What It Means to Be a Curated Vendor on PeptideBenchmark
What the "curated vendor" label on PeptideBenchmark actually means: we map the vendor's full catalog into our pricing tools, verify their lab testing against the labs that issued each COA, fold in independent reputation signals, and build a live evidence-based profile. Here is exactly what that involves — and what it does not.
How the Vendor Benchmark Works
The current PeptideBenchmark scoring methodology: source-backed and PB-evidence paths, confidence weighting, testing trust, review signals, pricing coverage, and scoring limits.
From Personal Protocol to Promo Code: Inside the Real Peptides–Michael Morelli Affiliate Funnel

The Peptide Affiliate Disclosure Gap, by the Numbers
We read 15 independent vendor intelligence reports covering peptide vendors we track. Across the ones that published hard counts, only about 1 in 7 affiliate promoters clearly disclosed the relationship — and 14 of 15 reports carry an explicit FTC-disclosure warning. Here is the data, what the FTC actually requires, and where we stand.
When 'Research Use Only' Meets the Owner's Own Posts
A peptide vendor's site says 'research use only — not for human or animal consumption.' Its owner's public posts discuss human weight-loss dosing, two years of human use, and therapeutic 'healing.' We lay the two side by side against the FDA's intended-use standard and let you judge.

On May 21, 2026, Eli Lilly announced TRIUMPH-1 Phase 3 results for retatrutide. The topline showed 28.3% mean weight loss at 80 weeks, plus an unusually large share of participants reaching 30% or greater weight loss.
Eloralintide: Lilly's Amylin Drug Has the Strongest Standalone Phase 2 Weight-Loss Result So Far
Eloralintide is Eli Lilly's once-weekly selective amylin receptor agonist for obesity. Its Phase 2 Lancet data showed up to 20.1% mean weight loss at 48 weeks, putting it at the front of the standalone amylin race.
How to Read a Peptide COA
A peptide COA can be useful, but only if you read it as a batch-specific analytical document instead of a marketing badge.
Petrelintide: Roche and Zealand's Amylin Bet Is About Tolerability, Not Winning the Weight-Loss Arms Race
Petrelintide is Zealand Pharma and Roche's long-acting amylin analog. Its Phase 2 efficacy looked modest next to CagriSema and amycretin, but its placebo-like GI tolerability may be the real strategic story.
What Peptide Testing Can and Cannot Prove
A peptide test report can be useful, but identity, purity, content, sterility, and endotoxin are different questions. Here is how to read that distinction more carefully.
Anamorelin: Approved in Japan, Rejected in Europe, and Never Approved by FDA
Anamorelin is an oral ghrelin receptor agonist and the first drug approved anywhere for cancer cachexia, but only in Japan. Here is why Europe and the U.S. said no.
Hexarelin: The Most Potent GHRP and the One Ipamorelin Was Built to Replace
Hexarelin may have been the most potent GHRP of its generation, but off-target hormone release, rapid desensitization, and a failed development path explain why newer peptides like ipamorelin replaced it.
Amycretin: Novo Nordisk's Next-Generation Obesity Drug in Oral and Subcutaneous Phase 3
Amycretin is Novo Nordisk's unimolecular GLP-1 and amylin receptor agonist, now in Phase 3 for obesity in both oral and subcutaneous forms. Here is what the trial data actually show.
SLU-PP-332: Not a Peptide, Strong Mouse Data, and No Human Trials
SLU-PP-332 is an ERR agonist sold by peptide vendors as an exercise mimetic, but it is a synthetic small molecule, not a peptide, and all efficacy data remain preclinical.

VIP peptide, or vasoactive intestinal peptide, has a real clinical literature, a controversial role in the Shoemaker CIRS protocol, and an unusual FDA Category 1 compounding status in 2026.

Cerebrolysin: Approved in 50+ Countries, Contested in Trials, and Outside the U.S. Compounding Framework
Cerebrolysin is not a single peptide. It is a porcine-brain-derived peptide mixture used in over 50 countries, backed by a large but disputed clinical literature, and awkward to place inside the normal U.S. peptide-compounding framework.
Retatrutide + Cagrilintide: Why This Stack Has Zero Clinical Trials
The mechanistic case for retatrutide plus cagrilintide is easy to understand. The clinical evidence base is zero. Here is why the stack exists, why the trial gap is probably structural, and why pre-mixed blends make verification harder.
Brenipatide Might Be Lilly's Most Overlooked Peptide Story After Retatrutide
Retatrutide gets the hype, but Lilly's investigational peptide brenipatide is being studied across alcohol use disorder, major depressive disorder, bipolar disorder, smoking relapse, opioid use disorder, and more. Here is what the official trial record actually shows.
