Investigational / Not FDA Approved

BPC-157

Use the BPC-157 calculator for transparent reconstitution, concentration, mg, mcg, mL, and syringe-unit math with plain-language evidence limits.

Investigational Compound

Cagrilintide

Cagrilintide is a long-acting amylin analogue under clinical investigation, including studies involving metabolic outcomes. It is not currently an FDA-approved medicine.

FDA-Approved Ingredient for Specific Uses

HCG (Research)

Human chorionic gonadotropin (HCG) is a hormone and the active ingredient in prescription products approved for specific fertility and hormonal uses. It is not FDA approved for weight loss.

Not an FDA-Approved Drug

NAD+

Use the NAD+ calculator for transparent concentration math and learn what nicotinamide adenine dinucleotide is, why it is not a peptide, and the evidence limits.

FDA-Approved Active Ingredient

PT-141 (Bremelanotide)

Bremelanotide, often called PT-141 in research contexts, is the active ingredient in an FDA-approved prescription product for one specific indication. That approval does not cover generic research vials.

Investigational / Phase 3 Research

Retatrutide

Use the Retatrutide calculator for transparent reconstitution and concentration math, with current research context for this investigational triple agonist.

FDA-Approved Active Ingredient

Semaglutide
