Most BPC-157 (also known as PDA peptide) suppliers make remarkably similar promises. Nearly every product page mentions high purity, independent testing, fast shipping, and research-grade quality.
The meaningful differences become apparent only when you look beyond the marketing language.
Some vendors provide a single small vial. Others offer several quantities. One supplier may publish a standard purity report, while another provides separate documents covering purity, sterility, and endotoxins. Prices also vary considerably once you calculate what each milligram actually costs.
For this comparison, we evaluated three established research suppliers:
- BioInfinity
- Limitless Biotech
- Sports Technology Labs
BioInfinity is our preferred overall option, largely because it offers the broadest selection of vial sizes at the lowest standard price per milligram. Limitless Biotech is the strongest choice for buyers who place the greatest importance on extensive testing documentation, while Sports Technology Labs provides a straightforward 5 mg option with clearly presented third-party results.

The Quick Recommendation
- Choose BioInfinity when: You want a choice of 5 mg, 10 mg, or 20 mg vials, competitive pricing, a current batch-specific COA, and domestic same-day shipping.
- Choose Limitless Biotech when: You want separate purity, sterility, and endotoxin reports or need a larger 10 mg or 20 mg vial.
- Choose Sports Technology Labs when: You want one 5 mg vial from a supplier that clearly identifies its outside testing laboratory and publishes the current COA without requiring an account.
#1. BioInfinity: The Best All-Around Option
Click Here Now to see Bioinfinity’s page on PDA (BPC-157) peptide to learn more.
BioInfinity is the easiest supplier to recommend to the largest number of researchers because it performs well across price, quantity selection, testing, and shipping.
The company currently offers three BPC-157 sizes:
- 5 mg for $40
- 10 mg for $80
- 20 mg for $160
That creates a simple and consistent base price of approximately $8 per milligram, regardless of vial size.
The company also applies quantity discounts. Orders of three to five units receive a 15% reduction, while purchases of six or more units reduce the listed price of a 5 mg vial from $40 to $32.
What BioInfinity Does Particularly Well
The current product page does more than make a general company-wide purity claim. It identifies the batch being offered, the testing date, the analytical laboratory, and the methods used.
At the time of review, BioInfinity displayed a current result of 99.89% purity. The batch was analyzed by Verum Analytics using HPLC-UV/MS, and the corresponding Certificate of Analysis was accessible directly from the listing.
This presentation makes it relatively easy to connect the product being sold with the analytical documentation provided for it.
BioInfinity also offers more flexibility than the other two companies in this comparison. Someone who requires only a small amount can select 5 mg, while larger projects can use the 10 mg or 20 mg options without ordering multiple small vials.
Price Is Its Biggest Advantage
The standard $8-per-milligram price is lower than the comparable cost from either Limitless Biotech or Sports Technology Labs.
That difference becomes more noticeable with larger quantities. A 20 mg BioInfinity vial is currently listed at $160, whereas the 20 mg option from Limitless is listed at up to $180.99. Sports Technology Labs offers only a 5 mg vial at $59.99.
BioInfinity therefore wins this comparison not because it is merely the cheapest company, but because the lower price is accompanied by visible batch testing and several quantity choices.
Shipping and Availability
Orders submitted before 2:00 p.m. Eastern Time from Monday through Friday are eligible for same-day processing. Standard UPS Ground shipping is listed at $7.99, and orders of at least $200 qualify for free two-day shipping.
BioInfinity currently delivers to all 50 states but does not offer international shipping.
What to Consider Before Ordering
BioInfinity’s published documentation focuses primarily on identity and purity testing. Researchers who specifically require separate sterility and endotoxin reports may find Limitless Biotech’s documentation more suitable.
The lack of international delivery is also a clear limitation for buyers outside the United States.
Best Suited For
BioInfinity is the strongest option for buyers who want:
- Several vial sizes
- A low and predictable cost per milligram
- A visible batch-specific COA
- Independent HPLC and mass-spectrometry testing
- Fast domestic shipping
#2. Limitless Biotech: Best for Extensive Testing Records
Click Here Now to see Limitless Biotech’s page on PDA (BPC-157) peptide to learn more.
Limitless Biotech takes a different approach. It is not the cheapest supplier in this comparison, but it publishes the broadest collection of testing documents.
Its BPC-157 is currently offered in 10 mg and 20 mg quantities, with listed prices ranging from $99.99 to $180.99.
Automatic discounts are available for larger orders:
- Five to nine units: 5% off
- Ten to fourteen units: 10% off
- Fifteen or more units: 15% off
The Documentation Is the Main Selling Point
Limitless publishes separate laboratory reports addressing:
- HPLC purity
- Sterility
- Endotoxin levels
The product page contains reports for several different batches, including documentation for both 10 mg and 20 mg products.
This matters because those reports do not all answer the same question.
An HPLC result estimates how much of a sample corresponds to the target compound. It does not, by itself, establish sterility or show whether bacterial endotoxins are present. Researchers whose protocols require those additional measurements may therefore find the Limitless documentation more useful than a purity report alone.
A Small Inconsistency Worth Noting
The technical specifications list BPC-157 at at least 99% purity by HPLC. However, the summary near the top of the page describes a broader company standard of at least 98.5%.
That does not necessarily mean the BPC-157 fails to meet the higher specification, but the two statements should ideally be presented more consistently.
Price Compared With BioInfinity
The 10 mg option starts at $99.99, which equals approximately $10 per milligram.
The 20 mg option at $180.99 works out to roughly $9.05 per milligram. This is a better per-milligram value than the smaller Limitless vial, but it remains higher than BioInfinity’s standard rate of approximately $8 per milligram.
Limitless is therefore less compelling as a pure value choice. Its advantage lies in the additional testing records rather than the lowest purchase cost.
International Availability
Limitless can ship to numerous destinations outside the United States.
International customers are responsible for confirming that the product can legally be imported into their country. The company does not guarantee customs clearance and states that it cannot provide refunds or replacements for packages affected by customs seizures, refusals, or other import restrictions.
Return requests must generally be initiated within 10 days of delivery.
Best Suited For
Limitless Biotech makes the most sense for buyers who want:
- Separate purity, sterility, and endotoxin reports
- A 10 mg or 20 mg quantity
- Multiple batch documents to review
- International shipping availability
- Greater emphasis on documentation than on obtaining the lowest price
#3. Sports Technology Labs: Best for a Straightforward 5 mg Purchase
Click Here Now to see Sports Technology Labs page on PDA (BPC-157) peptide to learn more.
Sports Technology Labs offers the simplest product selection of the three companies.
There is one BPC-157 option: a 5 mg vial priced at $59.99.
That lack of choice can be a disadvantage for larger projects, but it also makes the purchasing decision uncomplicated. There are no different strengths or quantities to compare.
Clear Third-Party Testing Presentation
The current batch is listed at 99.43% purity by HPLC.
Sports Technology Labs identifies MZ Biolabs in Tucson, Arizona as its testing partner and states that the product was evaluated for identity, purity, and concentration. The company also reports using mass spectrometry to verify the listed peptide identity.
The COA is available online without requiring an account, email submission, or request to customer service.
That accessibility is one of the company’s strongest qualities. A buyer can review the current report before placing an order rather than relying on a generic promise that documentation will be supplied later.
The Main Drawback Is Cost
At $59.99 for 5 mg, the standard price works out to approximately $12 per milligram.
That is about 50% higher than BioInfinity’s standard $8-per-milligram price. It is also higher than the approximate per-milligram cost of either Limitless vial.
A buyer is therefore paying more for a smaller quantity.
The price may still be acceptable for someone who wants only one 5 mg vial and values the clear testing presentation, but it is less attractive for research requiring larger quantities.
You can see a side-by-side comparison of the pricing in the table below:
| Supplier | Example Quantity | Listed Price | Approximate Cost per Milligram |
|---|---|---|---|
| BioInfinity | 5 mg | $40 | $8.00 |
| Limitless Biotech | 10 mg | $99.99 | $10.00 |
| Limitless Biotech | 20 mg | $180.99 | $9.05 |
| Sports Technology Labs | 5 mg | $59.99 | $12.00 |
Shipping and Returns
Sports Technology Labs currently ships only within the United States. Orders are normally dispatched within one business day, and domestic delivery generally takes three to five business days.
Free shipping begins at $149, and unused products can be exchanged within 60 days of purchase.
Best Suited For
Sports Technology Labs may be the right choice when the priorities are:
- A single 5 mg vial
- A clearly identified U.S. testing laboratory
- Easy access to the current COA
- HPLC purity and mass-spectrometry identity testing
- A longer exchange period for unused products
PDA Peptide and BPC-157 Naming
For the purposes of this guide, PDA peptide refers to BPC-157.
The three products compared here are sold under the BPC-157 name. Their technical listings identify the standard 15-amino-acid sequence:
Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val
Researchers should still verify that the product name, sequence, amount, and batch information shown on the COA match the vial being purchased.
How We Reached the Ranking
The ranking was based on the buying experience as a whole rather than selecting whichever company displayed the highest purity percentage.
We considered:
- Whether the current batch could be connected to a published COA
- The kinds of tests included in the documentation
- The available quantities
- Standard cost per milligram
- Domestic and international shipping availability
- Return or exchange terms
- Whether product information could be reviewed before creating an account
BioInfinity ranked first because it provides the strongest balance across all these categories.
Limitless ranked second because its documentation is the most extensive, although its prices are higher.
Sports Technology Labs ranked third because its testing presentation is strong, but the single 5 mg size and higher price per milligram limit its overall value.
