Introduction
Starting peptide therapy is exciting—but also comes with questions. "When will I see results?" "What should I feel?" "Is this normal?"
After helping thousands of patients at Lake Hills Pharmacy, I can tell you: everyone's journey is a bit different. But there are common patterns.
Think of this guide as your roadmap for the first month. I'll walk you through what to expect week by week, what's normal versus concerning, and how to track your progress effectively.
By the end, you'll know exactly what to watch for and when to reach out for help.
Week 1: Getting Started
The first week is all about establishing your routine and getting comfortable with the process.
What Happens This Week
Your main tasks:
- ✓ First injection (or dose)
- ✓ Establish dosing routine
- ✓ Get comfortable with technique
- ✓ Monitor for immediate reactions
What you might feel:
- Excitement/nervousness
- Possibly nothing yet (most peptides take time)
- Mild injection site reactions
- Some peptides (like semaglutide) may cause early appetite changes
Week 1 Day-by-Day
Day 1: Your First Dose
Common thoughts: "Did I do this right?" "When will it work?" "Should I feel something?"
Reality: Most peptides don't cause immediate effects. That's normal!
Exceptions:
- Semaglutide: Some people notice reduced appetite within 24-48 hours
- Selank/Semax (nasal): May feel calmer/focused within hours
- NAD+ (IV): Often feel energized immediately
Day 2-3: Building Confidence
What's happening:
- Your injection technique improves
- Less nervousness
- Still probably no major effects
Common questions: "Is this even working?" (It takes time!)
Day 4-7: Establishing Routine
What's happening:
- Routine becomes habit
- Injection anxiety fades
- Still early for major results
Tips for Week 1 success:
- Set phone reminders for dosing times
- Keep a simple log (date, time, how you feel)
- Don't expect dramatic changes yet
- Focus on consistency
Week 1 Side Effects: What's Normal
✅ Normal and expected:
- Mild redness at injection site (fades in hours)
- Slight stinging during injection
- Minimal bruising
- Nervousness/anticipation
⚠️ Worth mentioning to provider:
- Persistent pain at injection site
- Bruising larger than a quarter
- Nausea (if using GLP-1 agonists like semaglutide)
- Mild headache
🚨 Call provider immediately if:
- Severe allergic reaction (rash, difficulty breathing, swelling)
- Severe pain
- Signs of infection (red streaks, warmth, fever)
💡 Pro Tip from Dr. John
"The first week, focus on mastering the technique and establishing your routine. Don't worry about results yet. Most patients I talk to in Week 1 are anxious about whether it's 'working.' Give it time! By Week 3, you'll have a much better sense."
Week 2: Early Effects
This is when some peptides start showing subtle effects. Emphasis on subtle!
What Happens This Week
Potential early signs (peptide-dependent):
Weight Loss Peptides (Semaglutide, Tirzepatide):
- Reduced appetite becomes more noticeable
- Feeling full faster
- Possible mild nausea (usually improves)
- Scale might show 1-3 pound loss
Injury Recovery Peptides (BPC-157, TB-500):
- Pain might reduce slightly
- Swelling may decrease
- Not dramatic yet, but trending positive
Cognitive Peptides (Selank, Semax):
- Steadier mood
- Clearer thinking
- Better stress management
- More consistent than Week 1
GH Peptides (Sermorelin, CJC/Ipamorelin):
- Sleep quality might improve
- Slightly better recovery from workouts
- Still early for body composition changes
NAD+ / Anti-Aging:
- Energy levels stabilizing
- Better mental clarity
- Improved stamina
Week 2 Reality Check
What you MIGHT notice:
- 10-20% improvement in target symptom
- More consistent effects than Week 1
- Better tolerance of side effects
- Growing confidence in routine
What you WON'T see yet:
- Dramatic transformations
- 20-pound weight loss
- Complete injury healing
- Radical energy changes
The key: Progress, not perfection. Small wins count!
Managing Week 2 Side Effects
For GLP-1 agonists (semaglutide):
- Nausea is common this week
- Eat smaller, more frequent meals
- Avoid greasy/spicy foods
- Stay hydrated
- Usually improves by Week 3
For all peptides:
- Injection sites might be slightly tender (rotate!)
- Keep tracking reactions
- Report persistent issues
Week 3-4: Seeing Results
This is when peptides typically start showing measurable benefits.

- ✓ GI side effects improving
- ✓ Establishing new eating patterns
Injury Recovery Peptides:
- ✓ 30-40% pain reduction (common)
- ✓ Improved function

- ✓ More energy during day
NAD+ / Anti-Aging:
- ✓ Sustained energy improvements

Week 3-4 Milestones
This is when you should:
- See objective improvements
- Feel confident it's working
- Have measurable changes (weight, pain scale, sleep quality)
- Be ready for follow-up with provider
If you're NOT seeing ANY improvement by Week 4:
- Don't panic—some people are slower responders
- Review your dosing (are you being consistent?)
- Check your storage (is peptide stored properly?)
- Schedule provider follow-up (may need dose adjustment)
Realistic Expectations by Peptide
Let me give you specific Week 3-4 expectations:
Semaglutide/Weight Loss:
- Typical: 4-8 pounds lost, 50% reduction in appetite
- Excellent response: 10+ pounds lost, very little hunger
- Poor response: 2 pounds or less, minimal appetite change
BPC-157/Injury Recovery:
- Typical: 30-50% pain reduction, improved function
- Excellent response: 60%+ pain reduction, back to some activities
- Poor response: < 20% improvement, still very limited
Selank/Cognitive:
- Typical: Noticeable calm, better focus, reduced anxiety
- Excellent response: "Best I've felt in years," major improvement
- Poor response: Minimal to no change in symptoms
CJC/Ipamorelin/GH:
- Typical: Better sleep, faster recovery, subtle energy boost
- Excellent response: Deep sleep, rapid recovery, noticeable body changes
- Poor response: Minimal sleep improvement, no obvious benefits
Common Side Effects Timeline
Let me break down when side effects typically appear and resolve:
Week 1 Side Effects
Most Common:
- Injection site reactions (100% normal)
- Nervousness (psychological)
- Mild bruising
GLP-1 specific:
- Mild nausea (20-30% of users)

Key point: If side effects are GETTING WORSE after Week 3, that's unusual. Contact provider.
Side Effect Frequency Chart
| Side Effect | Week 1 | Week 2 | Week 3 | Week 4 | |-------------|---------|---------|---------|---------| | Injection site reaction | 90% | 60% | 30% | 10% | | Nausea (GLP-1) | 30% | 50% | 30% | 10% | | Fatigue | 20% | 30% | 10% | 5% | | Headache | 15% | 20% | 10% | 5% | | Constipation (GLP-1) | 5% | 15% | 10% | 10% |
When to Adjust Expectations
Sometimes, peptides don't work as expected. Here's how to evaluate:
Reasons for Slower Response
1. Insufficient dose
- Some people need higher doses
- Provider may titrate up
2. Inconsistent dosing
- Missing doses reduces effectiveness
- Set better reminders
3. Storage issues
- Check that peptide hasn't been heat-exposed
- Verify proper refrigeration
4. Dietary/lifestyle factors
- Weight loss peptides work best with calorie awareness
- Recovery peptides work best with proper rehab
- Can't out-peptide a bad diet/lifestyle
5. Individual variation
- Some people are slow responders (15-20%)
- May take 6-8 weeks to see effects
- Still worth continuing
When to Consider Dose Adjustment
Talk to provider about increasing dose if:
- Week 4, minimal to no improvement
- You're being consistent with dosing
- No side effects at current dose
- Storage has been proper
Typical titration schedule (using semaglutide as example):
- Week 1-4: 0.25 mg weekly
- Week 5-8: 0.5 mg weekly
- Week 9-12: 1 mg weekly
- Week 13+: Up to 2.5 mg weekly as needed
When to Consider Switching Peptides
Consider switching if:
- No response by Week 6-8 at appropriate dose
- Intolerable side effects
- Better options available for your goal
- Cost is prohibitive

FAQ
Q: I'm in Week 2 and don't feel anything. Should I be worried?
A: Not yet! Most peptides take 3-4 weeks for noticeable effects. Be patient and stay consistent.
Q: When will I see my target result (e.g., 30-pound weight loss)?
A: For weight loss, expect 1-2 pounds per week. So 30 pounds = 15-30 weeks. For injury recovery, 8-12 weeks for significant healing.
Q: Can I increase my dose if it's not working fast enough?
A: Only with provider approval. Don't self-adjust dosing. There are reasons for titration schedules.
Q: What if side effects get worse instead of better?
A: Contact your provider. This is unusual and may indicate you need a dose reduction or alternative.
