Medically Managed Peptides

Historically a realm of health optimization reserved for body builders and biohackers, peptide therapy has evolved from DIY, internet-options to a well-researched, safe, and effective way to address a multitude of diseases and health goals. BLI began offering Medically Managed Peptide services in 2017 to provide our clients with a way to take advantage of the benefits of peptides in a way that is strategic and safe, guided by our providers’ unique expertise in peptide therapies.

What Is A Peptide?

Peptides are often thought of as “signaling agents” that can boss cells around by queuing certain actions or behaviors inside the body. A peptide is a short-chain of amino acids, which, together with other peptides, forms a protein. Because they work at the cellular level, peptides have the potential to fundamentally shift the paradigm of aging and disease. Peptides have been shown to impact everything from arthritis, neurodegenerative disease, diabetes, autoimmune dysfunction and nearly every ailment impacting the modern population.

What Are Peptides Used For?

Peptides are useful as a form of treatment for many conditions. Some peptides can encourage the production of growth hormone in the body, helping manage age-related issues and chronic inflammatory diseases. Some are impactful in the treatment of obesity or weight management, as they encourage the death of excess fat cells. One type of peptide is even known to encourage the production of melanin, decreasing the chances of skin cancer. Others can be therapeutic for an array of sexual dysfunctions.

Are Peptides Safe?

Though peptides are often thought of as a cutting-edge field of medicine,they have been well researched to be safe and effective (many peptides are even found in FDA-approved medications or as pharmaceutical options in other parts of the world). At BLI, we source our peptides from vetted compounding pharmacies all around the country. Unlike the peptides you can buy off the internet, every peptide we provide our clients is prescribed and filled by one of these established pharmacies.

"What are peptides used for?"

Peptides can be a useful treatment for many conditions. These amino acids work in various ways, impacting functions like hormone production, cellular senescence, and inflammation.

Uses include weight management, age-related issue management, sexual dysfunction therapy, and there is even promising evidence of peptides decreasing the chances of certain diseases like cancer.

Boulder Longevity Institute (BLI) sees peptides as having the potential to fundamentally shift the paradigm of aging and disease. Arthritis, neurodegenerative disease, diabetes, and many other modern ailments can be impacted by peptide therapies. On the optimization side, peptides can be used to build muscle, cut fat, increase cognition and enhance performance. Working with one of BLI’s Certified Peptide Specialists (CPS), clients receive tailored guidance and access to novel peptide therapies aimed at addressing specific health goals or concerns.

Simply, peptides are another useful tool the experts at BLI use to optimize your overall health and longevity.

"How much does peptide therapy cost?"

Answering the questions, “How much do peptides cost?” is a lot like answering the question, “How much do supplements cost?”. The answer is very unique and individualized to you. Much like someone might spend $50 per month on just one supplement or upwards of hundreds of dollars monthly for a more involved regiment; the cost of peptide therapy depends on many factors including your personal goals, priorities, health needs and budget.

The cost of peptide therapy is highly dependent on dosing and treatment goals. A basic, one-peptide protocol may be anywhere from $100 to $500 per month. Most clients at Boulder Longevity Institute are on multiple peptide therapies at a given time. For more involved and multi-peptide protocols, a treatment plan may be upwards of $1,000 monthly.

Working with a Peptide Certified individual like those at the Boulder Longevity Institute for medically managed peptides allows you to receive guidance on how to prioritize and manage the peptides you need. If you are looking to do a targeted session to address a key issue, then bumping up the budget for a few weeks may be warranted. If cost is becoming a concern, we can work with you to reduce costs and prioritize what provides the highest impact. Programs like BLI’s Human Optimization Program (HOP+) ensure safe, appropriate peptide protocols suited to fit your specific needs.

Is it less expensive to DIY peptides? Possibly. However, purchasing “research-only” peptides online comes with inherent risks and ambiguity. Though there are quality suppliers out there, online purchases often bring confusion around dosing and administration, along with ambiguity on sourcing and purity. A scatter shot, self-guided approach may lead you to miss out on the benefits of a guided, medically managed protocol.

In general, zeroing in on a dollar value, or even a wider cost range, is virtually impossible due to the multitude of variables at play; rather, it may be more important to note the value of peptide therapy and the specific goals you have for your health. Considering costs is unavoidable. However, we urge you to look beyond simple dollars and cents toward the long term benefits that will help you enjoy a longer, healthier lifespan. At BLI, we believe that investing in your health is one of the best investments you will make.

"What are peptide injections?"

Peptides are small chains of amino acids considered the building blocks of proteins. Peptides are involved in or regulate a multitude of functions. We now know that peptides offer diverse therapeutic applications.

Peptide therapies are often delivered in the form of a subcutaneous injection. Subcutaneous injections are typically self-administered, painless and simple. A very small insulin-size needle is used to draw up a peptide mixture from a vial and then injected into the skin.

Peptide injections allow for quick, effective circulation throughout the body. In some cases, the injected peptides can be targeted at a specific area, making them potentially more effective. For instance, studies have shown that injecting the peptide Thymosin Beta-4 into an injury site can provide significant pain relief.

Many people associate peptide injections with big, musclebound individuals. This likely comes from the popularity of growth hormone secretagogues (GHS), which stimulate human growth hormone (HGH) production.

While GHS is seen as a safer alternative to simply injecting HGH, there are far more uses than simply to improve physical appearance and musculature.

The benefits of peptide injections and peptide therapies are still being discovered. This is unsurprising, given there are more than 7,000 peptides produced naturally by our bodies. Peptide therapies are game changing for our overall health and longevity.

Peptide injections are available via various sources, however, we always recommend consulting with professional Peptide Certified individuals like those at the Boulder Longevity Institute. This ensures the curation of peptides that are most effective, safe, and appropriate for you.

"Is it safe to use peptides?"

The cutting edge nature of peptides and the science surrounding them leads many to ask if peptides are safe to put into their bodies. Peptides have been thoroughly researched for their benefits but also for their safety.

The FDA has approved medications containing peptides and you can find them being used pharmaceutically in many other parts of the world. Most peptides have very few risks and minimal, if any, side effects. However, it is important to understand where your peptides are coming from.

The Boulder Longevity Institute (BLI) sources its peptides from vetted compounding pharmacies. This allows BLI to be confident in the products being provided to clients. It is not recommended to source peptides from the internet both for safety and efficacy. Peptides purchased online are sold as “research-only” peptides to allow for online resale. Much like the FDA doesn’t regulate supplements, buying “off the shelf” peptides can lead to unexpected outcomes.

For healthy people, peptides generally do not cause side effects. This is because peptides are already present in our bodies and in foods we eat. However, it is valuable to seek out professional management of any peptide therapies.

Effective peptide therapy requires an expert-level understanding of how peptides work in the body, what peptides are beneficial for specific needs, and the appropriate peptide protocols.

Getting an assessment from a Peptide Certified expert is the safest, most effective way to harness the power of peptides for human optimization.

"How long do peptides take to work?"

We know peptides are powerful little amino acid chains that tell the body what to do. The time it takes for them to work can vary, of course.

There are many variables that impact how long it might take for you to notice the impacts of beneficial peptide therapy. In many cases, benefits begin rather quickly culminating in optimal performance three to six months after starting peptide therapy. Some peptides may exhibit impact within days or weeks.

It is important to note that when considering peptide therapy protocols, there is no one size fits all solution. Working with one of BLI’s Certified Peptide Specialist, you can adapt and evolve your peptide protocol to meet your needs and goals at any given time.

Like most things related to your health, it can be difficult to say how long it may take to optimize your health. Some peptides will have immediate effects, while others work slowly and gradually over time. Taking the appropriate steps of contacting a Peptide Certified provider will put you on the path to a stronger, healthier aging process.
