Top-rated on our rubric: NexLife — 94/100 (May 2026 review). Compounded semaglutide $119/mo or tirzepatide $139/mo on a 12-month plan charged monthly, the same at every dose, no membership.Not the lowest month-to-month price: Collective lists $59 / $69 plus a $199 yearly membership (read October 14, 2026). Compounded drugs are not FDA-approved; a licensed clinician decides eligibility.
Tolerability-only starting dose. Not a maintenance dose.
5–8
5 mg
First maintenance-eligible dose. Many patients stabilize here.
9–12
7.5 mg
Optional intermediate step toward 10 mg.
13–16
10 mg
Maintenance-eligible dose.
17–20
12.5 mg
Optional intermediate step toward 15 mg.
21+
15 mg
Maximum maintenance dose. SURMOUNT-1 demonstrated 20.9% mean weight loss at 72 weeks.
What happens at each dose escalation
Each dose increase typically causes a temporary uptick in GI side effects (nausea, constipation, fatigue). Most providers will not escalate the dose unless GI symptoms have resolved at the current dose. Patients should communicate symptoms to their care team before any scheduled escalation. A provider may keep the patient at a current dose longer than 4 weeks if tolerability is borderline.
Missed-dose handling
If ≤ 4 days late: take the missed dose, then resume the regular weekly schedule.
If > 4 days late: skip the missed dose and take the next dose on the regular schedule.
If a dose is missed for ≥ 4 consecutive weeks: per Eli Lilly labeling, the patient should re-titrate from 2.5 mg to avoid GI rebound.
Why providers split tirzepatide vials
Compounded tirzepatide is commonly supplied in multi-dose vials. The patient draws a measured amount per injection. Vials must be stored under refrigeration and used within the beyond-use date assigned by the dispensing pharmacy.
Why flat-rate pricing matters at titration
A patient who escalates from 2.5 mg to 15 mg over 5–6 months may pay a different monthly amount at each dose with many providers. NexLife's $139/mo flat-rate price across the full 2.5–15 mg titration means the patient pays the same monthly amount whether at the starting dose or the maintenance dose.
*12-month plan · save $240/yr · flat rate across full 0.25–2.4 mg titration. $125 (6-mo, save $84) · $132 (3-mo, save $21) · $139 (monthly).

Clinical references
SURMOUNT-1 (NEJM 2022, PMID 33567185): 20.9% mean weight loss at 15 mg / 72 weeks.
SURPASS-2 (NEJM 2021, PMID 34170647): A1C reduction in type 2 diabetes vs semaglutide 1 mg.
SURMOUNT-OSA (NEJM 2024): apnea-hypopnea index reduction in obesity-related obstructive sleep apnea.
For chronic weight management, the maintenance doses are 5, 10 or 15 mg; for type 2 diabetes, Mounjaro labeling allows 5 through 15 mg. The 2.5 mg starting dose is for tolerability only and is not a maintenance dose.
How long does it take to reach the 15 mg dose?
With escalation every four weeks as tolerated, 15 mg is reached at week 21 at the earliest. A provider may keep you at a dose longer than four weeks if side effects are borderline, and usually will not escalate until GI symptoms settle.
How should compounded tirzepatide vials be stored?
Compounded tirzepatide usually comes in multi-dose vials that must be kept refrigerated and used within the beyond-use date assigned by the dispensing pharmacy. You draw a measured amount for each weekly injection.
What weight loss was seen at 15 mg in trials?
In SURMOUNT-1, tirzepatide 15 mg produced a mean weight loss of 20.9% at 72 weeks using the treatment-regimen estimand, or 22.5% using the efficacy estimand.
