What Is Felix Chemical Supply?
Felix Chemical Supply is a New York research peptide vendor that operates online as Chem-LLC at felixchem.is. The company launched in 2022 and sells injectable research compounds to US buyers. To be clear, the site presents itself as American-owned. The brand also lists third-party lab testing for its products. Customers also reach staff by phone and email.
Review sites list the brand under two names. Peptide Protocol Wiki says Felix Chemical Supply, while PeptideMind says Chem-LLC (Felix Chemical Supply). Both names point to the same New York operation. A telehealth brand named Felix also appears in searches. Check the domain.
Who Runs Felix Chemical Supply?
The business presents itself as American-owned and operated, with its base in New York City. Public sources name no individual founder or owner. In fact, review sites describe a small domestic operation with live phone support and fast email replies. The company brands itself around US ownership and US lab testing. The focus drives most of its marketing.
The storefront has one quirk. As of 2026, catalog access requires account registration. Why does that matter? Shoppers can’t compare products and prices without handing over an email first.
What Peptides Does Felix Sell?
Felix sells injectable research peptides across growth hormone, tissue repair, and GLP-1 categories. Listed names include BPC-157, TB-500, Ipamorelin, Sermorelin, PT-141, GHK-Cu, and semaglutide. Third-party listings also show retatrutide, tirzepatide, and MOTS-c. Here’s the thing: none of these vials is an FDA-approved medicine. Labels read research only.
Sample Listed Prices:
| Peptide | Size | Price (USD) |
|---|---|---|
| Semaglutide | 5 mg (0.005 g) | $87.99 |
| Sermorelin | 10 mg (0.01 g) | $69.99 |
| TB-500 | 10 mg (0.01 g) | $69.99 |
| MOTS-c | 10 mg (0.01 g) | $59.99 |
| PT-141 | 10 mg (0.01 g) | $42.99 |
The lineup leans toward popular biohacking and weight loss compounds. Why does that matter? Those categories draw the most regulatory attention. The table below shows a sample of listed sizes and prices.
How Many Products Are in the Catalog?
The catalog holds about 52 products, priced from $7.99 to $189.99 (USD) in one review summary. The range covers small cosmetic peptides up to large weight loss compounds. Vial sizes run from 5 mg (0.005 g) to 100 mg (0.1 g). The cheapest items sit at the low end of the price scale. Larger vials cost more overall but less per milligram, so bulk buyers save.
The range isn’t the full picture. Another listing shows a 50 mg (0.05 g) retatrutide vial at $299.99. So the top price runs higher than the summary says.
Are Felix Peptides Legal and Safe?
No. Felix peptides are not FDA-approved medicines, and the vials carry research-only labeling. Medical sources call this the gray market. Sellers label products for research purposes only or not for human consumption. Buyers who inject them take on risks around dosing, sterility, and purity with no medical oversight. Experts also question product quality.
Key Safety Points:
- Research peptides lack FDA approval for wellness uses
- Vials are labeled for research only
- Contamination is a risk with unqualified sellers
- Medical supervision is the safer route
Short answer: a clean vendor record doesn’t make a research vial safe for self-use. Does a lab report fix that? Not fully, because regulators haven’t reviewed the product for human use.
Are Research Peptides FDA Approved?
No. Most research peptides lack FDA approval for anti-aging, muscle growth, or general wellness uses. Several peptide drugs do hold approval. Insulin and GLP-1 medicines like semaglutide and tirzepatide are examples. Approved brands include Ozempic, Wegovy, Zepbound, and Mounjaro. Regulated pharmacies sell those under a prescription. Doctors prescribe them.
A vendor vial labeled semaglutide is a different product. The approved brands go through manufacturing review and clinical oversight. Research vials don’t. Is the molecule the same? On paper, maybe. The regulatory standing is not.
Who Should Avoid Research Peptides?
Anyone without a clinician faces the highest risk from gray market peptides, since no professional checks source, dose, or purity. Doctors urge a talk with a healthcare provider before using any peptide bought outside regulated channels. Social posts also warn about contamination and weak research behind unqualified sellers. Risk rises without checks.
People with medical conditions face extra risk. So do people who take other medicines. The bad news? Nobody can predict how an unreviewed compound interacts with those.
Does Felix Provide Third-Party COAs?
Yes. Felix publishes third-party certificates of analysis that visitors can open without creating an account. Peptide Protocol Wiki rates COA quality at 8.0 out of 10, the highest of its eight scoring categories. Per-batch reports appear for many products, and the testing lab is US-based. Public reports are rarer than vendors admit. Buyers can verify claims.
Testing Highlights:
- HPLC purity testing
- Endotoxin testing added in November 2025
- Sterility panels advertised by the company
- US-based third-party lab
The score sits well above Felix’s own 6.8 average. What’s more, the company advertises quantitative and qualitative analysis for each tested lot.
What Tests Do the COAs Cover?
The published reports cover HPLC purity and endotoxin testing, while the company also advertises sterility panels. HPLC measures how much of a vial is the target peptide. Endotoxin tests look for bacterial contamination that can cause a harmful reaction. The company also advertises quantitative and qualitative analysis. Both tests matter for injectables.
Endotoxin testing arrived in November 2025. Few budget vendors offer it, which makes the addition stand out. Think of it this way: a COA proves a tested sample, not every vial. Does batch matching matter? Yes, because the lot number on the vial must match the report.
What Do Felix Peptides Reviews Say?
Felix reviews skew positive, with ratings from 4.4 to 4.9 out of 5 on three aggregator sites. PeptideMind shows 4.5 from 6 reviews. Peptide Critic shows 4.4 from 7 reviews. Peptide Library shows 4.9. Peptide Protocol Wiki adds a 6.8 out of 10 score, which reads as good but moderate trust. Small pools swing averages fast, so read the written comments too.
Review Themes:
| Theme | Praise | Complaint |
|---|---|---|
| Shipping | Arrives in about three days | Tracking updates are thin |
| Packaging | Padded box, light and cold protection | Wrapping tore on one bottle |
| Website | Clear product listings | Slow page loads |
Keep one caveat in mind. Peptide Library discloses that Felix may be an affiliate partner. And the review pools are small. Here’s why that matters: a handful of ratings can swing the average.
What Do Customers Like?
Customers praise fast shipping, smooth communication, and solid packaging across most written reviews. One buyer got orders in about three days and received free bacteriostatic water. Another said the products looked legitimate and properly labeled. A third buyer called the unboxing experience good. Others praised how quickly staff replied to questions.
Testing wins repeat praise too. One reviewer called Felix the best budget domestic option. Few rivals match its endotoxin testing at that price. Does testing sway buyers? Clearly, since one repeat buyer said the testing gives confidence.
What Do Customers Dislike?
Complaints center on order tracking updates, slow website loading, and minor packaging damage that never hurt the vials. One reviewer wanted more proactive communication after checkout. Another found a dented shipping box, though the vials inside stayed intact. Wrapping also tore on one bottle. None of that points to a failed product, only rough service.
One user comment adds a darker note. The reviewer says Google searches suggest the business looks sketchy, yet keeps ordering. In plain English: even happy buyers flag trust questions. Weigh that against the polished ratings.
How Much Do Felix Peptides Cost?
Felix prices most vials between $7.99 and $189.99 (USD), with larger weight loss compounds at the top of the range. The per-milligram cost drops as vial size grows. For example, listed tirzepatide falls from $8.00 per mg at 15 mg to $4.50 per mg at 100 mg. Peptide Protocol Wiki rates pricing 6.5 out of 10. Larger vials usually cost less per milligram.
Listed Price Examples:
| Peptide | Size | Price (USD) | Per mg |
|---|---|---|---|
| Selank | 10 mg (0.01 g) | $34.99 | $3.50 |
| Tesamorelin | 5 mg (0.005 g) | $42.99 | $8.60 |
| Semaglutide | 10 mg (0.01 g) | $129.99 | $13.00 |
| Retatrutide | 10 mg (0.01 g) | $129.99 | $13.00 |
| SS-31 | 25 mg (0.025 g) | $149.99 | $6.00 |
Reviewers say sale codes circulate on social media. Prices change often. Does the listed price stay fixed? Not reliably, so check the live page before ordering.
Is Felix Worth the Price?
Yes. Felix offers solid value among budget US vendors, mainly because endotoxin testing is rare at this price tier. Reviewers call it the best budget option for domestic buyers. Competitors with deeper accreditation usually charge more for similar vials. The price gap is the main draw. Free bacteriostatic water in some orders also adds to the appeal.
Value has limits, though. Cheap vials save money. Is that the real cost? No, the bigger cost is the health risk of unregulated injectables. Bottom line: low price doesn’t offset the missing FDA oversight.
How Does Felix Shipping Work?
Felix ships inside the United States only, mainly through UPS Ground, 2nd Day Air, and Next Day Air. Domestic delivery runs 2 to 5 business days. The company offers cold-pack options during summer months. One vendor listing adds free shipping on orders over $500 (USD). Buyers outside the US can’t order. Orders leave from the New York City area, per reviews.
Shipping Facts:
- Countries served: United States only
- Carrier: UPS in three speed tiers
- Delivery estimate: 2 to 5 business days
- Cold packs available in summer
New York City sits at a major logistics hub. The New York location helps explain the quick transit times in reviews. And buyers outside the US can’t order at all.
Which Payment Methods Does Felix Accept?
Felix accepts credit cards and cryptocurrency at checkout, with no other payment options listed on review sites. Peptide Protocol Wiki scores payment flexibility only 5.5 out of 10. The score ties for the weakest mark among its eight categories, level with website experience. Limited choice is a common complaint. Wallets and bank transfers are absent.
The crypto option deserves a second look. Why? Crypto payments typically can’t be reversed like card chargebacks. So buyers who pay with coins carry all the dispute risk.
How Does Felix Compare to Other Vendors?
Felix scores 6.8 out of 10 on Peptide Protocol Wiki, below several top-ranked US vendors. Great Northern Peptides leads the comparison at 8.0. AminoVault follows at 7.9, and Growth Guys Canada sits at 7.8. The gap is real, but endotoxin testing and low prices keep Felix competitive with the pack. Price still draws buyers away from pricier accredited labs.
Vendor Comparison:
| Vendor | Score | Standout Feature |
|---|---|---|
| AminoVault | 7.9 | ISO/IEC 17025 accreditation and GMP manufacturing |
| Biotech Peptides | 7.7 | Heavy metal testing and 4.8/5 Trustpilot rating |
| Eternal Peptides | 7.7 | Janoshik-verified COAs for 23+ peptides |
| Felix Chemical Supply | 6.8 | Endotoxin testing at budget prices |
Rivals win on accreditation and lab breadth. Felix wins on price per vial. Here is the part most people miss: rank depends on which factor a buyer values most. Is the lowest price the best pick? Not always.
Is Felix Legit?
Yes. Felix is a real US vendor with a moderate trust score of 6.8 out of 10 and a four-year record. Public COAs, live phone support, and consistent shipping reviews back that up. Peptide Protocol Wiki lists it as a US domestic vendor with a good rating tier. In short, Felix exists, ships, and publishes lab reports, unlike so many gray market rivals.
Legit as a business is not the same as safe or legal as a medicine. And the vendor’s own marketing leans on research-only labels. Verify current COAs and community notes before any order.
Should You Buy From Felix?
No. Felix is not a source for self-treatment, since research vials carry no FDA review or medical supervision. A buyer who wants a peptide drug needs a licensed clinician and a regulated pharmacy. Medical experts back that route and warn against gray market injectables. Every niche vendor faces this issue. Peptide drugs belong in a clinic, not a mailbox.
The vendor does earn credit for transparency. Public COAs, endotoxin testing, and fast domestic shipping beat many rivals. Honestly, those strengths only matter to qualified researchers with a legal use.
Is Felix Peptides Worth It?
No. For personal use, Felix isn’t worth the health and legal risk, however low the prices run. A licensed laboratory researcher gets a different answer. For that buyer, Felix offers budget pricing, public COAs, and quick US shipping. The vendor itself is competent. The use case is the problem. Others fare better with a prescriber and a licensed pharmacy.
Bottom line: Felix scores a solid 6.8 as a vendor. Felix does not score as a safe medicine source. Those are two separate questions, and the second one decides the verdict.
