Peptides Are Not Set It and Forget It
One of the most common misconceptions about peptide therapy is that it works like a supplement — take it daily, see results, continue indefinitely. The reality is more dynamic, and understanding how these therapies actually workchanges what you should look for in a provider.
Your Starting Dose Is Not Your Permanent Dose
Peptides are titrated. The dose you begin with is not necessarily the dose you stay on. As your body responds, the protocol adjusts — sometimes up, sometimes down — depending on what you’re experiencing and what your clinical team is tracking. That ongoing adjustment is a feature of good clinical care, not a sign that something isn’t working. At Ivim, real-time titration is built into how we practice. Our providers don’t set a protocol and walk away. Through unlimited consultations, we stay close to how your body is responding and make changes as needed, because what’s right at week two is often different from what’s right at month four.
Many Peptides Are Also Cycled — and the Reason Matters
Many peptides are also cycled, and understanding why makes a real difference in how you approach them. Dr. Duncan explains: “A lot of peptides are cycled in a way that allows your body to have the chance to start naturally producing its own peptide again. By stopping them periodically, for some peptides, that can actually be really beneficial.” The break gives the body an opportunity to bolster its own production rather than becoming reliant on an external source — a fundamentally different model from most treatments people are familiar with. In practice, a cycle typically runs two to four weeks on a given peptide, followed by a rest period of similar length. Some peptides don’t require cycling; others are sensitive to it. The specific approach depends on the compound, how your body is responding, and what your clinical team sees in follow-up.
Why Ongoing Check-ins Are Part of the Protocol, Not a Formality
Regular contact with your provider matters as much as the peptide itself. Dr. Duncan recommends monthly touchpoints as a general framework, with more frequent contact during active cycling periods. “What works for somebody on social media may not work for you,” she says. “We can customize the dose, the regimen, the interval, how often you’re taking them.” That customization is the difference between a protocol that works and one that doesn’t. If you’re evaluating providers for peptide therapy, ask specifically how they handle titration and cycling — a provider who sets a protocol and doesn’t revisit it isn’t really managing it. Peptide therapy done well is a living protocol, and the clinical relationship is what keeps it calibrated.
Frequently Asked Questions
How often will I need to check in with my provider?
Monthly check-ins are appropriate for most peptide protocols. If you’re in an active cycling period, your provider may want to connect during the transition to assess how you’re responding before the next cycle begins. At Ivim, unlimited provider consultations mean that contact isn’t limited to a schedule — if something comes up between check-ins, you can reach your clinical team.
What does a cycle mean in peptide therapy?
A cycle refers to a defined period of taking a peptide followed by a deliberate break. A typical cycle runs two to four weeks, followed by a rest period of similar length. The purpose is to give the body a chance to maintain or bolster its own natural production of the relevant signaling molecule, rather than becoming dependent on an external source. Not all peptides require cycling — your provider will specify what’s appropriate for the compound you’re on.
What happens if I just stop taking a peptide?
It depends on the peptide and how long you’ve been on it. For most, stopping means the effects gradually diminish as the compound clears your system. For peptides that were supporting natural production, stopping may actually be part of the protocol rather than an interruption of it. If you’re considering stopping for any reason, that’s a conversation to have with your provider.
How do I know if my dose needs to be adjusted?
Signs that a dose may need adjusting include not seeing expected progress after an adequate trial period, experiencing side effects that suggest the dose is too high, or changes in your health picture that shift the risk-benefit calculation. Your provider should be tracking this with you over time — it’s one of the core functions of ongoing clinical oversight, and at Ivim it’s built into every protocol.
