Provider review, September 2026

Form by GBY Review

Form by GBY prices GHK-Cu by the unit and NAD+ and glutathione by the month on single-compound pages, and answers "is this FDA-approved?" with "No" in its own FAQ. Its weight-loss figures buy a three-component formula, so neither weight-loss drug carries a scoped price.

A unit price that says it is a unit price

The copper-peptide page prints its figure as a charge per unit, not per month, while promising monthly delivery in the next sentence.

That distinction is unusual and worth crediting: a great many sellers on this roster print a bare figure and let a template supply the word "month".

The glutathione and NAD+ pages do print a monthly figure, and each is filed as one. The NAD+ figure covers an injectable, a topical and a sublingual route together, which the page names in one line.

The weight-loss price buys three things

This seller's flagship is described on its own homepage as a metabolic drug, vitamin B12 and glycine together in one compounded prescription.

All three of its weight-loss options are that formula, so no figure it publishes is scoped to semaglutide or to tirzepatide on their own.

A second bundle is described as three vials — a weight-loss drug, an advanced NAD+ preparation and glutathione — at a single monthly figure. That is a bundle price, and it is not filed against any of its parts.

Two figures for glutathione, and which one is recorded

The bundle block prints one monthly figure beside a glutathione description. The standalone glutathione page prints a much lower monthly figure.

Both were read on the same day. They are not reconciled anywhere on the site.

The standalone page is the one scoped to glutathione alone, so that is the figure on this record, and the conflict is noted rather than averaged away.

What it does and does not disclose

Each product page carries an FAQ that asks whether the compounded medicine is FDA-approved and answers no, adding that the FDA does not review compounded products for safety, effectiveness or quality.

It says medication comes from a licensed pharmacy and is delivered monthly, without naming the pharmacy.

No state list is published and no certificate of analysis is reachable. A meaningless address on this host returns a not-found response, so both are absences rather than an artefact of the host.

Who it's for

  • Readers who want a copper-peptide price with the unit it is charged against printed beside it.
  • Buyers who want each compound on its own page rather than inside one menu.
  • Shoppers who value an explicit "no" to the FDA-approval question.
  • Anyone comparing an injectable, a topical and a sublingual NAD+ route at one price.

Who should look elsewhere

  • Readers who want a scoped price for semaglutide or tirzepatide here.
  • Buyers who need a published state list.
  • Anyone who wants the dispensing pharmacy named.
  • Shoppers troubled by two unreconciled glutathione figures on one site.

Strengths

  • Gives GHK-Cu, glutathione, NAD+ and sermorelin their own pages instead of one combined menu
  • Answers "Is compounded GHK-Cu FDA-approved?" with "No" in its own FAQ, on each product page
  • Prints the unit its GHK-Cu price is charged against rather than implying a month
  • Says plainly that the FDA does not review compounded products for safety, effectiveness or quality

Trade-offs

  • Sells its weight-loss medicines only inside a three-component formula, so neither drug has a scoped price
  • Its bundle page prints a figure for glutathione that its own product page contradicts
  • Publishes no state list and names no dispensing pharmacy
  • No certificate of analysis is reachable

How we verified this

A provider to compare Form by GBY against

Trellis Vitality

Trellis Vitality frames its program around body-composition tracking rather than scale weight, pairing NAD+, glutathione and tesamorelin with at-home biomarker panels and a 90-day re-test, and names its dispensing pharmacy, VialsRX in Houston, by address.

Frequently asked questions

Why is there no semaglutide price?

Because every semaglutide figure this seller publishes buys a formula containing two other ingredients. Filing it under semaglutide would misdescribe what the money buys.

Which glutathione figure is right?

The one on the standalone glutathione page is the one scoped to glutathione alone, and that is what is recorded. The higher figure is a three-vial bundle.

Is the copper-peptide price monthly?

The page says per unit, not per month, so it is recorded as a non-monthly figure even though the same paragraph mentions monthly delivery.

Does the site claim FDA approval?

No. Its own FAQ asks the question on each product page and answers no, adding that the FDA does not review compounded products for safety, effectiveness or quality.
