At a glance
- Official shop is aavantpeptides.com. Extra domains copy the name.
- Finnrick: 19 of 19 passes, but only tirzepatide and retatrutide.
- One public row: retatrutide 99.9% HPLC, fill +12%, 11 Feb 2026.
- Finnrick could not resolve a named US company. Crypto checkout.
- Use Ascension when you want a lot library we already host.
Finnrick's board on this shop is clean. Nineteen tests, nineteen passes, #5 of 301 vendors as of 4 August 2026. That is a real independent trail. It is also only two peptides: tirzepatide and retatrutide.
The rest of the story is thinner. Finnrick's 3 July 2026 vendor-intelligence note says corporate and domain records do not resolve a named US counterparty, and the working storefront has shifted to irreversible crypto rails. There is also an Aavant-branded clone neighborhood.
This review is aavantpeptides.com. It is not aavantpeptidesofficial.com. Finnrick also lists aavant.net as a second host. Type the URL yourself.
Bottom line: Independent sampling on two GLP-class SKUs is strong (19/19 pass). The company behind the site is not. Fine as a one-off if you match a printed lot to a Finnrick or vendor sheet on tirzepatide or retatrutide. For a catalog we already index lot by lot, start at the Ascension Peptides review. Code ENHANCED is 50% off.
What we can actually name
The live shop is aavantpeptides.com. Support on the FAQ footer is aavant@peptide.email. Finnrick labels the vendor Aavant Research and lists location as US. We did not independently pull a secretary-of-state filing with a matching legal name in this pass. Treat "US" as a Finnrick tag, not a verified officer list.
The catalog, from the public storefront and Finnrick's rated set, is built around GLP-class vials. Community writeups also mention the usual research list (BPC-157, TB-500, secretagogues). We are not repeating a full SKU table we could not load through Cloudflare. Confirm the product page, then confirm the lot.
RUO copy is standard: research use only, not for human consumption.
Finnrick is the evidence. It is also the limit.
Finnrick's Aavant Research page (read 17 August 2026): 19 tests, 2 peptides, 19 pass / 0 fail, 87% rating, #5 of 301.
| Peptide | Tests | Finnrick rating | Notes |
|---|---|---|---|
| Tirzepatide | 12 | 89% | Latest row 4 August 2026 |
| Retatrutide | 7 | 85% | One public COA snippet: 11 Feb 2026, 99.9% HPLC, fill +12%, identity pass |
Finnrick's own summary: identity and purity look consistent; fill is more dispersed, especially high tirzepatide fills and wider retatrutide variance. That is the honest read of a 19-row board. It does not grade BPC-157, the stacks, or anything else in the shop.
One public retatrutide certificate we could see without a login: 11 February 2026, 99.9% HPLC, fill +12%, identity pass. Fill +12% is not a fail under Finnrick's ±35% purity-focus rule. It is still a labeling problem if you run the retatrutide dosage chart or the reconstitution calculator off the printed milligrams.
Illegal peptide vials seized in Europe have shown purity as low as 5% to 75% on cysteine sequences, plus arsenic and lead above parenteral limits (Janvier et al., 2018). Custom peptides have arrived with undeclared mannitol at 20% and 43% by weight (Choules et al., 2020). Online semaglutide bought without a prescription has measured 7.7% to 14.4% purity against a 99% label (Ashraf et al., 2024).
The method, without a vendor attached, is what a peptide COA actually is. Worked examples live in the lab-tests library.
The company, the crypto rail, and the extra domains
Finnrick's paid intelligence report (dated 3 July 2026; the public blurb is what we cite) lists three risks we will not dress up:
- No named US counterparty in the corporate and domain records they checked.
- Checkout has moved onto irreversible crypto rails.
- Unauthenticated Aavant-branded storefronts, "Andy Peps Studio" signals, and Telegram impersonation paths.
We did not buy that PDF. We are repeating the public summary, not inventing officers or wallet addresses. If you need a named company, a card checkout, and a lot you can open before you pay, this is not that shop.

Aavant is not a one-week ghost. The Finnrick board on tirzepatide and retatrutide is one of the cleaner two-SKU trails in that dataset. The reason we still point a multi-compound plan at Ascension is a named storefront, a public lot library we host, and a checkout that is not a wallet.
Buy here if the URL is aavantpeptides.com, you are looking at a SKU Finnrick has actually sampled, and you will match the printed lot to a dated sheet. Cross-check lots at lab-tests/tirzepatide and lab-tests/retatrutide.
Walk if you need BPC-157 history, if an ad sent you to aavantpeptidesofficial.com, or if you will not pay in crypto and cannot confirm a named company.
If you want paperwork we already host before checkout, the Ascension Peptides review and the best legit peptide vendors list are the next two clicks. Code ENHANCED is 50% off injectables.
