Happy Mammoth Ultimate GLP-1 is a $69.99 plant-based formula claiming a GLP-1 increase of as much as 22 percent, sold by a company with 184 Better Business Bureau complaints in three years.
Overview
Happy Mammoth is a direct-to-consumer supplement company with a broad range covering hormonal, digestive and metabolic health, best known for Hormone Harmony. Ultimate GLP-1 is its entry into this category, sold at $69.99 for a single jar with bulk pricing dropping to around $44.62 a jar when buying four. The formula is plant-based and free from gluten, dairy, soy and added sugar, with GMP manufacturing stated.
The headline claim is that the ingredients in Ultimate GLP-1 were proven to raise GLP-1 levels by as much as 22 percent. That framing is worth reading carefully: it attributes the finding to the ingredients rather than to the finished product, which is a common and legally safer construction. It is also, unlike some competitors, a plausible number. Published trials on lemon flavonoids have reported GLP-1 increases of roughly 15 to 22 percent, so this is at least the right order of magnitude rather than an invented figure.
The concern lies elsewhere. The Better Business Bureau records 184 complaints against Happy Mammoth over the last three years, with some closed as unanswered by the business. That is a substantial number for any company. Trustpilot, where the brand holds around 4.2 out of 5 across roughly 12,900 reviews, shows a broadly positive picture but with a recurring theme in the negative reviews about high prices and jars that run out faster than expected. ConsumerLab has reviewed the brand's ingredient claims without testing its products.

- GMP manufacturing standards stated
- Bulk pricing that substantially reduces the per-jar cost

Supplement or Medication?
A dietary supplement. Nothing in the formula is a GLP-1 receptor agonist. The claim is that the ingredients increase your own GLP-1 secretion, which for a plant-based formula in the 22 percent range is at least mechanistically plausible even without a product-specific trial.

Clinical Oversight and Evidence
Clinical Oversight
None. This is a direct-to-consumer supplement with no clinical involvement. The absence of a trial on the finished formula means there is no product-specific data to bring to a clinician.
Evidence
No published trial on the finished product. The 22 percent claim is attributed to the ingredients rather than to the formula, which is a meaningful distinction. Published research on lemon flavonoids and related botanicals does report GLP-1 increases in that range, so the number is plausible even though it has not been demonstrated for this specific product.

How much does it cost?
$69.99 for a single jar, dropping to around $44.62 a jar when buying four.
What are the Better Business Bureau complaints about?
The BBB records 184 complaints against Happy Mammoth over three years, with some closed as unanswered by the business. Billing and refunds are the recurring themes.
What does Trustpilot say?
Around 4.2 out of 5 across roughly 12,900 reviews, which is broadly positive. The negative reviews cluster around high prices and jars running out faster than expected.

Should I subscribe?
Given the complaint history around billing, understand the cancellation terms fully before you commit, and keep records of your orders and correspondence.
Is it FDA approved?
No. It is a dietary supplement, so it does not require FDA approval before marketing and its claims have not been evaluated by the FDA.
