Comparison

CJC-1295 vs Lion's Mane

Side-by-side of CJC-1295 and Lion's Mane. 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

Lion's Mane

  • Edible medicinal mushroom containing NGF-stimulating hericenones and erinacines
  • Mori 2009 trial (n=30) in mild cognitive impairment showed cognitive improvement at 3 g/day for 16 weeks, reversing 4 weeks after discontinuation
  • Saitsu 2019 (n=31) in older adults reported MoCA improvements at 3.2 g/day over 12 weeks
  • Multiple small mood trials suggest reduced anxiety and depression scores at 1 to 4 g/day extract
  • Mechanistic case rests on NGF stimulation and remyelination support; in vivo human NGF measurement is absent
  • Product quality varies substantially; mycelium-on-grain products can be over 50% grain by weight

Side-by-side

Attribute CJC-1295 Lion's Mane
Category peptide natural
Also known as CJC-1295 DAC, CJC-1295 no-DAC, Mod GRF 1-29, tesamorelin analog Hericium erinaceus, Yamabushitake, Bearded Tooth, Hou Tou Gu
Half-life (hr) 168 6
Typical dose (mg) 0.1 1000
Dosing frequency weekly (DAC); 1-3x daily (non-DAC) 1 to 2 times daily
Routes subcutaneous oral
Onset (hr) 1 168
Peak (hr) 3 1344
Molecular weight 3367.83 -
Molecular formula C152H252N44O42 mixed extract
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. Hericenones and erinacines stimulate NGF mRNA expression and NGF protein release in cultured neurons; secondary anti-inflammatory and remyelination-supportive activity in preclinical models.
Legal status Not FDA approved; research-use-only grey market; banned by WADA Dietary supplement and food worldwide; unscheduled and unrestricted
WADA status banned allowed
DEA / Rx Not FDA approved; not scheduled; research-chemical status OTC supplement and food
Pregnancy Insufficient data; not recommended Insufficient data for routine supplementation; consumed historically as food without documented harm

  • 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)

  • corticosteroids: blunt GH-axis response; reduce expected efficacy(moderate)

Lion's Mane

Common side effects

  • mild GI upset
  • occasional skin rash
  • contact dermatitis (rare)

Contraindications

Which Should You Take?

Lion's Mane 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 post-training recovery, pick CJC-1295.
  • If your priority is growth-hormone axis, pick CJC-1295.
  • If your priority is focus or working memory, pick Lion's Mane.
  • If your priority is nerve health, pick Lion's Mane.

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

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