NextSelf Labs
COA coverageShare of the products this vendor sells that have at least one COA opening at the testing lab. Extra documents for the same product do not change it. Pages that refuse our reader are marked partial and never lower anything. It describes what a vendor publishes, not purity. How we count
We show no percentage here: the gap is in our reading, not in what the vendor publishes. It lowers nothing.
Independent price profile. We track 42 tracked peptide listings from nextselflabs.com · online since Apr 2026How 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: $0.04/mg.
Evidence note: 2026-11-14: /certificates-of-analysis/ indexes every product (37) with structured per-report data (lot, COA #, lab, purity, date): ILS Laboratories and Freedom Diagnostics reports, PDFs hosted on nextselflabs.com. New since 11-06: the page now links 28 distinct ILS verify pages (portal.ils-lab.com/verify/<id>; about 31 of 37 products). ILS is not in the lab registry (src/lib/coa-detect.ts KNOWN_LABS), so those links are not credited as lab-hosted today. ILS Laboratories is named here as the vendor's own attribution only: it is not in KNOWN_LABS and the 2026-11-14 lab audit rated it UNCLEAR, so it is not listed in labPartners (same treatment as Accurate Test Labs and Accumark). Publication observed, not a purity certification.
Vendor-published info captured from NextSelf Labs's own site — not tested or verified by pepmg. Confirm on their site.
Domain age from public registration records (RDAP) + the Wayback Machine — the domain's age, not proof of how long the business has operated.

Compared with every in-stock, single-compound listing pepmg tracks for each compound (bulk packs, blends and out-of-stock items left out). The axis is the ratio to that compound's median, so every row shares it.

NextSelf Labs scores 76/100 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: third-party COAs, self-hosted. The biggest credibility signal pepmg weighs is how a vendor publishes lab tests: it names a third-party lab (Freedom Diagnostics) but hosts the documents on its own site, so pepmg can see the claim but not confirm it at the lab. Neither price nor catalog size affects this score, but for context it prices around the tracked median across the compounds it shares with other tracked vendors, over 32 tracked listings. Its prices are machine-readable and it publishes a brief About page, and the domain is newer, online since Apr 2026, which pepmg counts as neutral rather than a mark against it. This rates what NextSelf Labs 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.
- Strength Third-party lab named (Freedom Diagnostics) — documents self-hosted, not lab-confirmable
How we scored this
| COA transparency | | 67/87 | third-party lab named (Freedom Diagnostics) — documents self-hosted, not lab-confirmable |
| About / who they are | | 4/8 | brief About page |
| 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 | 1.00x the tracked median across 24 shared compound(s) |
| Catalog | 32 clean in-stock listing(s) tracked |
| Track record | active · new domain (online Apr 2026) — no age penalty |
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.
- Results hosted on the testing lab's own site, where the lab itself can confirm them, read stronger than documents hosted on the vendor's own site. (up to +20)
- An About or founder page saying who is behind the business. (up to +4)
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.

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 NextSelf Labs, 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.
