Introduction: The Evolution of Peptide Therapy
Peptides are no longer just for bodybuilders. In 2026, peptide therapy has revolutionized functional medicine, offering targeted solutions for everything from rapid weight loss and metabolic health to injury repair and anti-aging.
However, the landscape changes fast. While classics like BPC-157 remain staples, new powerhouses like SLU-PP-332 and Retatrutide are rewriting the rules. This guide provides the essential “Master Chart” you need to understand these options safely.

The 2026 Master Peptide Chart: Typical Dosages & Uses
Note: The following information is for educational purposes only. Dosage varies significantly based on body weight, health status, and medical history. Always consult Dr. Kumar at LifeWell MD before starting any protocol.
| Peptide Category | Peptide Name | Primary Goal | Common Protocol / Frequency |
| Metabolic / Fat Loss | SLU-PP-332 | Fat Loss & Endurance (Exercise Mimetic) | Typically 250mcg – 2mg daily (Injectable) or Oral equivalents. See detailed guide below. |
| Tirzepatide | Weight Loss & Insulin Control | Weekly injection. Starts low (2.5mg) and titrates up monthly. | |
| Retatrutide | “Triple Agonist” for Rapid Fat Loss | Emerging: Weekly dosing, highly potent. Strict medical supervision required. | |
| AOD-9604 | Targeted Fat Loss | 250mcg – 300mcg daily (usually morning, fasted). | |
| Healing / Repair | BPC-157 | Injury Recovery & Gut Health | 250mcg – 500mcg, twice daily. |
| TB-500 | Inflammation & Flexibility | Loading phase (2-5mg/week) followed by maintenance. | |
| Sexual Health | PT-141 | Libido & Arousal (Men & Women) | 1mg – 2mg taken 45 mins prior to activity. |
| Anti-Aging | CJC-1295 / Ipamorelin | Growth Hormone & Sleep | 100mcg/100mcg blend, taken nightly (fasted). |
Spotlight on Trending Peptides
1. SLU-PP-332: The “Exercise Mimetic”
This is currently the most talked-about peptide in longevity circles. Unlike stimulants that just burn calories, SLU-PP-332 works by activating the ERRα pathway, essentially tricking your muscles into thinking they are exercising.
- Best For: Individuals looking to preserve muscle while stripping fat, or those who cannot exercise vigorously due to injury.
- Deep Dive: For a complete breakdown on how this works and oral vs. injectable options, read our specific guide: Understanding SLU-PP-332: Key Information and Dosage Guidance.
2. Tirzepatide & Retatrutide
These are the heavy hitters of weight loss. While Semaglutide acts on one receptor (GLP-1), Tirzepatide acts on two, and the new Retatrutide acts on three.
- The Warning: These are potent. “Eyeballing” the dose can lead to severe nausea and hypoglycemia. Accurate calculation is non-negotiable.
3. BPC-157: The Wolverine Peptide
BPC-157 remains the gold standard for soft tissue repair. It is often “stacked” with TB-500 for synergistic effects.
The Math: How to Calculate Your Dose
Getting the dose right starts with Reconstitution. Most peptides come as a lyophilized (freeze-dried) powder that must be mixed with Bacteriostatic Water.
[PASTE YOUR INFOGRAPHIC HERE]
(Alt Text: Infographic showing the math of mixing 5mg peptide powder with 2ml water to get a 2.5mg/ml concentration)
The Formula:
Total mg of Peptide ÷ mL of Water = Concentration
Example:
- You have a 5mg vial of BPC-157.
- You add 2mL of bacteriostatic water.
- Concentration = 2.5mg per mL.
- If your syringe has 100 units per mL, then 10 units = 250mcg.
The “Visual Meter” Trick
Many patients struggle with the math.
- Use a Peptide Calculator: There are many free apps available, but we recommend asking your provider for a specific “Units to Draw” number to avoid errors.
- Start Low: Always start at the lowest end of the dosing chart (Titration). You can add more, but you cannot take it out.
Storage & Safety Protocols
- Before Mixing: Store powder in the freezer (-20°C) for long-term stability.
- After Mixing: ALWAYS refrigerate (36-46°F). Reconstituted peptides are fragile.
- Shelf Life: Once mixed, most peptides degrade after 3-4 weeks. If the solution turns cloudy, discard it immediately.
- Hygiene: Always wipe the vial top with an alcohol swab. Never reuse a syringe.
Why “Internet Dosing” is Risky
While charts are helpful, biochemistry is individual.
A dose that shreds fat for a 200lb male might cause severe side effects for a 130lb female. Furthermore, sourcing is critical. “Research Chemicals” sold online are often under-dosed or contaminated with heavy metals.

Frequently Asked Questions (FAQ)
1. What is the difference between SLU-PP-332 and Ozempic?
Ozempic (Semaglutide) is an appetite suppressant. SLU-PP-332 is a metabolic enhancer that improves mitochondrial function. They can sometimes be used together, but they work through completely different pathways.
2. Can I mix different peptides in the same syringe?
Generally, yes—but not all. BPC-157 and TB-500 are often mixed. However, acidic peptides can damage fragile ones. Always check with your provider before creating your own “blends.”
3. How do I know if my dosage is too high?
Common signs of overdose include injection site redness, lethargy, water retention (common with GH secretagogues), or lightheadedness. If these occur, reduce the dose or stop immediately.
4. Is SLU-PP-332 safe for older men?
Yes, it is showing great promise for preventing age-related muscle loss (sarcopenia). Read more in our article: Best Peptide Stack for Men Over 60.

Final Words: Stop Guessing with Your Health
Peptides are powerful tools, but they require precision. Whether you are looking to heal an old injury, optimize your metabolism with SLU-PP-332, or regain your edge in the bedroom, the protocol matters more than the product.
