“Established US-domestic peptide synthesizer with a substantial catalog and same-day shipping. COA practices are the open question — testing is claimed in marketing copy but not surfaced on product pages or a public lab-results route. Public-data preview; first-hand audit pending.”
pros
+US-based synthesis and lyophilization (claims peptides are produced and freeze-dried in-house in the United States)
+Substantial catalog — 88 SKUs spanning healing, growth, longevity, and metabolic peptides (no GLP-1s)
+Same-day shipping if orders are placed by 1pm PST
+Free replacement on damaged or lost packages
+Explicit 503A non-compliance disclaimer (research-grade only — honest framing)
+Affiliate program available
cons
−COAs are claimed in About-page marketing copy ("HPLC, Mass Spectrometry, and Certificate of Analysis evaluations") but do not appear on product pages, a /coa route, or any other public surface we could find
−In-house testing rather than third-party labs (per their about-page description) — different evidence class than vendors who publish Janoshik or MZ Biolabs reports
−No GLP-1s (Retatrutide / Tirzepatide / Semaglutide) — so cross-vendor comparison on the headline GLP-1 cluster is not possible against this vendor
−No returns policy (typical for the niche — flagged for transparency)
−This profile is preview-data only; first-hand audit pending

Audit notes
What we read
For this preview profile we synthesized the vendor's public catalog
(88 products fetched at the time of audit, 13 tracked-compound matches),
their about-page and shipping-policy disclosures, and the structure of
their product pages — specifically looking for whether a Certificate of
Analysis is published per-batch or aggregated on a public route. We did
not place a test order.
Why BioTech Peptides matters in 2026
BioTech Peptides is a long-running US-based research-peptide vendor with a
catalog that spans most of the non-GLP-1 mainstream — BPC-157, TB-500,
GHK-Cu, MOTS-c, Tesamorelin, NAD+, AOD-9604, plus a wider set of blends
and less-common compounds. Their about-page positions them as in-house
synthesizers with explicit 503A non-compliance — a more transparent
framing than vendors who blur the regulatory line.
The catalog is one of the deeper research-grade offerings we have indexed
on the price comparison, particularly on the longevity and growth
clusters where most US vendors thin out. NAD+ at 100mg / 250mg / 500mg
sizes is a notable point — only one other vendor we audit lists NAD+ at
all.
What we'd verify in a full audit
The COA gap. Marketing copy claims HPLC, Mass Spectrometry, and
Certificate of Analysis evaluations. We could not find the actual
documents on the site — no per-product COA, no public lab-results page,
no published verification path against an independent lab. A first-hand
audit would either request a batch-specific COA at order time or send
the vial to an independent lab ourselves.
In-house vs third-party testing. The about-page wording suggests
in-house analytical methods. Even if accurate, vendor-internal testing
is a weaker evidence class than COAs from a named third-party lab. We
would want to confirm whether any third-party verification exists.
Shipping reliability. "Same-day shipping if ordered by 1pm PST" is
the stated policy. A first-hand audit would check tracking timelines
against that claim across multiple orders.
Customer-service depth. No public Reddit-thread analysis available
for this vendor at preview time. Worth running before the next audit
cycle.
How BioTech Peptides compares on price
We walk the catalog daily and compare per-mg cost across all six audited
vendors at /peptides-index. Highlights at the time of this preview:
NAD+ at 500mg ($179, $0.36/mg) — cheapest per-mg NAD+ across the
audit set. Only one other vendor (Ascension) lists NAD+ at all, at
$0.12/mg on a 500mg vial.
Tesamorelin 5mg ($38, $7.60/mg) — lowest per-mg tesamorelin in our
index. Swiss Chems' 2mg vial is $13.97/mg.
GHK-Cu 200mg ($186, $0.93/mg) — competitive with Limitless Life
($146.99 at 200mg, $0.73/mg) but cheaper than 50mg tier across all
vendors.
BPC-157 5mg at $52 sits between Particle Peptides ($27.83) and the
upper tier (Pure Rawz $68.27); not market-leading but not premium
either.
Vendor is not listed in Janoshik's current public-test database
under their own brand identifier; absence is consistent with the rest
of our audit cohort and is not by itself a flag (see /articles/janoshik-7164-tests-purity-analysis
for context on why this is structural).
