Medically reviewed by the clinical team at OC Weight Loss and Medspa. Last updated May 18, 2026.
In one paragraph: The Irvine professionals we see for peptide therapy are usually optimizing three things at once — energy at the end of a long workday, sleep that keeps slipping, and recovery from training that does not bounce back the way it did at 30. The three peptide options with the strongest evidence and the cleanest safety profile are NAD+ (cellular energy), Ipamorelin or Sermorelin (sleep and lean-tissue support), and our GLOW blend for skin and connective-tissue support. We do not offer BPC-157 or TB-500 — both are gray-market without human RCTs. Our office is 15 minutes south of Irvine on the 5.
Why Irvine professionals look at peptides
The conversation we have with Irvine patients in their late 30s and 40s tends to start the same way: “I am doing everything right and I do not feel right.” Sleep is fragmented despite a reasonable bedtime. Energy crashes mid-afternoon. Training takes more recovery than it used to. Cognitive performance feels like it has narrowed.
For some of those patients the answer is hormonal — testosterone in men, hormone shifts in perimenopausal women, undertreated thyroid. For others it is metabolic — insulin sensitivity slipping, visceral adipose creeping in. Peptides are not a replacement for those workups. They are a layered tool when the foundation is solid and the patient wants more from sleep, recovery, and energy.

What we offer (and what we do not)
For the educational background on BPC-157 specifically, see our BPC-157 educational guide.
The three protocols Irvine patients book most
1. NAD+ for energy and cognitive clarity
NAD+ is a coenzyme central to mitochondrial energy production and to sirtuin-mediated DNA repair. Levels fall with age and with chronic metabolic or sleep stress. Replenishing NAD+ is delivered either as an IV infusion (60–120 minutes, faster onset) or as subcutaneous injections (slower, more convenient). Tech-sector patients respond well to the cognitive-clarity signal in the first 2–4 sessions. See NAD injection benefits and the locally focused NAD therapy in Irvine.
2. Ipamorelin or Sermorelin for sleep and recovery
Ipamorelin is a selective growth-hormone-releasing peptide that prompts the pituitary to release endogenous GH in pulses, particularly during early sleep. The most consistent patient-reported effect is deeper slow-wave sleep within 2–4 weeks. Sermorelin is a GHRH analog that pushes the same axis from a different angle. For the head-to-head, see Ipamorelin vs Sermorelin.
3. GLOW blend for skin, connective tissue, and anti-aging
Our GLOW blend pairs growth-factor-supporting peptides with NAD+ precursors for patients whose goals are skin quality, hair quality, and a general anti-aging axis rather than pure performance. It is not a substitute for in-office aesthetic procedures — it complements them.

What does it cost?
- NAD+ IV: $300–$600 per session; protocols typically run 4–10 sessions
- NAD+ subcutaneous: $200–$350/month
- Ipamorelin (± CJC-1295): $300–$500/month
- Sermorelin: $250–$450/month
- GLOW blend: priced per protocol — discussed in your consult
What the evidence shows
For the GH-secretagogue family there are several human studies supporting modest sleep and body-composition effects when used under medical supervision. Tesamorelin (a long-acting GHRH analog) has FDA approval for HIV-associated lipodystrophy on the strength of its visceral-fat and IGF-1 data (Falutz et al., NEJM 2007). For NAD+ replenishment, early human work shows improved mitochondrial markers with oral precursors (Martens et al., Nat Commun 2018); the IV NAD+ literature is smaller.
How a first visit runs
- 20-minute clinician consult covering goals, symptoms, training and sleep history, and medications
- Lab order: CBC, CMP, IGF-1, fasting glucose/HbA1c, lipids, total + free testosterone (men), thyroid panel
- Treatment plan proposal once labs return — peptide selection, dose, route, follow-up schedule
- 90-day reassessment with repeat relevant labs and a structured outcome conversation
After-work scheduling for Irvine professionals
Late Friday and Saturday morning are the most-booked slots for Irvine patients. NAD+ IV sessions need to be planned (60–120 minutes); subcutaneous protocols, Ipamorelin, and Sermorelin are short visits or self-injected at home after the first training visit.
FAQ for Irvine peptide patients
Are these peptides FDA approved?
Sermorelin and Tesamorelin have FDA-approval history in specific indications. Ipamorelin, CJC-1295, and our peptide blends are compounded by licensed U.S. pharmacies and prescribed off-label under physician supervision. NAD+ is a coenzyme administered as a nutritional therapy.
Why do you not offer BPC-157?
The FDA placed BPC-157 on the 503A Category 2 list in 2023, which means it cannot be lawfully compounded for office or patient use. There are also no published human randomized controlled trials.
How fast will I feel a difference?
NAD+ effects on energy and clarity typically show up in the first 2–4 sessions. Ipamorelin and Sermorelin show a sleep effect within 2–4 weeks and body-composition shifts over 3–6 months.
Can I self-inject at home?
Yes for subcutaneous protocols once you have been trained at the first visit. NAD+ IV remains in office. NAD+ subQ can be done at home after a training visit.
Will peptides interact with GLP-1 medications?
No clinically meaningful interaction. NAD+ is commonly added during GLP-1 therapy to support energy when caloric intake drops. Ipamorelin or Sermorelin can layer with GLP-1 when lean-mass preservation is a goal.
Do I need to keep taking peptides forever?
No. Most protocols are time-bounded — 3–6 months of active dosing, then a reassessment to decide on a maintenance schedule or a break. We do not promote indefinite escalation.
How is sourcing handled?
All peptides are compounded by licensed U.S. 503A or 503B pharmacies with traceable lot numbers. We do not use “research peptides” from unregulated suppliers, and we discourage patients from doing so on their own.
Talk to a clinician at OC Weight Loss and Medspa
If you are an Irvine professional thinking about peptide therapy and you want a clinician-led consult rather than a counter pitch, our office is 15 minutes south on the 5 with after-work and Saturday hours. We run physician-supervised peptide therapy for NAD+, Ipamorelin, Sermorelin, CJC-1295, and our GLOW blend. For the same protocols closer to home, see peptide therapy in Mission Viejo.
