Learn exact protocols for missed doses: when to resume, whether to double dose, and how to adjust your schedule after gaps.
# How to Handle a Missed Peptide Dose: Rules by Compound Type Missing a peptide dose happens. The action you take depends on the compound, time elapsed, and your protocol. This guide provides clear rules for each major peptide category.
The golden rule: Never inject double dose to "make up" for a missed injection. This creates acute toxicity risk, overdose symptoms, and receptor saturation without additional benefit. Instead, resume at your normal dose on the next scheduled day.
If you remember within 5 days:
Inject your normal dose as soon as you remember (even if it's day 3-5 post-missed injection). Resume weekly injections from that new date.
Example: You missed your Monday semaglutide injection. You remember on Wednesday (day 2). Inject Wednesday morning at your normal dose. Your next injection is 7 days later, Friday.
If you remember after 5 days:
Skip this dose entirely. Resume your normal injection schedule the following week on your original injection day.
Example: You missed Monday's injection and don't remember until Saturday (day 5). Skip it. Resume Monday next week at your normal dose.
Why this matters: GLP-1s have a half-life of 7 days. After 5 days, ~75% of your prior dose is still active. Injecting late doesn't restart tolerance or help you "catch up"; it just shifts your cycle. After 7+ days, receptors reset partially, and re-injecting is less valuable than simply resuming on schedule.
If you remember within 4-6 hours:
Inject immediately. Resume daily schedule the next day, maintaining 24-hour spacing between doses (or 12 hours if you inject twice daily).
If you remember more than 6 hours later:
Skip that dose. Resume your normal schedule the next day. Do not double up.
Example: Your evening GH peptide injection is scheduled 8 PM. You remember at 11 PM. Skip it. Resume tomorrow evening at 8 PM.
Why this matters: GH secretagogues peak at 30-60 minutes post-injection and have effective windows of 4-6 hours. Injecting more than 6 hours late provides minimal benefit. Doubling the next day creates unnecessary receptor stress.
If you remember within 12 hours:
Inject immediately. Resume daily schedule the next day.
If you remember more than 12 hours later:
Skip that dose. Resume your normal schedule the next day.
Why this matters: BPC-157 works cumulatively; it doesn't have acute "peaks" like GLP-1s. One missed dose has minimal impact on overall results. The important factor is consistency over weeks and months, not catching up on individual doses.
If you remember within 24 hours:
Inject immediately. Resume your normal schedule.
If you remember more than 24 hours later:
Skip the dose. Resume normally.
Why this matters: Immune peptides build over time. Single doses miss minimal impact. Consistency matters far more than catching up.
These peptides are typically dosed daily or 3-5x weekly and work cumulatively.
Within 24 hours: Inject immediately, resume schedule.
After 24 hours: Skip, resume normally.
No catching up. Single doses don't affect final outcome significantly.
Scenario 1: Missed one GLP-1 injection
Scenario 2: Missed multiple doses across a month
Scenario 3: Missed dose due to injury/illness
MyProtocolStack's app sends automated reminders 1 day and 1 hour before your scheduled injection. Set these notifications to avoid missing doses. The app also tracks which doses you've completed, making it obvious if you've missed one.
Set a backup reminder: phone calendar alarm + a physical reminder (marked on your bathroom mirror, for example).
If you're traveling across time zones:
Document time zone changes with MyProtocolStack so your timeline remains clear.
Log every missed dose in MyProtocolStack:
Over time, this data reveals patterns. If you consistently miss evening doses, shift to morning injections. If you miss during work stress periods, set stronger reminders for those weeks.
Missed doses are a normal part of long-term protocols. Knowing the exact rule for your compound prevents panic and ensures you take the right action immediately.
