Is Proven Peptides Closed?

Yes, Proven Peptides ceased operations permanently in 2021.

The online SARMs retailer was based in North Carolina and had been operating since 2015, selling liquid SARMs of questionable quality with mixed reviews. The vendor made claims to legitimacy, citing third-party test results, and gained a substantial client base during its tenure. However, the company shut down last year due to the founder’s indictment by the US government.

Read on to learn why this occurred and how to pick the best alternative online source for quality research chemicals and peptides.

Why is Proven Peptides Ceasing Operations?

Owner charged with fraud

Proven Peptides ceased operations with the federal indictment of Josh Fulton in 2021 on a charge of conspiring to defraud the United States [1]. The charges pertained to Fulton’s dealings related to Proven Peptides, as well as several other substance retail companies he owned, such as Peak Nootropics, Coastline Kratom, and Absorb Health [2].

Nature of The Case

Through his businesses, Fulton made false claims about the health effects of the substances that he marketed and sold. Further, production took place in an unregulated facility that he had neglected to register with the Secretary of Health and Human Services, as ordered by federal law [1]. In advertising the direct health effects of the products, he implied that they were fit for human consumption, deceiving both customers and the government to potentially dangerous effects.

Broader Implications of This Case for Research Chemical Retail

The circumstances of this vendor’s closure speak to larger issues in the online research chemical industry. These are:

  • Lack of accountability
  • Few regulatory practices are in place
  • Potential dangers of the misuse of low-quality products

Even before the indictment, Proven Peptides had come under fire from customers who cited poor quality, damaging effects through misuse, the fabrication of purity reports, and bad business practices. However, clients continued to patronize the SARM distributor despite alarming reviews citing grave health effects through improper consumption, as well as fraud [3, 4].

Many other businesses in the burgeoning industry take advantage of the relative lack of regulations, treading the line between unethical measures and criminality.

Importance of a Trusted Source

For these reasons, researchers should identify and purchase exclusively from legitimate online sources. Luckily, we have identified the most reputable online research peptide and chemical retailer that is guaranteed to meet study needs.

Who is Limitless Life?

Limitless Life is an American vendor of research chemicals and peptides. It is currently the standard-bearer of quality and innovation in the industry, making it the leading source for experts in the scientific community throughout the world.

Let’s dive into the main features of this company:

What are Peptides?

Peptides are chains of amino acids that play many vital roles in biological processes. Current research supports the potential of synthetic peptides in a range of therapeutic contexts, from combating symptoms of cardiovascular disease to slowing the effects of aging. This young field is full of emerging innovations.

Why do I need to Buy From a Reputable Source?

Research peptides are primed to play key roles in future pharmacological advances. Unfortunately, there is a relative lack of regulation in the burgeoning field, and online retail practices are rife with poor-quality products and questionable business practices. Substandard purity levels can significantly diminish both the efficacy and safety of peptides and research chemicals in therapeutic contexts.

What Makes Limitless Life the Best in the Field?

Verified product quality: Limitless Life is the best name in research peptide quality due to its stringent production methods and rigorous third-party lab testing, ensuring minimum purity levels of 99% in all available products. Domestic manufacturing within the USA adheres to the country’s quality measures, which are the most comprehensive in the world.

The vendor tests all products using the high-performance liquid chromatography and mass spectrometry (HPLC-MS) technique. This ensures with precise accuracy the sequential fingerprints and utmost purity levels of all peptides available for purchase. Valid certificates of analysis are readily available to the public via the state-of-the-art website.

Superior business practices and client experience: Limitless Life is a leading name not just for its great products, but for its outstanding commitment to client satisfaction. The vendor has an easily accessible customer service team on hand for quick responses to client queries. Check-out is easy, quick, and secure on the educational website, and many forms of payment are available with the protection of cutting-edge SSL encryption technology.

The retailer offers low shipping rates to countries around the world, and even waves shipping costs on domestic orders over $200. All deliveries are trackable and performed through trusted shipping services. Plus, price breaks are available on bulk purchases.

What About SARMs?

Limitless Life is a specialized company and does not produce selective androgen receptor modulators (SARMs). However, this does not disqualify the vendor as the top alternative to SARMs retailers, especially low-quality names such as Proven Peptides.

Though peptides and SARMs are chemically distinct, their therapeutic applications may overlap. In fact, peptides may have greater therapeutic potential and fewer negative side effects than SARMs in certain contexts [5, 6].

As a distinct class of chemicals from peptides, SARMs are produced via different methods that require specialization to be effective and safe in therapeutic contexts. However, as we have seen in the case of Proven Peptides, the SARMs arena is rife with poor practices due to a relative lack of regulation. So, the best option is a trusted source like Limitless Life that is qualified to produce compounds of proven quality [6, 7].

Is Limitless Life Legit?

Yes, Limitless Life is a legitimate source for research material needs. Why?

Proven Product Purity

Limitless Life is a truly reputable name. Check out these credentials:

  • Available products are sourced in the USA and in exclusive partnership with cGMP manufacturers. This guarantees product quality and enables Limitless Life to maintain the best prices.
  • Peptide purity is established via stringent quality control procedures throughout all phases of production. These include testing per the pharmacological standard of high-performance liquid chromatography and mass spectrometry (HPLC-MS).

Where to Buy Peptides Online? | 2024 Edition

Limitless Life has an impressive catalog of research peptides. Here are the top two peptides available from the vendor.

Limitless Life BPC-157

BPC-157 is synthetically derived from BPC (Body Protection Compound), an angiogenic that is produced in the mammalian GI tract. The compound heals lesions of the gastrointestinal lining, fortifying and protecting it to enable proper digestive functioning [8]. It is currently under review for its potential therapeutic benefits. It may be safe and effective as a neuroprotectant, tissue growth stimulator, and healing agent [9, 10, 11, 12].

Limitless Life TB-500

TB-500 is a manufactured form of thymosin-beta 4, an angiogenic compound that serves to upregulate actin and promotes cellular regeneration [13]. Ongoing clinical studies suggest the peptide’s potential therapeutic uses in combating symptoms of cardiovascular disease, improving the healing of injuries, and addressing the symptoms of inflammatory diseases.

It shows additional promise as an anti-aging agent and maintains a favorable safety rating for use in appropriate settings [14, 15].

Limitless Life Semaglutide

Semaglutide is a synthetic analog of glucagon-like peptide-1 (GLP-1) that is used to control blood sugar and stimulate weight loss. With a mechanism that increases insulin while reducing glucagon production in a glucose-dependent manner, semaglutide is known to reduce fasting and postprandial blood glucose levels.

It has undergone extensive clinical testing before gaining the FDA’s approval as both an antidiabetic treatment and weight loss agent in both diabetics and nondiabetics [16, 17, 18].

Limitless Life also carries research-grade tirzepatide, the longevity research peptides GHK-Cu and epithalon, and potent GH secretagogues like ipamorelin and CJC-1295.

Proven Peptides Review | Overall

In conclusion, Proven Peptides was not a reputable online research chemical source. The company’s closure due to the owner’s federal indictment supports our evaluation.

Fortunately, there is a far superior alternative for the online purchase of research materials. Look no further than Limitless Life, the industry leader in quality, integrity, and innovation.
