Compound Profile
HCG Diet
HCG should not be promoted for weight loss: FDA warns against HCG weight loss products, and clinical evidence shows weight loss comes from severe calorie restriction rather than HCG.

FDA enforcement warning
The FDA has warned that over-the-counter HCG weight-loss products are illegal and unsupported, and HCG diet plans often pair the product with unsafe severe calorie restriction.
- HCG is not approved for over-the-counter weight loss.
- This profile is a warning-oriented reference, not a diet recommendation.

How evidence grades work
Each grade reflects the strength and consistency of published human evidence — not marketing claims. Grades are based on study count, design quality, effect size, consistency, and recency.
A
Strong
Multiple RCTs, consistent direction, adequate effect size
B
Moderate
Some RCTs or consistent observational data in humans
C
Preliminary / Mixed
Animal or in-vitro only, or conflicting human data
D
Traditional / Theoretical
Traditional use only; no controlled human trials

Compound profile context
How to interpret HCG Diet
HCG Diet dosage by use case, onset and duration, safety limits, and interactions for avoid, graded against research. Strong Human Evidence research evidence. Use this compound profile to understand mechanism, evidence quality, and practical safety context before comparing products or building a stack. A biochemical pathway connection can be useful for discovery, but it is not the same as proven benefit in humans.
When reviewing HCG Diet, separate the active molecule from the product category around it. Dose form, absorption, extract standardization, medication interactions, and individual sensitivity can change the real-world risk-benefit picture.
For supplement planning, avoid combining multiple compounds with overlapping sedating, stimulating, serotonergic, blood-pressure, anticoagulant, or liver-metabolism effects unless a qualified clinician has reviewed the context.
