Bottom line
"Fountain of Youth," "Fountain of Youth Blend/Stack," and "FOY" are marketing labels used for incompatible products. Observed sellers describe either a four-component GHK-Cu + BPC-157 + TB-500 + Epitalon mixture or a two-component Epitalon + GHK-Cu variant. No published study of either named formulation was identified.
No established or recommended human dose. Reported amounts below are market observations, not guidance.
Name and formulation variability
| Observed source/date | Claimed components | Claimed amounts | Verification limits |
|---|---|---|---|
| Spectrum 4 Medical and HLC Wellness (2026) | GHK-Cu, BPC-157, TB-500, Epitalon | 50 / 10 / 10 / 10 mg | Clinic or vendor-declared market observation; contents not independently verified |
| Elevation Wellness (2026) | GHK-Cu, BPC-157, TB-500, Epitalon | Amounts not consistently published | Clinic marketing observation |
| Intra-V (2026) | Epitalon, GHK-Cu | Two-component variant; amounts not consistently published | Same family of names applied to a materially different component set |
The name does not identify whether a listing contains two or four components. "Stack" may also describe separately supplied products rather than one co-formulated vial.
Component evidence
| Component | Separate evidence | Evidence for combination | Compatibility/stability evidence |
|---|---|---|---|
| GHK-Cu | See component monograph; the copper complex requires separate identity scrutiny | None identified for either named variant | None identified |
| BPC-157 | See component monograph | None identified for the four-component variant | None identified |
| TB-500 | See component monograph; identity ambiguity is material | None identified for the four-component variant | None identified |
| Epitalon | See component monograph | None identified for either named variant | None identified |
Combination-specific studies
No published peer-reviewed study of a product named "Fountain of Youth" or "FOY" with either observed component set was identified. The supplied sources document marketing, not efficacy.
Safety and interaction uncertainties
Two- versus four-component ambiguity prevents the name alone from identifying exposure.
No combination-specific human safety, interaction, pharmacokinetic, or toxicology data were identified.
GHK-Cu is a metal complex, adding composition and analytical questions not captured by total mass alone.
Co-formulation identity, sterility, purity, and stability cannot be inferred from a seller or clinic page.
Regulatory and product-quality notes
"Fountain of Youth" and "FOY" are not regulatory or pharmacopoeial formulation names.
The cited commercial pages are low-quality evidence suitable only for documenting market usage.
Marketing a component set does not establish that the combination is approved, safe, or suitable for humans.
Evidence gaps
No standard component definition
No combination-specific controlled study
No published co-formulation compatibility or stability data
No independent verification of the observed listings
