Who is Top Peptides?

Top Peptides is an online research chemical and peptide vendor based in the USA. The Top Peptides selection includes a range of product types, such as:

  • Peptides in both liquid and powder forms
  • SARMs
  • Nootropics
  • Syringes, vials, and bacteriostatic water

There is little information available online about this company, even on its sparse website. Payment options are extremely lacking, and shipments are available only within the United States. The website states that orders are limited to one daily per customer, suggesting a non-client-centered approach.

Reviews of Top Peptides are mixed. While there are some good features, this vendor scores low ratings overall when it comes to the markers of quality that experts agree upon. Read on to learn what can be expected from Top Peptides, as well as how to choose a better option.

Peptides Sold by Top Peptides

The Top Peptides catalog includes various research chemicals and peptides. These are the top 3 peptide products available on the site:

Top Peptides BPC-157

Body Protection Compound-157 (BPC-157) is a pentadecapeptide present in GI fluid. It is angiogenic and protects the gastrointestinal lining for healthy digestion, speeding the healing of wounds and calming inflammation [1]. Studies indicate the peptide’s therapeutic potential in safely aiding injury recovery, stimulating tissue growth, treating inflammatory disease, and neuroprotection [2, 3, 4, 5].

Top Peptides TB-500

A synthetic iteration of thymosin-beta 4, TB-500 mimics the titetreconpeptide that upregulates actin and increases angiogenesis to promote cell turnover and repair in most animal cells [6]. Clinical studies indicate its therapeutic potential in boosting cardiovascular health, promoting injury recovery, anti-aging, and combating inflammation. It has a strong safety profile to date [7, 8].

Top Peptides Melanotan 2

A synthetic analog of alpha menalocyte-stimulating hormone (α-MSH), Melanotan 2 acts on the body’s melanocortin receptors to give the skin a tanned appearance, relieve symptoms of ED, stimulate sexual arousal, lessen certain behavioral problems, and boost lean muscle mass. It is considered safe in qualified settings [9, 10, 11].

Top Peptides carries other α-MSH derivatives like melanotan 1 and PT-141, anti-aging peptides like GHK-Cu and epithalon, and potent growth hormone secretagogues like:

Payment and Shipping

Payment options are limited and do not inspire confidence. While the website indicates that it uses SSL encryption, many client reviews cite breaches of security and unsatisfactory payment practices.

Top Peptides does not accept credit or debit cards. Payments are limited to these alternative methods:

  • Zelle
  • Bitcoin
  • Cashier’s check
  • Money order
  • Amazon Gift Card (limit $150)

Shipping is as follows:

  • Orders are shipped within 24 hours of payment on business days.
  • Deliveries are made with trackable USPS Priority within a window of one to four business days.
  • There is a flat shipping rate of $10 with free shipping on orders over $99.

All sales are final, except in the case of an incorrect order. The company claims no liability for lost or missing packages.

Benefits of Buying from Top Peptides

There are some positive features to buying from Top Peptides, such as:

Product Variety

The Top Peptides catalog includes a decent range of research peptides in both powder and liquid forms. The research chemical selection includes several types of nootropics and SARMs.

Informative Descriptions of Peptide and Chemical Uses

Each product is listed with a concise and well-written account of the compound’s properties and potential applications.

Frequent Markdowns and Discounts with Coupons

There are regular discounts on select products, and the website advertises frequent sales, as well as coupons with client registration.

Fast Domestic Shipping That is Free for Large Orders

Orders are said to arrive within one to four business days, and those over $99 are shipped without charge.

Downsides of Buying from Top Peptides

While we appreciate the good features of Top Peptides, there are numerous significant drawbacks. These include the following:

No Quality Claims or Assurances on Any Available Products

The vendor makes no claims as to product purity or the legitimacy of production practices. There is no discernable testing performed to establish product quality, which could present a safety hazard. [12]

No Manufacturing Location Cited

Though the company website features a banner touting “USA Peptides for Sale,” this is potentially misleading. While the business is headquartered in Tampa, Florida, there is no evidence of the manufacturing location. This indicates that products may be manufactured in countries with less stringent quality control standards than those in the United States.

Extremely Mixed Reviews

Client reviews on independent websites are somewhat polarized, with some extremely satisfied clients and others citing grave concerns. While a variety of experiences is to be expected, the drawbacks raised are significant, including breaches of payment security, little to no customer service, and even empty packages received with no rectification.

Few Payment Options

Top Peptides does not accept standard payment methods such as credit or debit cards. Only a handful of alternative methods are available, which can make checkout difficult for many clients.

No International Shipping and Limited Daily Orders

In comparison to leading online vendors, Top Peptides falls short with deliveries to clients only in the USA. This is not made entirely clear on the website until checkout. Further, there is an unusual disclaimer at checkout that clients cannot exceed one order per day.

Top Peptides Reviews from Customers

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

First, let’s hear from one of the vendor’s satisfied clients who posted this review on Trustpilot:

“This company is outstanding! Consistent quality, good prices, great choice in products. I recommend!” [13]

There are also some very low reviews, such as this one from another Trustpilot user:

“FINALLY received my package today and it was empty with only a packing slip. Do NOT do business with Top Peptides…There is NO customer service whatsoever and they make no attempt to rectify their wrongs.” [13]

Is Top Peptides Legit?

We do not recommend Top Peptides as a legitimate online source for research chemicals and peptides. The little credibility that we lend the company is in the number of positive reviews on independent websites. However, according to our expert criteria as applied to the company website, it lacks legitimacy in these crucial areas:

  • No verified testing or quality control concerning product purity or safety
  • Unclear manufacturing origins
  • Only a handful of alternative payment methods accepted
  • Highly concerning client complaints of poor customer service

Additionally, while the vendor does have social media accounts with small followings, it has no significant web presence on industry-related sites.

We recommend a much better alternative peptide vendor to meet research material needs.

Top Peptides Review | Verdict

To conclude, Top Peptides is not the best source for the online purchase of research chemicals and peptides. Though it does carry a notable range of popular peptides, SARMs, and nootropics, the absence of any testing or quality guarantees does not inspire confidence.

While Top Peptides has garnered some favorable reviews concerning product quality, pricing, sales, and customer service, there are numerous reports of low product quality and poor handling of client concerns. The payment and shipping options are also lacking as evidenced on the company website.

Researchers are much better off with a reputable online source.
