CJC-1295 vs MOTS-c.
Evidence, risk, regulatory flags, cost, and vendor coverage compared side by side. We don’t sell peptides — we help you choose between them.
Which should you research first?
Start with CJC-1295, then use the table to confirm fit.
CJC-1295 is the cleaner first read based on the current evidence, risk, and regulatory data stored for this pair. The right answer can still change if your goal, sport testing status, vendor constraints, or monitoring tolerance makes the other option a better fit.

01 · At a glance
| Decision factor | CJC-1295 | MOTS-c |
|---|---|---|
| Primary fit | muscle growth & strength and fat loss & metabolism comparisons | fat loss & metabolism and longevity & anti-aging comparisons |
| Evidence | Tier B | Tier C |
| Risk | high | high |
| Experience level | intermediate | advanced |
| Budget tier | mid | premium |
| Administration route | subcutaneous | subcutaneous |
02 · Use case & timing
| Decision factor | CJC-1295 | MOTS-c |
|---|---|---|
| Goal fit | Muscle Growth & Strength, Fat Loss & Metabolism, GH Axis Optimization | Fat Loss & Metabolism, Longevity & Anti-Aging |
| What users compare it for | Sustained GH and IGF-1 elevation; body composition modulation (long-horizon, not well-established for consumer outcomes). | Preclinical: improved insulin sensitivity, metabolic regulation, exercise performance in mice. |
| Onset timeline | Biomarker effects persist multiple days; IGF-1 elevations up to ~2 weeks after single dose. | Metabolic endpoints assessed over days to weeks in mice; exercise performance improvements after ~10 days. |
| Main tradeoff | Evidence is stronger than most compounds in this category, but route, side effects, and vendor fit still matter. | Potential upside comes with much more safety and screening caution than lower-risk alternatives. |
03 · Safety & restrictions
| Decision factor | CJC-1295 | MOTS-c |
|---|---|---|
| Adverse effects | Injection-site reactions, headache, diarrhea, flushing, transient hypotension at higher doses. | FDA: no identified human exposure data; significant immunogenicity/characterization risks. |
| Contraindications | GH-axis stimulation risks: glucose intolerance, theoretical neoplasia concerns with elevated IGF-1. | No human data. |
| Interaction notes | Monitor insulin/glucose sensitivity, thyroid axis, and cortisol/prolactin. Trials report no significant cortisol/prolactin/TSH/LH increases at 60 µg/kg single dose. | Unknown. |
| Regulatory status | Not approved | Not approved |
| FDA flag | FDA compounding caution | FDA compounding caution |
| WADA status | WADA S2 | Status unclear |
04 · Age & monitoring
| Decision factor | CJC-1295 | MOTS-c |
|---|---|---|
| Supported age ranges | 25-34, 35-44, 45-54 | No age guidance yet |
| Life-stage note | Midlife is where GH-restoration framing is most often used, but evidence and long-term safety remain limited. | Not yet documented |
| Monitoring burden | high | Not specified |
| Follow-up cadence | Reassess at startup and then roughly every few months if continuing. | Not yet documented |
05 · Cost & sourcing
| Decision factor | CJC-1295 | MOTS-c |
|---|---|---|
| Typical cycle cost | $143.98 | €33.02 |
| Estimated monthly cost | $47.99 | €33.02 |
| Cost confidence | High confidence | High confidence |
06 · Before you buy
| Decision factor | CJC-1295 | MOTS-c |
|---|---|---|
| Tracked vendor listings | 3 listings | 3 listings |
| Sourcing note | At least one listing is a blend rather than a clean standalone product, so review the product page carefully. | Product format varies by listing, so double-check route, concentration, and presentation. |
