Where to buy VIP (also sold as Vasoactive intestinal peptide): the 4 vendors below are the ones we have a dated product-page price for, ranked on documentation first and price second. Nothing here is typed from memory — every number links to a date.
Research use only. Compound Review scores vendors on documentation — laboratory certificates, lot records, pricing and company identity. Nothing on this page is guidance on human or veterinary use, dosing or health outcomes.
Reference size 10mg — the size most of these vendors sell. Other sizes we have on record are listed per vendor.

VIP (vasoactive intestinal peptide) is a 28-residue peptide that fewer vendors stock than most compounds on this site, and some of those that do listed it as out of stock when we read the page. It is longer than the average research peptide, more expensive to synthesise, and less stable once reconstituted, all of which show in the price and in the availability notes on this page.
It is also sold as a pre-made nasal solution by some vendors; those listings are priced by volume and are excluded from this table, which covers lyophilised vials only.
Because so few vendors carry it, this is a page where a vendor's documentation score does more work than usual — there is not much of a price comparison to make. Availability at the time we read each product page is noted per vendor.
What we can verify
Publishes per-lot COAs naming the testing laboratory — SteriGenix and Freedom Diagnostics — with lot numbers, test dates, measured net peptide content and direct verify-at-lab links. HPLC and mass spectrometry testing, US-based fulfilment from Scottsdale, Arizona, same-day dispatch on weekday orders before 2PM EST, and a 60-day money-back guarantee.
Net content: Measured net peptide published per lot (e.g. BPC-157 lot PL-BPC-05: 11.16mg vs 10mg label)
Where it falls short
Smaller independent review base than several competitors (80 reviews). The catalog is peptide-focused, so researchers also working with SARMs or broader research chemicals will need a second supplier.
What we can verify
Names Janoshik Analytical and Vanguard Laboratory; certificates resolve on the lab's own domain (verify.janoshik.com). Product pages list dated batch codes for previous certificates, no account required. Legal entity, Tampa, FL address, EIN and sales-tax number published: Plainview Commerce LLC. Full basket with sized pricing, stable across reads.
Net content: Vanguard Laboratory PDF for lot PG-5101 (TB-500 5mg) reports 4.92mg measured vs 5mg, 99.30% purity — read 6 Sep 2026
Where it falls short
Small review base (65 on Trustpilot, 26 Sep 2026). Measured net content could not be read from the certificate images. The legal entity name appears on the refund policy but not the About page. GLP products sold under house codes PG-1SG / PG-2TZ / PG-3RT.
What we can verify
Names North American Diagnostics, and the lab's own portal returns the record for test ID NAD-0037963 (BPC-157, lot PSP-09112026BP, 99.97%, 4.88mg on a 5mg label) — looked up 3 Oct 2026. 59 certificates downloadable without an account, sized pricing across the widest GLP range we cover, card checkout (Visa/Mastercard/Amex/Discover, Afterpay, Klarna). The September '5-star from thousands' blog claim is gone, so the clean-record point is now awarded.
Net content: Measured mass vs label published (4.88mg on a 5mg label on NAD-0037963, 97.6%; 5.03mg on PSP-0028020 in Sep)
Where it falls short
Home and about pages claim 'cGMP-certified facilities' and 'accredited laboratories' while the vendor's own legit post says cGMP certificates do not exist, and no accrediting body is named. The ProSupply Services LLC name we read in September is no longer printed anywhere; 'New Jersey-based' only, no address, email-only support. Trustpilot 4.3 is still the low end of the partner set.
Purgo Labs sits at #1 of 4 on this page: 10/10 on the rubric, 10mg at $47.99 read 23 Sept 2026. Code HEALTH gives 20% off every order. We earn a commission; it did not decide the order above.

A ranking tells you which vendors have good practices; it cannot tell you about the specific vial you receive. When your order arrives, compare the batch number on the label to the certificate. If they do not match, or there is no batch number, the documentation does not cover what you were sent, regardless of who you bought from. How to read a peptide COA.
As of 23 Sept 2026, 4 of the 77 vendors on our scoreboard list VIP with a price we have read on the product page: Purgo Labs, Peptide Giants, PS Peptides, Puratek Peptides. Every one of them is scored on the same 10-point rubric; the table above shows the score, the dated price and what you can verify before ordering.
At the 10mg size, the lowest price we have on record is Purgo Labs at $47.99 (read 23 Sept 2026) — sale; list $59.99 struck; sold out when checked. It scores 10/10 on documentation. Price is the second sort key on this page, not the first, because an underdosed vial at a low price is the most expensive outcome.
Purgo Labs and Peptide Giants share the top score at 10/10: named laboratory, certificates that resolve on the laboratory's own site, measured milligrams against the label, and a published legal identity. The per-criterion evidence, with dates, is on each vendor's review page.
VIP is sold by these vendors as a research chemical for laboratory use, not for human consumption; none of it is FDA-approved in this form. Legality of purchase varies by jurisdiction and the compound, and it is your responsibility to know your local rules. Our pages assess documentation and pricing; they are not legal or medical advice.
Rubric score first. Among equal scores, the lower verified price per milligram at 10mg. Then the larger independent review base. Affiliate partnership is not an input: 4 of the 4 vendors here are partners and they sit wherever the evidence puts them.
It is a longer peptide than most research compounds, which makes it more expensive to synthesise and more prone to purity problems, and demand is lower than for the popular healing and metabolic peptides. Vendors that stock it often run out.
No. A spray is priced by volume and its peptide content depends on the stated concentration, which the certificate may not verify. This page compares lyophilised vials with a stated milligram amount.
