Comparison

CJC-1295 vs DHEA

Side-by-side of CJC-1295 and DHEA. 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

DHEA

  • Adrenal androgen precursor; serum DHEA-S declines progressively after the third decade of life
  • OTC dietary supplement in US under DSHEA 1994; prescription in EU, UK, Canada, Australia
  • FDA approved as Intrarosa (6.5 mg vaginal insert) for postmenopausal dyspareunia in 2016
  • Acts as tissue-specific prohormone converted intracrinologically to testosterone and estrogens
  • Best evidence: adrenal insufficiency replacement and vaginal atrophy; weaker on cognition and longevity
  • WADA banned in competitive sport; banned in NCAA, MLB, NFL, IOC settings

Side-by-side

Attribute CJC-1295 DHEA
Category peptide hormone
Also known as CJC-1295 DAC, CJC-1295 no-DAC, Mod GRF 1-29, tesamorelin analog dehydroepiandrosterone, prasterone, Intrarosa
Half-life (hr) 168 12
Typical dose (mg) 0.1 25
Dosing frequency weekly (DAC); 1-3x daily (non-DAC) daily, typically morning
Routes subcutaneous oral, vaginal, topical
Onset (hr) 1 1
Peak (hr) 3 1
Molecular weight 3367.83 288.42
Molecular formula C152H252N44O42 C19H28O2
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. Steroid prohormone converted intracrinologically to testosterone and estrogens in target tissues; also exerts direct effects via sigma-1 receptor, GABA-A modulation, and glucocorticoid receptor interaction.
Legal status Not FDA approved; research-use-only grey market; banned by WADA OTC supplement in US (DSHEA 1994); prescription in EU, UK, Canada, Australia
WADA status banned banned
DEA / Rx Not FDA approved; not scheduled; research-chemical status OTC supplement in US (not scheduled); Rx in EU, UK, Canada, Australia
Pregnancy Insufficient data; not recommended Contraindicated in pregnancy
CAS 446262-90-4 53-43-0

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)

DHEA

Common side effects

  • acne
  • oily skin
  • hirsutism (women)
  • gynecomastia (men, higher doses)
  • irritability
  • insomnia

Contraindications

  • hormone-sensitive cancer (breast, ovarian, prostate)
  • active liver disease
  • uncontrolled lipid disorder
  • pregnancy and lactation

Interactions

  • warfarin: case reports of altered INR; monitor(moderate)
  • estrogens (HRT): additive estrogenic effect via conversion; monitor(moderate)
  • insulin: may improve insulin sensitivity slightly; monitor glucose(minor)
  • anastrozole: may reduce DHEA-derived estrogen; clinical relevance unclear(minor)

Which Should You Take?

DHEA comes out ahead for most readers on the criteria we weight: 2 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-A outcome catalogued. CJC-1295 is the right call when one of the conditionals below applies.

  • If your priority is post-training recovery, pick CJC-1295.
  • If your priority is growth-hormone axis, pick CJC-1295.
  • If your priority is hormonal optimization, pick DHEA.
  • If your priority is healthspan extension, pick DHEA.

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

Default choice: DHEA. Lower friction to source, a Tier-A evidence outcome catalogued, and broader goal coverage. Reach for CJC-1295 only if your priority sits squarely in the goals it owns above.
