Peptide Pros review

Peptides Sold by Peptide Pros

Now, let’s explore the Peptide Pros catalog. Here are the top three peptides available:

Peptide Pros BPC-157

This pentadecapeptide, also called Body Protection Compound-157, is synthetically derived from an organic compound present in the gastrointestinal tract, called Body Protection Compound. The peptide is key to healthy digestive functioning, as it works to heal lesions of the GI tract while fortifying and calming the lining [1]. It shows therapeutic potential in a range of contexts, including addressing inflammatory disease symptoms, boosting tissue growth, speeding wound healing, and neuroprotective effects [2, 3, 4, 5].

Peptide Pros TB-500

This synthetic peptide is an analog of the actin-modulating compound thymosin-beta 4, which has angiogenic effects and works to enhance cellular repair and regeneration in most types of animal cells [6]. It is being closely studied for its safety and potential in a range of therapeutic uses, including improved cardiovascular health, anti-aging, countering symptoms of inflammatory disease, and injury recovery [7, 8].

Peptide Pros Melanotan 2

This peptide analog of alpha-melanocyte-stimulating hormone (α-MSH) is also being studied for its potential efficacy in numerous clinical contexts. These include darkening of the skin through melanogenesis, stimulating sexual arousal, countering symptoms of erectile dysfunction, attenuating addictive and obsessive behavioral patterns, and enhancing body composition. It has a good safety rating to date [9, 10, 11].

Peptide Pros also carries the α-MSH derivatives Melanotan 1 and PT-141, anti-aging peptides including GHK-Cu and epithalon, and the following growth hormone secretagogues:

Payment and Shipping

The Peptide Pros website provides safe payment via multiple security measures, including SSL encryption with a McAfee Secure Certification. However, the accepted payment methods are limited to these options:

  • Electronic check
  • Bitcoin (5% discount)
  • Money-order or check sent by mail

Given the contested space and evolving regulations of payment practices in this industry, it’s worth noting that this vendor states that a separate company name will show on bank statements. Peptide Pros is a DBA of an LLC that appears to be a shipping supplies vendor.

The company shipping details are as follows:

  • Deliveries are performed via USPS with tracking numbers
  • International deliveries are available, however, shipping to certain countries as well as the state of Hawaii is not offered
  • Domestic orders over $150 are shipped free of charge
  • Orders are processed within 24 hours
  • Certain Designated products (marked “USA only”) are not eligible for international shipping due to legal restrictions

Returns are not accepted, though the vendor offers to resend lost products without charge. It also states that products tested below 99% purity are eligible for replacement. Lastly, Peptide Pros has a customer rewards program with points redeemable towards both products and shipping.

Benefits of Buying from Peptide Pros

There are some benefits to buying from Peptide Pros. The vendor’s best features include the following:

Evidence of Quality Assurance Protocols

Peptide Pros claims to perform third-party lab testing to establish the high purity levels advertised. Many product listings include certificates of analysis and test results that appear to be valid. It also has a quality guarantee, stating that it will replace products tested below 99% if clients can furnish proof.

A Range of Peptides and Chemicals is Offered

Peptide Pros has a relatively wide range of chemicals and peptides in comparison to competitors. The research peptide catalog includes many varieties, from growth hormone secretagogues to melanogenic and anti-aging compounds.

Competitive Prices With Many Discount Offerings

Prices fall on the lower side, and the vendor offers numerous discounts via coupons, sales on select items, and bulk price breaks. The discounts available to wholesale buyers are comprehensively listed for client convenience. Plus, buyers receive an automatic 25% discount upon registering on the website.

Lucrative Customer Rewards Program

In addition to regular deals, Peptide Pros has a generous rewards program that garners 10% back all purchases for registered clients. It also grants access to members-only discounts and rewards points that can be redeemed on both products and shipping charges.

Secure Check-Out

The Peptide Pros website is highly secure with several protection measures in place. Security mechanisms include SSL encryption, Secure Lock verification, Norton Shopping Guarantee, and McAfee Secure Certification.

Downsides of Buying from Peptide Pros

Now that we have covered the benefits, we will explore the primary drawbacks to patronizing Peptide Pros. These items have weighed heavily in our final valuation of the company:

Concerns Over Lab Testing and The Availability of Test Results

While Peptide Pros advertises that its testing features both HPLC and MS analyses in accordance with the highest pharmacological standards, the test results provided on the website show otherwise [12]. Available results evidence the performance of MS and UV analyses, not HPLC. The incongruency is disquieting considering that UV analysis is considered by experts to be a less accurate method than HPLC. UV analysis is cheaper and quicker to perform, but yields less reliable results [13]. Given this, the quality reports may be erroneous, raising concerns over the efficacy and safety of the available products [14].

Further, certificates of analysis are not available on all products listed on the website. We noticed that all product listings do have a COA link; however, in many cases, this link simply refreshes the page, and no certificate of analysis is provided.

Limited Forms of Products

Leading retailers offer products in numerous states, from powders to liquids and topicals. However, the Peptide Pros catalog is limited to peptides in powder form and research chemicals in liquid vials.

Not Many Payment Methods Are Accepted

Peptide Pros does not accept standard payment methods, which may inconvenience potential clients. Plus, of the three options available, one is sending a check through the postal service, which greatly delays the transaction.

Limited International Shipping

While the retailer advertises domestic and international shipping, the fine print reveals that there are significant exclusions. For example, it does not ship to the US state of Hawaii, or numerous countries, including the UK, Germany, Denmark, and India.

Room for Improvement on Website Content

As mentioned above, there are some inconsistencies in the information provided on the website. Aside from false testing claims, we noticed conflicting shipping rates, a lack of clarity on payment methods, and uninformative product listings.

Peptide Pros Reviews From Researchers

Don’t take our word for it! Let’s take a look at what some customers of Peptide Pros have to say about the company.

This client was satisfied with their experience buying from Peptide Pros:

“Very pleased with timing of ordering to shipping, quality of product seems to be high as well. Recommended to colleagues.” [15]

However, we found numerous low reviews with repeating claims, such as:

“I ordered a vial of PT-141. It came without the purified water needed to reconstitute and no instructions or dosing information. This may be why their pricing is lower than others. Also the fact that they don't accept credit or debit cards for payment is telling. It's much harder to submit a claim with just a bank payment. I'll never order from them again.” [16]

Is Peptide Pros Legit?

Unfortunately, we can’t definitively say the Peptide Pros is legit. While the vendor is certainly more credible than some competitors, it does not rise to meet all the quality standards agreed upon by experts in the scientific arena. We appreciate its many positive reviews, secure website, and efforts at quality control. However, these issues detract from the brand’s overall legitimacy:

  1. Quality assurance testing does not meet the highest standard.
  2. Quality assurance test results are not available on all products, and the website may be designed to misrepresent this fact.
  3. There is a trend of client reviews citing low-quality products.
  4. Traditional payment methods are not accepted, and alternative methods are limited.
