Verified listingAbout Hybrid Biology
What is Hybrid Biology?
Hybrid Biology is a men's health and hormone clinic at 699 Hampshire Road, Suite 101, in Westlake Village, California. Its main work is testosterone and hormone replacement, offered through a TRT clinic and an HRT clinic, with testosterone injections and hormone programs for men and women. It also lists peptide therapy, anti-aging and longevity programs, HGH protocols, sexual health care, and medical weight loss using GLP-1 medications. The medications it names are semaglutide and tirzepatide, plus the peptides BPC-157 and TB-500.
The clinic describes its care as physician-led, with each protocol starting with bloodwork. It does not name the physician who prescribes. It reports 40+ years in practice, serves Ventura County and Los Angeles County, and names Thousand Oaks and Calabasas among the areas it serves. It is rated 5 on Google from 7 reviews. The phone number is (805) 914-0279.
What does it cost?
It does not publish prices. There is no consultation fee, no monthly program price, and no price for medication. It does not say whether medication is included in any price, whether insurance is accepted, or whether it offers HSA or financing. It also does not publish membership terms or a cancellation policy. Until you call, you will not know what a first visit or a month of treatment costs.
Ask for the consultation fee first. Then ask for the full monthly cost of any program you are considering, along with a list of what that number covers.
What should you ask before you book?
Start with who signs the prescription. The clinic does not name its physician, so ask for the prescriber's name and credentials, and whether you will be seen in person or by video. Telehealth is not mentioned, so do not assume it is offered.
Next, ask whether the monthly fee includes the medication or bills it separately. For the GLP-1 medications, the peptides, and any testosterone, ask whether each one is a brand-name product or compounded, and which licensed pharmacy fills it. Its compounds are dispensed through licensed pharmacies, so ask for that pharmacy's name.
Then ask what follow-up costs: bloodwork before you start, repeat labs, and dose check-ins. Ask whether insurance is billed or HSA is accepted, and what cancelling involves, including any minimum commitment or notice period.
Who is it a good fit for?
This is a good fit if you want hormone-focused care close to Westlake Village, want bloodwork before any protocol, and are ready to pay out of pocket once you have a quoted price in writing. It is a harder call if you need prices or telehealth before you book, or if you want the prescriber's name before you pay a consultation fee.
