You've seen mentions of BPC-157, semaglutide, growth hormone peptides, and dozens of others, but you don't have an all in one reference showing all your options organized by category and purpose.
Here's what you need: a complete, organized list of injectable peptides broken down by category.
Healing peptides, muscle-building peptides, fat loss peptides, anti-aging peptides, cognitive enhancement, sexual health.
Each one with its primary uses, typical dosing, and what you need to know.
This guide provides exactly that - the most comprehensive injectable peptide list available, organized by function.
You'll see every major peptide in each category, understand what differentiates them, learn standard dosing protocols, and know which peptides work best for your specific goals.
Let's start with healing and recovery peptides - the most popular category.

How to choose the right injectable peptide
With so many options, selection requires strategy.
Step 1: Define your primary goal
Ask yourself:
What's my #1 objective? (healing, muscle, fat loss, anti-aging, etc.)
Is this acute (injury) or ongoing (body composition, longevity)?
What timeline am I working with?
Match goal to category:
Injury = Healing peptides
Build muscle = Growth hormone peptides
Lose fat = Fat loss peptides
Look younger = Anti-aging + skin peptides
Better sex = Sexual health peptides
Sharper mind = Cognitive peptides
Step 2: Consider your experience level
Beginners start with:
BPC-157 (healing)
CJC-1295/Ipamorelin (muscle/anti-aging)
Semaglutide (fat loss, if you can get prescription)
Intermediate users can add:
TB-500 (healing)
AOD 9604 (fat loss)
PT-141 (sexual health)
Advanced users explore:
IGF-1 LR3 (muscle)
Multiple peptide stacks
Specialty peptides for specific conditions
Step 3: Evaluate safety profile
Safest peptides (extensive use, minimal sides):
BPC-157
TB-500
CJC-1295
Ipamorelin
GHK-Cu
Use with caution (more sides or less data):
GHRP-6 (prolactin increase)
Hexarelin (desensitization, cortisol)
IGF-1 LR3 (hypoglycemia risk)
Melanotan II (permanent tanning, nausea)
Step 4: Consider practical factors
Injection frequency:
Once weekly: Semaglutide, Tirzepatide
Daily: AOD 9604, Epithalon (during cycles)
Twice daily: BPC-157, KPV
2-3x daily: GHRP-6, GHRP-2
Choose based on your compliance: If you won't inject 3x daily consistently, pick different peptide.
Cost considerations:
Expensive: Semaglutide, Tirzepatide, Cerebrolysin
Moderate: TB-500, CJC-1295/Ipamorelin
Affordable: BPC-157, Melanotan II
Use our peptide cost calculator to budget properly.
Step 5: Stack strategically (if combining)
Synergistic stacks:
BPC-157 + TB-500 (healing)
CJC-1295 + Ipamorelin (muscle/anti-aging)
Semaglutide + CJC/Ipa (fat loss with muscle preservation)
Semax + Selank (cognitive + anxiety)
Avoid redundancy:
Don't stack multiple GHRPs (Ipamorelin + GHRP-6 + Hexarelin = unnecessary)
Don't stack multiple GLP-1s (Semaglutide + Tirzepatide = no added benefit)
See our peptide stacks guide for complete protocols.
Injection best practices for all peptides
Regardless of which peptide you choose, proper injection technique matters.
Subcutaneous injection (most peptides)
Best sites:
Abdomen (2+ inches from navel)
Thighs (outer)
Love handles
Back of arms (harder to reach)
Technique:
Clean injection site with alcohol
Pinch skin to create fold
Insert needle at 45-90 degree angle
Inject slowly (2-3 seconds)
Remove needle, apply pressure
Intramuscular injection (some peptides)
Best sites:
Glutes (upper outer quadrant)
Thighs (vastus lateralis)
Deltoids (shoulders)
Technique:
Clean injection site
Insert needle at 90 degrees (deeper than SubQ)
Aspirate (pull back plunger slightly to check for blood)
Inject slowly
Remove and apply pressure
Rotation and site management
Rotate injection sites:
Never use same spot twice in one week
Have 8-10 sites in rotation
Track sites if injecting multiple times daily
Avoid:
Injecting into scar tissue
Sites with visible inflammation
Areas with lumps from previous injections
Learn complete technique in our peptide injections guide.
Reconstitution and storage
Reconstitution:
Use bacteriostatic water (0.9% benzyl alcohol)
Calculate properly based on vial size
Inject water slowly down side of vial (don't spray directly on powder)
Swirl gently, don't shake
Storage after reconstitution:
Refrigerate at 2-8°C (36-46°F)
Protect from light
Use within 28-30 days for most peptides
Discard if cloudy or discolored
See our peptide reconstitution calculator for exact measurements and our how to reconstitute peptides guide for step-by-step instructions.
Safety considerations across all injectable peptides
General safety principles apply regardless of which peptide you use.
Start low, go slow
For any new peptide:
Start at lowest effective dose
Assess tolerance for 1-2 weeks
Increase gradually if needed
Don't rush to maximum dose
Example progression:
BPC-157: Start 250mcg 2x daily, can increase to 500mcg 2x daily if needed
CJC/Ipa: Start 200mcg each, can increase to 300mcg if no sides
Monitor for side effects
Common across peptides:
Injection site reactions (redness, swelling)
Headaches (especially GH peptides initially)
Water retention (GH peptides, GLP-1s)
Nausea (GLP-1s, Melanotan II)
When to stop:
Severe allergic reaction (hives, difficulty breathing)
Persistent severe side effects
Unexplained symptoms
Lack of improvement after reasonable trial
Get baseline and follow-up bloodwork
Before starting peptides:
Basic metabolic panel
Liver and kidney function
Thyroid panel
Relevant hormones (testosterone, IGF-1, etc.)
During use:
Follow-up testing every 3-4 months
Monitor markers relevant to your peptides
Adjust protocols based on results
Legal and regulatory awareness
Understand status:
FDA-approved peptides require prescription
Research peptides are gray area (legal to possess, not approved for human use)
Athletic drug testing includes most peptides (WADA banned)
See our are peptides legal guide for complete regulatory information.
Source quality products
Only use peptides with:
Third-party testing (Certificate of Analysis)
95% purity (ideally 98%+)
Proper storage and shipping (cold chain)
Reputable supplier
See our best peptide vendors guide for sourcing quality peptides.
