Comparison

CJC-1295 vs Curcumin

Side-by-side of CJC-1295 and Curcumin. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.

Effects at a glance

CJC-1295

  • GHRH analog that binds the GHRH receptor on pituitary somatotrophs to release endogenous GH
  • DAC variant has ~7 day half-life via albumin binding; non-DAC variant ~30 minutes
  • Teichman 2006 trial showed sustained 2 to 10 fold IGF-1 elevation at 60 to 250 mcg/kg DAC dosing
  • Anecdotal protocols pair non-DAC CJC-1295 with Ipamorelin to mimic pulsatile GH release
  • Side effects: water retention, numbness or tingling at injection site, vivid dreams, transient flushing
  • No completed phase III RCTs; research-use-only and not FDA approved

Curcumin

  • Reduces osteoarthritis knee pain comparable to ibuprofen at 1500 mg/day enhanced formulation
  • Modest antidepressant effect (SMD ~0.34) as monotherapy or SSRI adjunct in major depression
  • Standard curcumin has ~3% bioavailability; Meriva, BCM-95, Theracurmin shift absorption 5-30 fold
  • Inhibits NF-kB and COX-2; reduces hs-CRP, IL-6, TNF-alpha in chronic inflammation
  • Antiplatelet effect at higher doses; meaningful interaction with warfarin and DOACs
  • Iron chelation can contribute to deficiency in already-marginal patients

Side-by-side

Attribute CJC-1295 Curcumin
Category peptide natural
Also known as CJC-1295 DAC, CJC-1295 no-DAC, Mod GRF 1-29, tesamorelin analog turmeric extract, diferuloylmethane
Half-life (hr) 168 7
Typical dose (mg) 0.1 500
Dosing frequency weekly (DAC); 1-3x daily (non-DAC) 1 to 2 times daily with meals
Routes subcutaneous oral
Onset (hr) 1 2
Peak (hr) 3 4
Molecular weight 3367.83 368.38
Molecular formula C152H252N44O42 C21H20O6
Mechanism Binds the GHRH receptor on pituitary somatotrophs, stimulating pulsatile growth-hormone release. The DAC modification extends plasma residence by tethering the peptide to serum albumin via a maleimide-cysteine bond. Inhibits NF-kB transcription factor, COX-2, and lipoxygenase; activates AMPK and Nrf2; modulates JAK-STAT and PI3K-Akt kinase signaling. Pleiotropic anti-inflammatory and antioxidant effects.
Legal status Not FDA approved; research-use-only grey market; banned by WADA Dietary supplement (global)
WADA status banned allowed
DEA / Rx Not FDA approved; not scheduled; research-chemical status Not scheduled
Pregnancy Insufficient data; not recommended Culinary turmeric is safe; supplemental curcumin best avoided in pregnancy

Safety profile

CJC-1295

Common side effects

  • injection-site reactions
  • water retention
  • numbness or tingling at injection site
  • vivid dreams
  • transient flushing
  • head pressure or mild headache

Contraindications

  • pregnancy
  • active malignancy
  • diabetic retinopathy (theoretical)
  • history of pituitary tumor

Interactions

  • Ipamorelin: synergistic GH release; commonly co-administered in anecdotal protocols(minor)
  • insulin: GH-induced insulin resistance can shift glycemic control over weeks(moderate)
  • corticosteroids: blunt GH-axis response; reduce expected efficacy(moderate)

Curcumin

Common side effects

  • nausea
  • diarrhea
  • dyspepsia
  • yellow stool (benign)

Contraindications

  • active gallstones (curcumin stimulates gallbladder contraction)
  • severe biliary obstruction
  • scheduled elective surgery (discontinue 1-2 weeks prior)

Interactions

  • warfarin and DOACs: additive antiplatelet and anticoagulant effects; meaningful bleeding risk at 1000+ mg/day(major)
  • aspirin and NSAIDs: additive antiplatelet effect(moderate)
  • tacrolimus and cyclosporine: CYP3A4 and P-gp modulation may alter drug levels(moderate)
  • iron supplements: curcumin chelates iron; can contribute to deficiency in marginal patients(moderate)
  • chemotherapy agents: potential interference with multiple agents; coordinate with oncology team(major)

Which Should You Take?

Curcumin comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-B outcome catalogued. CJC-1295 is the right call when one of the conditionals below applies.

  • If your priority is growth-hormone axis, pick CJC-1295.
  • If your priority is body composition, pick CJC-1295.
  • If your priority is healthspan extension, pick Curcumin.
  • If your priority is joint health, pick Curcumin.

Edge case: If you want to avoid research-only / gray-market sourcing, Curcumin is the more accessible choice.

Default choice: Curcumin. Lower friction to source, and broader goal coverage. Reach for CJC-1295 only if your priority sits squarely in the goals it owns above.
