PEPTIDES
Peptides are all the rage these days, but it’s SO important to be cautious about where they are sourced. While I don’t believe that the most expensive version of anything is necessarily the best version, there is truth in “you get what you pay for” so I also wouldn’t buy the cheapest version either. One of the best sources for finding reputable sources for peptides is https://peptidecritic.com/. Think of it like Yelp for peptide companies. They also have a WONDERFUL discussion thread under the “Community” tab.
After over a year of sourcing, shopping around and using peptides, I settled on EZPeptides as my vendor of choice. They have a great reputation, batch specific COAs (read below for explanation), fast shipping, great customer service and I’ve had great success with their products.

Here is a brief overview of what to consider when purchasing peptides through “grey market” sources (not compounding pharmacies that are MUCH more expensive)
1. Legal and Regulatory Status
- Most injectable peptides sold on grey market sites are not FDA-approved for human use (or have been placed on Category 2 lists restricting compounding).
- They are sold with disclaimers to avoid liability, but personal importation or use can still raise legal issues, including customs seizures or violations if marketed/intended for human consumption.
- Check current FDA or equivalent regulations in your country — rules change frequently (e.g., reclassifications of popular peptides like certain GLP-1 analogs or others).
2. Purity and Quality Verification
- Demand lot-specific Certificates of Analysis (COAs) from independent third-party labs (e.g., showing HPLC, mass spectrometry results).
- Look for high purity claims (ideally ≥98–99%), but note: “Purity” tests often only confirm the main compound — they rarely detect bacterial contaminants, endotoxins, heavy metals, or residual solvents.
- Red flags: Generic/vague COAs, no batch numbers, or unverifiable testing labs. Fake COAs are common.
3. Vendor Reputation and Red Flags
- Positive indicators:
- Transparent sourcing and manufacturing details.
- Consistent positive feedback from research communities (not just marketing testimonials).
- Clear policies on shipping, returns, and testing.
- Major red flags:
- Unrealistically low prices from new vendors with no or few reviews (suggests corners cut on quality).
- Vague or hidden company info, no responsive customer support.
- Pressure to buy or lack of batch traceability.
5. Storage, Handling, and Reconstitution
- Peptides are sensitive to temperature, light, and moisture — improper shipping/storage can degrade them or make them ineffective/harmful.
- Check vendor practices for cold-chain shipping.
- Reconstitution requires sterile technique and proper diluents; errors here increase risks.
6. Other Practical Considerations
- Testing your own supply — Some users send samples for independent analysis, but this adds expense and doesn’t guarantee sterility.
- Health monitoring — Any use should involve professional oversight (bloodwork, etc.), though grey market sources provide none.
