Who is Paradigm Peptides?

Paradigm Peptides is a USA-based company that manufactures research chemicals and peptides for online sale to qualified researchers. Founded in 2014, the company partners with primarily domestic manufacturers to produce high-quality SARMs, nootropics, and various peptides.

The vendor’s core philosophies include constant research and innovation, as well as a commitment to quality assurance and customer service. Let’s dive into these features:

  • High-grade products at moderate prices: Paradigm Peptides aims to implement quality control measures at all manufacturing phases, from production to packaging and shipping. All available products are advertised as at least 98% pure, and free of TFA, a toxic additive found in many synthetic peptides on the market. Small-batch products are vacuum sealed to prevent degradation.
  • Good customer service: The company website is a decent resource to learn about all available products with some articles on relevant research. A customer service team is available via email or phone as part of Paradigm Peptides’ client-centered approach.
  • Payment options and international shipping: Paradigm Peptides accepts several payment options, and orders are shipped throughout the world. Researchers can select expedited shipping options, albeit with added charges.

With a wide selection of product types, claims of quality assurance, and payment options at check-out, Paradigm Peptides is a reliable online source for SARMs, nootropics, and peptides. All products are available in powder or capsule form.

Peptides Sold by Paradigm Peptides

Here are the top three peptides available from Paradigm Peptides:

Paradigm Peptides BPC-157

BPC-157 is a pentadecapeptide that derives from Body Protection Compound, which is found in the GI tract. The angiogenic compound heals and protects the lining of the gastrointestinal tract and is vital to GI function [1]. It has great therapeutic potential such as stimulating muscle, tendon, and skeletal growth, as well as speeding injury healing and protecting the nervous system [2, 3, 4]. Currently, it is considered safe when handled by qualified professionals [5].

Paradigm Peptides TB-500

TB-500 is a synthetic form of thymosin-beta 4, which upregulates actin and acts as an angiogenic to speed up cell regeneration and healing [6]. Clinical studies indicate the peptide’s therapeutic potential in combating cardiovascular disease, improving injury recovery, and treating inflammation. It also has anti-aging effects and a high safety profile to date [7, 8].

Paradigm Peptides Melanotan 2

Melanotan 2 (MT-2) is a synthetic analog of alpha-melanocyte-stimulating hormone. When administered, MT-2 acts upon the melanocortin receptors to darken the skin, counter male erectile dysfunction, increase sexual arousal, reduce appetite, and combat addictive or obsessive behavioral patterns. It may also boost lean muscle mass and has a good safety record [9, 10, 11].

Paradigm Peptides also carries these notable research peptides:

The company’s shipping practices are as follows:

  • Orders ship out within 2 business days of payment by credit card or cryptocurrency, and within 7 to 10 business days of payment by e-check
  • The website advertises a flat shipping rate of $7.90 that covers USPS priority shipping to domestic and international locations. However, it is stated that this is subject to variation.
  • Returns of damaged or incorrect shipments must be filed within 14 days of receipt.

In comparison to other leading vendors, Paradigm Peptides could offer more payment options, and their shipping policies are somewhat vague. Be advised that researchers may be subject to additional shipping and handling fees at checkout.


Benefits of Buying from Paradigm Peptides

Let’s explore the key features of Paradigm Peptides.

Quality Assurance Measures

Paradigm Peptides works to ensure that all its products are at least 98% pure. Peptide quality is established with pharmacological-grade quality control measures such as high-performance liquid chromatography and mass spectrometry analysis. SARMs are sold only in capsule form, as liquid SARM products risk degradation, and the vendor claims to adhere to the highest production standards. The company states that all chemicals are independently tested to guarantee purity levels, and extra measures are applied to remove toxic TFA from peptides.

Apart from bulk orders, products are shipped in vacuum-sealed containers.

Range of Product Classes

Paradigm Peptides has a diverse selection of research peptides and chemicals, from synergistic peptide blends to SARMs and nootropics. It also conveniently sells lab supplies such as sterile vials, syringes, and bacteriostatic water for all research needs.

Largely USA-based

Headquartered in Illinois, Paradigm Peptides partners with domestic manufacturers that are subject to rigid US production standards. This ensures top quality and lower price points. However, the company website indicates that some materials are sourced internationally.

Secure Payment and International Shipping

All client payment information is protected with encryption technology, and researchers can order from almost anywhere in the world for delivery.

Downsides of Buying from Paradigm Peptides

While Paradigm Peptides has some great features, the vendor does have some room for improvement. For example:

Lack of Specialization and Transparency

Some experts note that Paradigm Peptides may compromise quality for the wide variety of chemical types that it offers. For example, peptides and SARMS are only available in powders or capsules, in contrast to the multiple forms available from other leading vendors. Plus, bulk SARM orders are delivered in less secure tear-open plastic bags with little to no markings, and some experts find their SARM selection to be narrow.

The company site also presents a relative lack of information on quality assurance when it comes to SARM production practices, and they solicit third-party test results for batch reports. This could be a potential safety drawback [12].

Shipping Times and Rates are Unclear as Advertised

The website’s advertised shipping practices are somewhat contradictory. While a flat rate of $7.90 is put forth, it is further stated that this is subject to variation. Shipping rate hikes for expedited shipping are not presented clearly before checkout.

A Small Window of Return for Wrong Orders

Even in the case of company error, clients have only 14 days to file a grievance to be recompensated.

Relative Lack of Payment Options

In contrast to competitors, Paradigm Peptides accepts fewer third-party payment services. Further, some payment methods are subject to slower shipping times.

However, Paradigm Peptides maintains a loyal base due to its overall quality, stable track record, and commitment to client care.

Paradigm Peptides Reviews from Researchers

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

This satisfied client on Trustpilot gives the vendor top ratings:

“I have bought many products over the last 2 years from paradigm peptides and have always had a good experience. Their customer service is excellent even when I call with multiple questions, they always show patience and explain everything thoroughly. The products are great and always worked. That is more than I can say for similar products from one of their competitors.” [13]

Some clients give the vendor lower marks. A reviewer on a trusted SARM review website had this to say:

“Paradigm Peptides is a good vendor with lots of room for improvement, especially when you consider their lack of quality control. Regrettably, I won’t be able to include them to my list of recommended SARMs companies, since their lab reports are not accessible to the public.” [14]
