🚨 Alert: Paradigm Peptides Vendor Shut Down, the investigation

The Shutdown of Paradigm Peptides

The banner on the website now, see for yourself

During the last week of March 2024 the unexpected shutdown of Paradigm Peptides caught the attention of many, marked initially by a seemingly innocuous “site undergoing maintenance” message on their website. This default WordPress maintenance notification raised eyebrows, prompting further investigation. Subsequent checks on the site revealed no progress, and attempts to contact the company through email went unanswered. It wasn’t long before the website’s message was updated to a more definitive “site is closed,” accompanied by a promise that all customers would receive refunds. This abrupt closure has left many in the community seeking answers and alternatives.

Investigating the Closure

The question of why Paradigm Peptides shut down, especially when similar companies appear to be operating without issue, is complex. A graph of their website traffic might have shown a thriving business, dealing in significant volumes of SARMs and other research chemicals. Yet, the practices that set Paradigm Peptides apart may also have been their downfall.

Unlike other research chemical suppliers that carefully market their products strictly for research purposes, Paradigm Peptides ventured into risky territory. Their extensive blog, filled with articles on usage, dosage, and detailed peptide application instructions, blurred the lines between research and practical use. This approach, while valuable for a segment of their audience, attracted scrutiny.

Regulatory Challenges

The letter from FDA

The link between their marketing practices and regulatory attention is not speculative. Paradigm Peptides previously received a warning letter from the FDA, specifically addressing their marketing strategies and the implied use of their products for Coronavirus.


Such letters are a clear indication of the FDA’s stance on the sale and promotion of SARMs and peptides for human use.

The Risks of Overexposure

Paradigm Peptides’ strategy of providing in-depth content on peptide applications may have been a double-edged sword, offering both value to their customers and drawing unwanted regulatory attention. In the world of research chemicals, maintaining a balance between educating consumers and avoiding claims of promoting human consumption is crucial. Paradigm Peptides, it seems, may have leaned too far into the former, leading to their current predicament.

They were getting a significant amount of traffic to the blog due to organic search, see an estimation below.

Orangic traffic to, notice the drop off at the end.

While details of the exact cause of their shutdown remain unclear, parallels can be drawn to other high-profile cases within the industry. Companies facing similar issues often endure raids, product confiscations, and legal challenges, although severe penalties are rare. The fate of Paradigm Peptides serves as a cautionary tale for the industry, underscoring the importance of navigating the fine line between providing valuable information and adhering to regulatory guidelines.

Moving Forward

As subscribers and advocates of research in this field, the closure of Paradigm Peptides is undoubtedly a setback. However, it also presents an opportunity to explore alternative sources for research chemicals. There are several reputable companies currently operating, and with the anticipated launch of new suppliers, the community remains vibrant and resilient. As we navigate these changes, our commitment to safe, informed, and responsible research remains steadfast.

While the sudden disappearance of Paradigm Peptides from the market leaves many questions unanswered, it also reinforces the need for vigilance and adherence to regulatory expectations within the research chemical community. As we look to the future, the lessons learned from this incident will undoubtedly shape the industry’s evolution, ensuring that exploration and innovation can continue within the bounds of safety and legality.

Our Experience and Experiment (When they were open)

I am currently healing from a back injury induced by deadlifting. I have a bulged disc between my L4 and L5 vertebrae and it’s been over six months.

I already did a 30-day BPC-157 cycle and think it helped a lot, injecting near the lower back in the fat on the sides of my spine. This was prescription grade and was ordered by my provider at Marek Health.

Unboxing Paradigm Peptides

Fun fact, prescription-grade BPC-157 costs $350 for ONE vial of 15mg. Paradigm charges $48 for 5mg or $144 for 15mg. A huge price difference, but is it as good?

I decided to do another cycle but this time of TB-500, I chose Paradigm Peptides for the brand. They tout their quality and I want to see what TB would do vs BPC.

Who Are Paradigm Peptides?

The inquisitive minds behind Paradigm peptides sensed a strong gap between the market demand for peptides and the online stores/vendors offering premium and authentic peptides. Thus, Paradigm Peptides was founded in 2014 with a strong intent of revolutionizing the peptide industry.

Paradigm Peptides is a fully functional company US-based company. In the initial business days, Paradigm Peptides partnered with many old horses cum local US-based peptide manufacturers to source their premium peptides.

As the company grew, Paradigm Peptides set up their laboratories based out of Tennessee and expanded their logistics, such as manufacturing plants and distribution channels in the midwest.

The highly experienced team running the Paradigm peptides knows the peptides, SARMs, and the potent nootropic products inside out. With their prime focus placed on the research chemicals and their laboratory testing, Paradigm Peptides claim to offer 98 to 99% purity and authenticity in the company’s products.

How Do Paradigm Peptides Work?

As a client-centered brand, Paradigm Peptides spend a great deal of time on specific requirements, research chemicals, and then manufacture high-quality peptides, SARMs supplements, effective nootropics, and associated lab supplies.

They sell their products in tablet form, capsule form, injectable versions, etc.

As one of the leading retailers in the peptide business industry, they believe in meeting top-quality standards. To achieve that, they usually collaborate with independent researchers as well as mega research/clinical institutions to stay up-to-date with modern research chemicals. This also ensures that all products are lab-tested and purity is guaranteed.

Not only this, they are open to providing resources, such as research papers, details of clinical trials, and other specific guidelines that you may need.

Perhaps the unique selling point or USP of Paradigm peptides is the fact that they are the first and only brand to eliminate Trifluoroacetic acid or TFA from their manufactured peptides.

For those of you who don’t know what TFA is, it is one of the compounds known to cause tissue damage. It is important to note that most peptide manufacturers add that into the peptides.

One of the other minor yet significant measures adopted by Paradigm peptides is vacuum sealing the vials. This ensures that no moisture meets with their lyophilized powder.

What’s amazing is the fact that they are also open to offering you custom-based products. For example, if any peptide is not available on the Paradigm peptides website, what you can do is just request them and send them specific details. Paradigm peptides will manufacture your peptide by meeting the highest quality standards. Perhaps you will also get test reports so that you know what you are getting!

They also run a blog that will not only make your shopping experience easier but also keep you posted with modern and contemporary knowledge/research on peptides and the associated information, such as storage methods, reconstitution ways, cycling techniques, etc.


If you are a bodybuilder, and you have just completed one cycle of anabolic steroids, I am sure you would know what Post cycle therapy or PCT is.

One of the highly used therapeutic compounds for PCT is Clomiphene citrate or Clomid. It helps the bodybuilder to come back on the natural track once the anabolic steroid cycle ends. It kinds of acts as a buffer for the body.

The normal duration of PCT is around 4 weeks, and the recommended dosage is 20mg to 50mg.

Other PCT compounds offered by Paradigm peptides are Tamoxifen Citrate and Rebirth.
