Common questions
Is peptide therapy safe?
Yes, peptides are generally well-tolerated and safe when prescribed and administered under medical supervision. Our program uses clinically-tested, pharmaceutical-grade peptides and protocols tailored to your specific health needs and goals.
Is peptide therapy covered by insurance?
Currently, peptide therapy is not covered by most insurance plans, and our program is out of pocket only.
How much do peptides cost?
Peptide therapy cost may vary by peptide type and dosage.
What is a peptide protocol?
A peptide protocol is a structured, personalized dosing plan for using specific peptides over a designated period. This plan includes precise information on the dose, frequency, and duration for each peptide, tailored to your unique health goals.
Are all peptides injectable?
While many peptides are self-administered injections, some peptides are available as nasal sprays and oral tablets. Our clinical team will discuss administration mechanisms during your consultation.
How long does it take to ship an order?
We offer next-day shipping to ensure your peptides arrive promptly. Orders can be shipped Monday through Thursday. (Tri-state area: $40, Out of state: $60)
Are there any peptides that help with sleep?
Several peptides have been shown to reduce sleep interruptions and promote better sleep wake cycles (circadian rhythm). During your longevity consultation, a member of our clinical team will review your sleep concerns and goals, before exploring some peptide for sleep options, including a Pinealon spray.
Can peptides help with anti-aging?
Various studies have shown that peptides like GLP-1 peptides for weight loss and anti-inflammation peptides may help promote anti-aging benefits. For example, the GLP-1 semaglutide has been shown to reduce up to 15 % body weight among some patients. A reduction in body weight may help reverse pre-diabetic risk and cardiovascular risks.
Who is a good candidate for peptide therapy?
Your peptide therapy candidacy is determined after a clinician reviews your health history and goals during your longevity consultation. Typically, a peptide candidate is an adult who is relatively healthy, but may be experience ongoing wellness concerns, like inflammation, fatigue, weight gain, insomnia, low libido, and difficulty focusing.
