Zenergy USA Review: Pricing, COAs, Testing, and What We Found
An independent Zenergy USA review covering Albany, GA contact details, openly priced research vials, ZEN house labels for GLP compounds, and provider-verified Kovera, Chromate, and Freedom certificate images.
Zenergy USA is now a curated vendor on PeptideBenchmark. That decision rests on what a reader can check without guessing — public prices, milligram strengths, house-label mappings, a street-level contact address, and third-party certificate images that can be re-checked at the issuing laboratories.
Reviewed August 8, 2026. PeptideBenchmark has no affiliate, coupon, sponsorship, or paid-placement relationship with Zenergy USA. The vendor sells research-use-only products; this is a commercial-transparency and documentary-evidence review, not human-use guidance or medical advice.
The short version
We found a research storefront with:
- openly priced single-vial offers and size variations on the public catalog;
- a published Albany, Georgia contact address;
- house labels ZEN 1 SM, ZEN 2 TZ, and ZEN 3 RT for semaglutide, tirzepatide, and retatrutide;
- a Certificates library whose HTML table requires login, while the linked COA PNGs remain publicly downloadable and largely provider-verifiable.
The catalog is usable for $/mg comparison without an account. After authorized enumeration of the Certificates index, PeptideBenchmark confirmed 79 of 83 current origins at Kovera Labs, Chromate, or Freedom Diagnostics under Zenergy client identities. Browsing the HTML table still needs an account; the image files and laboratory lookups do not.
What we found in the catalog
Zenergy USA exposes live list and sale prices through its public catalog. Most research peptides expand cleanly into milligram rows. PeptideBenchmark promotes every clean mg-normalized vial so Pricing and Stack Builder stay honest.
| Catalog result | Count | PB treatment |
|---|---|---|
| Public parent products | 60 | Retained in the coverage audit |
| Comparable vial rows after size expansion | 72 | Published to Pricing and Stack Builder |
| Deferred | 2 | IGNITE and PEACEFUL FOCUS branded blends |
| Out of scope | 10 | Cosmetics, reconstitution water, Lipo-C, B12 |
House labels matter here:
- ZEN 1 SM → semaglutide
- ZEN 2 TZ → tirzepatide
- ZEN 3 RT → retatrutide
- ZEN 1 SM / CAGRI → cagrilintide / semaglutide blend
Current offers can be compared on PeptideBenchmark Pricing, and mixed-product requirements can be modeled in the Stack Builder.
Testing transparency
The nav label Certificates points at /test-results/. An anonymous visit lands on a login wall, so the table itself is not a public archive browser. Each View COA cell, however, links a PNG under /wp-content/uploads/coas/ that downloads without credentials.
In the August 8, 2026 authenticated enumeration, PeptideBenchmark reviewed 83 peptide-board certificate origins (support documents such as bacteriostatic water were excluded):
| Laboratory | Origins | Provider-verified |
|---|---|---|
| Kovera Labs | 65 | 65 |
| Chromate | 12 | 9 |
| Freedom Diagnostics | 6 | 5 |
Average reported purity across extracted reports was about 99.7%. The Kovera set commonly includes identity, HPLC purity, net content, endotoxin, sterility, and heavy-metals screening. Three Chromate images remain vendor-hosted only because OCR did not recover a usable job/access pair in this pass.
A matched certificate documents the tested sample. It does not endorse every vial on the shelf, every unlisted panel, or any use outside research.
What this does not prove
A priced catalog, a street address, and provider-verified certificates do not prove:
- chain of custody from a tested sample to current inventory;
- that every in-stock SKU has a current certificate;
- that three older Chromate images without recoverable credentials are invalid — only that PB could not independently look them up in this pass;
- or safety, sterility, or suitability for any use beyond what the named report panels actually state.

Common questions
Is Zenergy USA legitimate?
PeptideBenchmark does not issue binary legitimacy or product-safety endorsements. We confirmed an openly priced research catalog, a public Albany, Georgia contact address, and a large set of third-party certificate images that resolve at Kovera Labs, Chromate, and Freedom Diagnostics under Zenergy client names. Those facts create an inspectable commercial and documentary record; they do not establish the condition or safety of a physical vial.
Does Zenergy USA publish COAs?
Yes, with a nuance: the Certificates HTML page at /test-results/ requires login, but each View COA link is a publicly downloadable PNG under /wp-content/uploads/coas/. PeptideBenchmark enumerates that library with an authorized account and verifies the public images at the issuing laboratories.
What do ZEN 1 SM, ZEN 2 TZ, and ZEN 3 RT mean?
They are Zenergy USA storefront labels. PeptideBenchmark maps ZEN 1 SM to semaglutide, ZEN 2 TZ to tirzepatide, and ZEN 3 RT to retatrutide for cross-vendor comparison.
Where is Zenergy USA based?
Public contact and footer pages list Zenergy at 2800 Old Dawson Road Suite 2 #103, Albany, GA 31707, with support@zenergyusa.com.
Does PeptideBenchmark have an affiliate relationship with Zenergy USA?
No. At the time of this review, PeptideBenchmark had no affiliate, coupon, sponsorship, or paid-placement relationship with Zenergy USA.
