Nootropic Source

Listed on r/Nootropics' unreliable-vendors list, and a February 2026 report describes a paid Canadian BTC order left unshipped, says non-US orders sit in processing for months, and points to a lookalike domain; its COAs are its own undated or unattributed certificates. Ships to France for €31. The FAQ says international First Class and Priority rates are calculated at checkout, and international orders take one extra business day to dispatch; $35 is the checkout's 'International Shipping' rate to Paris for a single item. Non-US buyers pay by crypto or bank wire.

Semax Polska

Each product shows an Analiza Białek (Wrocław) HPLC report naming its operator Dobre Peptydy sp. z o.o. as the client, with a verification password (Semax 60 mg: 62.18 mg, 99%), and Reddit buyers since 2024 report fast, professional deliveries; the only complaints are about felt effect. Ships to France for €14, 1–5 days. Ships by UPS from Poland, same day for orders placed by 11:00 CET; the rate appears at checkout and is 'usually around' €14 for the EEA, delivered in 1–5 working days. Free shipping over 200 zł applies only within Poland. Refund if the parcel is not delivered within 30 days.

Baltic Peptides

Public Janoshik reports name it as the client (e.g. #225102, Retatrutide 10mg, 99.485%), but since September 2026 buyers report parcels stuck for weeks, support that stops answering and seized packages, and the domain only dates from November 2025. Ships tracked from Lithuania; free EU shipping over €150. The shipping page states no standard rate or delivery time.

XL Peptides

Janoshik reports name XL Peptides as the client (37 read by The Peptide Watch, e.g. Retatrutide task #148206), but it has only a handful of Reddit buyer reports, so its track record is limited. Ships to France for €18, 3–7 days. Fixed £15 postage to Europe by a courier that varies by country, posted the same or next weekday from the UK; delivery estimate 3–7 business days. Customs seizures are not refunded.

Europa-Peptide

Copycat domains impersonate the shop, and a buyer says a YouTuber's bad test came from a fake Europa store; it also publishes no independent lab reports, and buyers report cloudy batches with replacements that took months. Ships by DHL from an EU fulfilment centre (buyers say Poland; the operator is a London-registered company). Delivery within Europe takes 2–5 business days according to the shipping policy and 2–9 according to the FAQ. No tracking number is given. No price is stated.

SwissChems

Several 2026 Reddit reports say it now sells fake or bunk product (MK-677, MT2, T3), one buyer says support tried to intimidate him, and another says it deflects COA requests for untested products; its Freedom Diagnostics certificates do not outweigh the fake-product reports. Ships to France for €45, free over €270, 14–21 days. USPS International, 2-3 weeks, alternative courier on request; $49.95 is the checkout's flat rate to France. Seized packages are not refunded or reshipped, only a 30% discount is offered.

Particle Peptides

Its 'independent' lab Liquilabs is a 2024 shell owned by a Slovak, and its COAs reuse HPLC serial numbers seen on an unrelated US vendor's reports; one even shows a 10 mg vial assaying 8.45 mg. Ships to France for €16, 1–2 days. Ships from Slovakia. France costs €16.00 by DHL Express or service point (1–2 days) or €18.50 by DPD (3–4 days), both before VAT. No free-shipping threshold is stated.

Modern Peptides EU

Its About page copies a US company's story word for word ('Modern Research LLC… Southern California'), so it trades on another brand's identity; its batch figures link no lab report and no independent user reports exist. There is no shipping page. The homepage says orders over 300 ship free in the EU (no currency stated; store prices are in EUR) and that expedited shipping is available. Where it ships from is not stated.

Research notes, not medical advice.

Sequence

The peptide's chain of amino acids from its start (the N-terminus) to its end, one bead and one letter for each: A alanine, C cysteine, D aspartic acid, E glutamic acid, F phenylalanine, G glycine, H histidine, I isoleucine, K lysine, L leucine, M methionine, N asparagine, P proline, Q glutamine, R arginine, S serine, T threonine, V valine, W tryptophan, Y tyrosine. A modification such as an N-acetyl cap or a C-terminal amide changes how long it lasts in the body. Length tells related peptides apart, from a two-residue dipeptide like carnosine to a 43-residue protein like thymosin beta-4, and predicts neither effect nor safety.

Report grades

Every first-hand Reddit or X report is graded on its own, from glowing through positive, mixed, nothing and negative to bad reaction, and the bar shows how those grades split. Posts that look vendor-adjacent stay on the peptide's page but are left out of the counts.

GlowingPositiveMixedNothingNegativeBad reaction

% positive

The share of a peptide's graded Reddit and X reports that are glowing or positive, vendor-adjacent posts left out. A peptide with few reports is pulled toward the average of all reports, as if it had eight average ones besides its own, so two glowing posts cannot top the list. Peptides rank by this figure, those with no graded report yet after those with one, and Avoid ones after every other entry.

Researcher estimate

No first-hand report of this peptide has been graded yet, so the figure is the researchers' own rating out of 10 from what they read about it. It ranks after every peptide with graded reports until its own arrive.

Safety tier

Each peptide is tiered Clean, Caution or Avoid from its five risk axes under the chosen safety bar. An Avoid peptide carries a real risk of harm, a plausible route to serious harm rather than mere unpleasantness, so it stays listed with the reason but ranks behind every other entry, however good its reviews.

Safety bar

The safety bar sets how much risk it takes to rate a peptide Avoid. Strict: out on any serious mechanism with little human data, or any documented serious harm. Balanced: out on documented serious harm (unless it is obvious, reversible and from a regulated product), or a serious mechanism whose harm would be silent with no human data at all. Evidence only: out only on documented serious harm in humans that is lasting, delayed or from grey-market product.

Seen harm

Documented serious adverse events in humans, from 0 for none despite real exposure to 3 for deaths or several well-documented serious harms. Serious means a hospital or emergency visit or harm lasting weeks, so a headache or a bad night does not count.

Mechanism

A plausible biological route to serious harm at the doses people use, such as growth-factor signalling, hormone-axis suppression, heart or blood-pressure effects or immune activation. It runs from 0 when none is known to 3 when a dangerous pathway has been shown in living animals.

Data gap

How little human safety data exists for the molecule actually sold, from 0 for an approved drug with large trials and years of use to 3 for no human safety data at all. A modified analogue does not inherit its parent's trials.

Silent harm

Whether the feared harm would show quickly or stay hidden, from 0 when it is obvious and goes on stopping to 3 when it is silent and delayed, like tumour promotion or slow organ damage. User reports cannot reveal a harm that takes years to appear, so a high score here limits what good reviews can tell you.

Product

The risk of what people actually buy, from 0 for a regulated pharmacy or supplement product taken by mouth or on the skin to 3 for a grey-market injectable. In one dataset of 6,441 grey-market samples, 42–71% failed basic quality criteria and 15% carried endotoxin; taken by mouth or in the nose, a pack avoids the injection risks.

Evidence

The strongest kind of study behind the peptide's effects, from an approved drug through human controlled trials and small human studies to animal work or nothing of its own. Animal results often fail to carry over to people.

Access

How people get it: as an approved drug, a compounded prescription, an over-the-counter supplement or from the grey market, where nobody checks the vial. The channel decides both the legal position and the risk of a bad batch.

Price per month

Thirty days of the typical dose, from its low end to its high end, priced at the listing a careful buyer would choose: in stock, from a shop scoring 4 of 5 on trust (third-party tested where no score is set), failing that 3, a pure pack before a blend, a European shop first, then the cheapest per mg. The range is the dose's, not the shops'. A per-dose amount counts once a day unless the dose says otherwise. The shop table keeps each listing's price per mg, per gram for bulk supplements. Where no listing can be priced the researchers' own estimate stands in, and says so.

Dose users report

The middle half of the daily doses stated in at least five first-hand reports, vendor posts left out. Where its middle sits more than twice above or below the declared dose, the month is priced at it as well, since what people take is what they pay for.

Shop trust

Each shop's trust on a 1–5 scale, read from its testing and its reputation: 1 for serious red flags (fabricated COAs, scam reports, impersonation, a closed shop), 2 for no public testing, a new shop or active complaints such as seized parcels, 3 for its own COAs or a short track record, 4 for verified third-party testing or a strong reputation, and 5 for third-party batch reports that name the shop, with years of good independent reputation. A shop without a score counts third-party batch testing as 4, its own COAs as 3 and no public tests as 2.

Best value

Within a category or a goal, a peptide that no other beats on both counts: none is rated more positively for the same or a lower monthly price, and none costs less for the same or a higher rating. The chart joins these into the best-value line; the cheapest of them and the best-rated of them both make it, so the line spans the trade-off from cheap to best. Avoid entries never count, and a peptide needs both a % positive and a price to be compared.

Testing

Whether the shop publishes lab results: third-party tested means an independent lab checks each batch, own COA means the shop's own certificate of analysis, and no public tests means neither. A certificate shows purity, not safety.

Added peptide

Some packs sold under one peptide's name hold a second one, such as 5 mg GHK-Cu in a nasal kit, stated only in the description. Sprayed in the nose or injected it reaches the blood like an injection, so it carries the risk of that route and is tiered as the injectable form, whatever its tier on the skin. A pack whose page gives no contents list may hold more than its name.
