The short version

  • The complaints cluster around price, a billing dispute, and distrust of co-founder Jay Campbell.
  • The praise clusters around testing transparency: public certificates and named labs.
  • Many complaint threads are a year or more old. Some of what they criticize, like COA access, has since changed.
  • Independent scores land in the middle: 7.0 to 7.3 out of 10 on rating sites, and a 6.41 "Band D" on PeptideBenchmark.

Where the conversation happens

BioLongevity comes up across a handful of subreddits. The main ones: r/Biohackers, r/PeterAttia, r/PeptideDiscussion, r/peptidebenchmark, r/ScienceBioTechnology, and the brand's own r/BioLongevityLabs, which has about 1,500 members.

We summarize the recurring points here rather than quoting individuals. Each thread is linked so you can read it in full.

The complaints

Price. The most common one, and it's fair. The top-ranking thread, "Stay Away from Biolongevity Labs" on r/Biohackers, opens with it. A 10mg BPC-157 vial costs $99.97. Several cheaper vendors sell it for under $50. Our catalog and prices page has the full list.

A billing dispute. The same thread describes being charged about $100 more than the order total. We can't verify individual billing cases. If it happens to you, contact support before disputing with your card issuer.

The US-made claim. Some posters doubt that synthesis happens in the US. Nobody on either side has shown evidence. What we could confirm is that finished batches are tested by three named US labs.

The founder. A good share of the negativity is about Jay Campbell personally rather than the products. A thread on r/PeptideDiscussion describes a rude reply to a COA request. Other threads call him a salesman. That's a judgment about a person. It tells you less about what's in a given vial than a certificate does.

The praise

Testing transparency. In the widely shared comparison "10 Best Peptide Companies Compared" on r/ScienceBioTechnology, BioLongevity is listed with HPLC and mass spec testing, a public COA library, and a named issuing lab.

A fallback after Peptide Sciences closed. When Peptide Sciences shut down in early 2026, BioLongevity was one of the names people moved to. The r/PeterAttia thread on the closure mentions it as a higher-quality option.

Service and packaging. Shorter first-order posts tend to praise packaging and fast shipping.

What's changed since the older threads

Some complaints describe a company that looked different a year ago. Certificates are now public before you buy. The quality page names three labs, SafeCert Labs, BioRegen and AV Analytics, and two of them let you verify a certificate on their own site.

Pricing hasn't changed much, so that complaint still stands.

Independent scores, for balance

Reddit tends to amplify the extremes. A few sites score vendors on fixed criteria. PeptideBenchmark, which grew out of r/peptidebenchmark, gives BioLongevity 6.41 out of 10 (Band D). Peptide Grades gives it a B. PeptideMind shows 4.0 out of 5 across 28 user reviews.

Our own BioLongevity Labs review confirms 3 of 3 quality claims and lists the flags we'd still raise.

Common questions

Opinion is split. Complaints focus on price, one billing dispute and distrust of co-founder Jay Campbell. Praise focuses on public certificates and named testing labs. The product-quality evidence that can be checked is mostly positive.
