Peptide Intelligence Library — education, not a storefront
Read the molecule before
you believe the hype.
A hundred-and-twenty-four compounds, read line by line — the molecules behind our products and the ones we track and teach, plus the full reference index we host so you never have to leave for the deeper read. Every profile carries an evidence grade, a plain Peppies stance, and an honest split between what people claim and what the literature actually supports. Peppies sells systems and certainty, not vials; this room is here for the days you want the receipts.
Peppies Research Supply supplies research-use-only products to verified professional accounts, alongside education, tracking, verification, and protocol support. We do not prescribe, diagnose, or replace a doctor; nothing on Peppies is sold or supplied as a medicine or for human or veterinary use, and each product’s exact status is shown on its page. Products ship with per-batch COA/SDS and a verified batch passport. Nothing here is medical advice; results vary; speak with an independent qualified professional — especially if you're pregnant, nursing, on medication, or a tested athlete (WADA rules apply to some ingredients).
21 Peppies-curated profiles + 103 reference profiles = 124 total. The reference set is our import of the public PeptideBase index (119 entries); 16 of those overlap compounds Peppies already curates in depth, so they merge into a single richer profile — leaving 103 net-new reference reads. 119 imported − 16 merged = 103.
The peptide library, by tier
In Peppies consumer products
The cosmetic-legal, consumer-grade actives that power Peppies formulas. Sold only as finished, third-party-tested products — never as vials. These carry the strongest, most directly applicable evidence in the library.
No matches in this tier.
Watchlist — education only
The compounds we track and teach so members can read the science honestly — plus the full reference index we compiled from the public PeptideBase research library and now host here, so the deeper read lives on-site. Peppies does not sell, supply, or prescribe any of these; each profile is education only — speak with an independent qualified professional about any use. Filter by goal above to narrow the list.
No matches in this tier.
Restricted — not sold
Prescription-only or investigational medicines. Peppies never sells, supplies, or prescribes these — we track and teach them for education only. Any use requires an independent qualified professional of your own choosing, where legal.
No matches in this tier.
Avoid — red flag
Compounds sold almost entirely as grey-market “research chemicals,” with no approved human use, unverified purity, and documented or unknown safety risk. Peppies does not sell or supply these and does not advise their use; they are listed here only so you can recognise the red flags and read why we steer clear.
No matches in this tier.
Profiles are educational summaries of the published literature, not medical advice or dosing instruction. Evidence grades reflect the strength of the public evidence, not a recommendation; results vary; talk to your doctor.
Research stacks.
How these compounds are studied together, and the mechanistic reason the pairings come up in the literature. Education only — no protocols, no dosing. Peppies sells systems, not stacks.
The deeper read lives here now.
Every profile links straight to its primary sources, and the full reference index — once a link off-site — now lives on these pages. Search it, filter it by goal, read the receipts without leaving.
Reference profiles compiled from the public PeptideBase research index and rewritten to Peppies' education-only standard — no dosing, no sourcing, no sales.
Compound profiles
One page per compound: what it is, how it works, the evidence, safety, legal status and sources.
Questions about the library
- What is the Peptide Intelligence Library?
- A free, plain-language education library on peppies.eu with more than a hundred compound profiles: the actives in Peppies consumer products, the compounds Peppies tracks and teaches, and a reference set rewritten from the public PeptideBase research index. Every profile carries an evidence grade, a plain stance, and a split between what people claim and what the published literature supports.
- What do the four tiers mean?
- A: actives used in Peppies consumer products. B: watchlist, compounds tracked for education only, plus the reference index. C: restricted, prescription-only or investigational medicines. D: avoid, compounds sold almost entirely as grey-market research chemicals, with no approved human use, unverified purity and documented or unknown safety risk.
- What does the evidence grade mean?
- It reflects how strong the published evidence for a compound is. It is not a recommendation to use it, and results vary.
- Does the library give dosing or protocols?
- No. Profiles summarise the published literature for education: no dosing, no protocols, no sourcing and no medical advice. Speak with an independent qualified professional, especially if you are pregnant, nursing, on medication or a tested athlete (WADA rules apply to some ingredients).
- Where does the information come from?
- Every profile links to its primary sources. The reference profiles were compiled from the public PeptideBase research index and rewritten to an education-only standard; where one overlaps a compound Peppies already covers in depth, the two are merged into a single profile.
- Which compounds have their own page?
- GHK-Cu, Matrixyl 3000, SNAP-8, Capixyl, Redensyl, Glutathione, Collagen peptides and NMN and NAD+. Each page covers what the compound is, how it works, the evidence, safety, legal status and sources.
- How do I check a product's lab report?
- Products ship with a per-batch certificate of analysis (COA). The COA library summarises the approved reports per compound, and the guide How to read a peptide COA explains what to check line by line.
