Peptide A
MuscleLimited human evidence

CJC-1295 / Ipamorelin

Growth-hormone secretagogue combination studied for stimulating endogenous GH pulses in research contexts.

Research strength40/100
Community popularity80/100
SmartPeptide composite56/100
What research shows

Both compounds have pharmacology data in healthy adults showing increased endogenous GH pulses without affecting prolactin or cortisol much. Some PK/PD trials are published.

What's still experimental

Outcome trials (body composition, recovery, longevity) are sparse and mostly small. Long-term safety of repeated GH stimulation is not well established.

Known risks

Carries risks similar to elevated GH (insulin resistance, edema). Not approved for general use.

Reported side effects

Water retention, injection-site irritation, headaches.

Peptide B
LongevityLimited human evidence

Sermorelin

GHRH analog (first 29 amino acids of human GHRH). Stimulates endogenous growth hormone release. Approved for pediatric GH deficiency, widely used off-label in adults.

SmartPeptide composite58/100
What research shows

Pediatric GH deficiency: FDA approved (now discontinued for marketing in the US but evidence stands). Stimulates GH/IGF-1 release in healthy adults short-term.

What's still experimental

Adult anti-aging use, body recomposition, and long-term safety. Most clinic-marketed indications are NOT FDA-approved.

Known risks

Hyperglycemia, fluid retention, hypothyroidism risk, possible carpal tunnel symptoms. Long-term cancer risk theoretical but understudied.

Reported side effects

Injection-site reactions, headache, flushing, transient sleepiness, dizziness.
