INTRODUCING CORE-X PRIME
A More Complete Approach to Optimization
Core-X Prime takes a broader view of wellness by looking at the interconnected systems that influence how you feel, recover, perform, and age.
Rather than treating one concern in isolation, your provider considers how metabolic health, energy, recovery, hormones, cognition, body composition, sexual wellness, and healthy aging affect one another.

Yes. Patients from across Southern Colorado are welcome, including Pueblo West, Colorado City, Rye, Beulah, Cañon City, Florence, Walsenburg, Trinidad, La Junta, and Rocky Ford. Many patients can get started with intake paperwork Dr. Key reviews, so a long drive is not always necessary. Call (719) 544-4405 and we will walk you through it.
Peptides are short chains of amino acids that act as signaling molecules in the body. Peptide therapy refers to the medical use of specific peptides as part of a treatment plan. Whether any peptide therapy is appropriate depends on an individual medical evaluation, and not every patient will be a candidate.
That determination is made with a qualified provider after reviewing your health history, current health, goals, and any relevant testing. General information, including the information on this website, can't tell you which therapy is right for you.
Not always. Many patients get started with intake paperwork that Dr. Key reviews, which can be completed from home. Some therapies do call for an in-person visit or lab work first. Call (719) 544-4405 and we’ll tell you which applies to what you’re interested in.
Yes. Recommendations are based on your individual history, goals, and medical needs rather than a standard package. Two people with similar goals may receive very different recommendations, and some may be advised that a therapy isn't appropriate.
It begins with a conversation about your goals and health history, in the office or through intake paperwork, followed by a review from Dr. Key. If appropriate, you'll receive a personalized plan. Your progress is then monitored, and recommendations may be adjusted over time.
Review frequency depends on your plan and your provider's recommendations. Follow-up is built into the process so your plan can be adjusted as your needs, goals, and progress change.
No. Peptide therapy isn't right for everyone. Certain health conditions, medications, pregnancy, and other factors may make some therapies inappropriate. Your provider will discuss potential benefits, risks, and alternatives with you during your evaluation.
