BioTE vs EvexiPEL vs SottoPelle: Which Pellet System Is Right for You?

If you’ve been researching pellet therapy, you’ve likely encountered BioTE, EvexiPEL, and SottoPelle — the three largest pellet systems in the US. Each has certified thousands of providers. Each claims superior outcomes. Knowing what actually differs between them will help you ask better questions when evaluating a provider.

The Core Difference: Philosophy, Not Hormones

All three systems use bioidentical testosterone and estradiol pellets made from the same plant-derived raw materials. The hormones themselves are comparable. What varies is:

• Dosing methodology — how they calculate your starting dose
• Provider training depth — what practitioners are taught and tested on
• Pellet manufacturing standards — who makes the pellets and how
• Monitoring protocols — how often levels are rechecked and how adjustments are made
• Network size and support — how much ongoing clinical guidance providers receive

Annual cost (men)	$1,000–$1,800	$900–$1,600	$900–$1,500

BioTE

BioTE is the largest pellet network in the US by provider count. Its proprietary dosing algorithm factors in weight, lab values, symptoms, and prior hormone history. The company provides extensive provider training, access to a clinical support team, and a patient-facing app for tracking labs and symptoms.

Who it’s good for: Patients who want the widest provider network (most geographic availability) and a provider who has access to ongoing clinical support from the organization.

What to consider: BioTE’s proprietary algorithm means dosing decisions are partially black-box. Some experienced BHRT practitioners outside the BioTE system criticize the formulaic approach as insufficiently individualized.

EvexiPEL

EvexiPEL is built around the dosing methodology developed by Dr. Gary Donovitz (BioTE’s founder) after he left to create the competing system. EvexiPEL emphasizes what it calls “evidence-based” dosing and places significant emphasis on mentorship — newer EvexiPEL providers are connected with experienced practitioners for case consultation.

Who it’s good for: Patients who want a provider trained in a mentorship model with more experienced oversight, particularly in the earlier stages of their practice.

What to consider: Smaller provider network than BioTE means fewer geographic options. Still a relatively young organization (founded 2014).

SottoPelle

SottoPelle traces its lineage to Dr. Gino Turek’s original pellet therapy method and is the longest-running modern pellet system in the US. Its dosing is based on the Turek formula, which many other systems are derived from. SottoPelle tends to emphasize meticulous lab monitoring — some protocols call for retesting as early as 4 weeks post-insertion.

Who it’s good for: Patients who want a system with the longest track record and detailed monitoring protocols. May appeal to those who prefer a more conservative, data-driven approach.

What to consider: Smallest provider network of the three.

What Actually Matters When Choosing

The system matters less than the individual provider. A mediocre practitioner using BioTE will get worse outcomes than an excellent independent provider using no certification system at all. When evaluating a pellet provider:

• How many pellet insertions have they performed? Experience matters more than which system they use.
• Do they retest at 6–8 weeks? Any reputable provider retests. How they respond to those results tells you about their judgment.
• Who manufactures their pellets? PCAB-accredited compounding pharmacies produce more consistent product.
• What happens if you’re over-dosed? Understanding how the provider handles adjustment problems reveals their experience level.

The best question to ask any certified provider: “Have you had patients who didn’t respond well to the standard algorithm, and how did you handle it?”
