The 1st Phorm GLP-1 Support Stack is a four-product bundle at $189.99 built on clear whey isolate, micronutrients, greens and fibre, with a 110 percent guarantee.

Overview

1st Phorm is a sports nutrition company rather than a wellness brand, and its GLP-1 Support Stack reflects that. The stack brings four products together into one daily system: Phormula-1 Clear, a clear whey protein isolate delivering 22g of protein from six ingredients with zero carbs, fat or sugar; Micro Factor, a micronutrient pack at $69.99 standalone; a greens component from the Opti-Greens 50 line; and a fibre element. The company frames it as supporting lean muscle, filling nutrient gaps and staying regular on a GLP-1.

The protein choice is the strongest part. Whey isolate provides a complete amino acid profile high in leucine, the amino acid that drives muscle protein synthesis, and muscle loss during rapid weight loss is the most serious risk GLP-1 users face. A clear format with six ingredients and no carbs, fat or sugar is also considerably easier to face than a thick shake when nausea is present, which is a practical detail most brands miss.

Pricing is $189.99 against a $220.96 regular price, and the stack carries a 4.9 out of 5 rating along with the company's 110 percent money-back guarantee. Individual components are available separately: Phormula-1 Clear at $49.99, Micro Factor at $69.99, Opti-Reds 50 at $66.99 and Full-Mega at $47.99. The caution is that 1st Phorm's wider catalogue includes thermogenic fat burners with stimulants, which are a poor fit for anyone already dealing with GLP-1 related nausea and disturbed sleep.

What Is Actually in It

Formula and Format
  • Phormula-1 Clear with 22g of whey isolate and six ingredients
  • Zero carbs, fat and sugar in the protein
  • Micro Factor for daily micronutrient coverage
  • A greens component from the Opti-Greens line
  • A fibre element for regularity
  • A 110 percent money-back guarantee

Supplement or Medication?

Dietary supplements. Nothing in the stack acts on GLP-1 or appetite. The purpose is protein, micronutrients, greens and fibre, addressing what reduced eating removes rather than the medication itself.

How You Buy It

1

Buy the stack or components

Available as a $189.99 bundle or as separate products.

2

Prioritise the protein

Phormula-1 Clear is the component with the strongest rationale.

3

Use the clear format when nauseous

A clear protein is easier to face than a thick shake.

4

Skip the thermogenics

1st Phorm's fat burners suit GLP-1 users poorly.

Who It Is Sold To

  • Adults on GLP-1 medication concerned about muscle loss
  • No consultation or clinical assessment involved
  • Whey is dairy-derived, so unsuitable for vegans
  • Not appropriate as a substitute for prescribed obesity treatment
  • Speak to a clinician about protein targets if you have kidney disease
  • The wider range includes stimulants unsuited to this population

Clinical Oversight and Evidence

Clinical Oversight

None. This is a retail sports nutrition stack with no clinical involvement. If you have kidney disease, protein intake is a clinical question rather than a preference.

Evidence

No trial on the stack. The case for adequate protein preserving lean mass during weight loss is well established in the sports nutrition literature and is the strongest single rationale in this whole category. The micronutrient and fibre components address documented gaps created by reduced intake.

Frequently Asked Questions

What is in the GLP-1 Support Stack?

Four products: Phormula-1 Clear whey isolate with 22g of protein, Micro Factor for micronutrients, a greens component from the Opti-Greens line, and a fibre element. It sells at $189.99 against a $220.96 regular price.

Why clear whey isolate?

It provides a complete amino acid profile high in leucine for muscle protein synthesis, with only six ingredients and zero carbs, fat or sugar. A clear format is also considerably easier to face than a thick shake when nausea is present.

What is the 110 percent guarantee?

1st Phorm's money-back guarantee, which is more generous than the standard refund policies most supplement companies offer.

Should I take 1st Phorm's fat burners too?

No. The wider range includes thermogenic stimulants, which suit GLP-1 users badly given the nausea and sleep disturbance already common on medication.

Can I buy the components separately?

Yes. Phormula-1 Clear is $49.99, Micro Factor is $69.99, Opti-Reds 50 is $66.99 and Full-Mega is $47.99, so buying the stack saves against the component total.

Is it suitable for vegans?

No. The protein is whey isolate, which is dairy-derived.

Is it FDA approved?

No. These are dietary supplements, so they do not require FDA approval before marketing and their claims have not been evaluated by the FDA.

Our Verdict

1st Phorm comes at this from sports nutrition rather than from wellness marketing, and it shows in the priorities. The stack leads with Phormula-1 Clear, a clear whey protein isolate delivering 22g of protein from just six ingredients with zero carbs, fat or sugar, which is exactly the right kind of protein for someone whose appetite has collapsed and who needs to protect lean mass. Around it sit Micro Factor for micronutrients, a greens powder and a fibre component, addressing the four things reduced eating takes away. At $189.99 against a $220.96 component total, with a 4.9 rating and a 110 percent money-back guarantee, the commercial terms are unusually confident. The reservations are cost and context: this is a serious monthly outlay, and the surrounding range includes thermogenic fat burners that suit GLP-1 users badly.
