and identity" and a COA per batch, but verification happens through Zenith's OWN online batch-number lookup — no named third-party lab (no Janoshik/other lab brand) appears anywhere on-site. Existence of a COA program only, not a purity/authenticity claim. Verifiability tier left to the daily coa-scan. Products labeled research use only.
Domain age from public registration records (RDAP) + the Wayback Machine — the domain's age, not proof of how long the business has operated.

Zenith Bioscience scores 5/100 in pepmg's criteria-based Vendor Score, which rates only what a vendor publishes about lab testing and about itself, not its products and not its prices. What we observed: no lab testing published that we could find. The biggest credibility signal pepmg weighs is how a vendor publishes lab tests, and pepmg found none published where it could read them. Neither price nor catalog size affects this score, but for context it prices below the tracked median across the compounds it shares with other tracked vendors, over 24 tracked listings. Its prices are machine-readable, and the domain has been online about 13.1 years. This rates what Zenith Bioscience publishes about lab testing and about itself, not the purity or authenticity of any vial, which pepmg can't verify, so read the COAs yourself. Research use only.
- Room to improve pepmg found no publicly readable third-party COA program
How we scored this
| COA transparency | | 0/87 | third-party lab program UNVERIFIED — vendor can verify |
| About / who they are | | 0/8 | no About/founder page found |
| Public price data | | 5/5 | publishes machine-readable public prices |
Stated, but NOT scored. These describe the vendor; they earn no points either way.
| Price vs market | 0.65x the tracked median across 24 shared compound(s) |
| Catalog | 24 clean in-stock listing(s) tracked |
| Track record | established — domain online ~13.1y (since 2013) |
What would raise this score. Published behaviour only. How a vendor runs its business is its own call, and none of this affects the $/mg ranking.
- A publicly reachable certificate, meaning a PDF anyone can open without an account, is the single biggest factor here. (up to +30)
- An About or founder page saying who is behind the business. (up to +8)
Computed from what this vendor publishes about lab testing and itself. Price and catalog size are shown above as facts and are deliberately NOT scored — $/mg is the ranking, and it is affiliate-blind. No opinions, no testimonials.

COA library (0 indexed records)
Browse every document and report currently indexed for this vendor. A COA covers its stated product and batch; a vendor-level link does not establish a match to every listing. Some labs limit automated access.
No individual documents are indexed yet. A public COA library link is not recorded.
We don't host reviews — an unverifiable review box is a magnet for bots and paid posts, and we won't pretend otherwise. Instead, here's where you can read what real buyers say about Zenith Bioscience, on sites we don't control:
These are independent, unmoderated sources — we link them, we don't vouch for them, and a "profile" or "search" link may turn up little or nothing. pepmg's job is the part we can stand behind: prices captured first-party with a timestamp, ranked purely by $/mg, plus the objective Vendor Score above. Vetting a source you're about to buy from still matters, and that call is ultimately yours — we've made it as informed as we honestly can.
