A branded tesamorelin medicine is FDA approved for a specific use involving excess abdominal fat in adults with HIV and lipodystrophy. That approval does not establish a general healthy-aging, weight-management, or performance use. Compounded or otherwise unapproved versions are not FDA-approved products.

Common questions
What is Tesamorelin / Ipamorelin?
Tesamorelin / Ipamorelin is discussed in research and educational contexts as a named molecule or product label. Identity, purity, and studied form can differ across sources — a name match alone is not proof of the same material used in a study.
What does the evidence for Tesamorelin / Ipamorelin actually show?
Evidence for Tesamorelin / Ipamorelin ranges by question: preclinical models, early human work, or approved uses for specific indications. Mechanism findings and animal data do not automatically predict clinical benefit or safety in people.
Is Tesamorelin / Ipamorelin FDA-approved for general use?
Do not assume Tesamorelin / Ipamorelin is FDA-approved for the use you have in mind. Approvals are indication-specific. Many research peptides and compounded products are not approved drugs for consumer or athletic use.
What product-quality questions should I ask about Tesamorelin / Ipamorelin?
Ask what was tested (identity, purity, potency), who tested it, and whether the label matches the studied form. Third-party certificates, storage conditions, and supplier transparency matter more than marketing claims.
How is Tesamorelin / Ipamorelin different from similarly named products?
Blends, salts, fragments, and brand nicknames are often confused with Tesamorelin / Ipamorelin. Verify the exact molecule, dose unit, and route in any citation before treating it as evidence for a different product.

Conor McGregor’s Injury: Diagnosis, Recovery, and How Peptides Could Help | Longevity University #02
Two weeks after their last conference, Dr. Rehan and Milan are back in Las Vegas for Milan's birthday and a UFC card that ended in one of the most talked-about injuries of the year: Conor McGregor's leg buckling on his very first strike. In this episode, Dr. Rehan gives his thoughts on why he's leaning toward a full-thickness ACL tear over a meniscus injury, and what a realistic recovery timeline looks like for a fighter coming back from five years out. After that, Dr. Rehan gives the exact protocol he would put McGregor on if he does in fact need ACL surgery. From there the guys get into Paddy Pimblett's clinical finish, that fighter's brutal weight cuts, Max Holloway's night, and why "movement practice" athletes like McGregor seem to age better than everyone else. 01:35 Vegas, Milan's birthday & watching McGregor go down 02:41 The diagnosis: why it looks like a full ACL tear 07:14 Realistic recovery timeline & what surgery can't skip 09:26 Where peptides actually help before and after surgery 11:16 The full protocol Dr. Rehan would run for McGregor 13:57 Sponsor: XYRx (code LU10) 14:39 BPC-157 and TB-500 explained 17:17 The drug-testing pool problem 18:48 ACL vs. meniscus & why surgery is unavoidable 22:49 Paddy Pimblett's finish, his camp & those weight cuts 29:48 Max Holloway, the Vegas weekend & Conor's comeback odds Every week, Physician Dr. Rehan Muttalib and XYRx founder Milan Costich on the real science of male longevity: peptides, GLP-1s, training, and recovery.

Open resourceVideoPeptide & Hormone Therapies for Health, Performance & Longevity | Dr. Craig Koniver
In this episode, Dr. Craig Koniver, M.D., a board-certified physician trained at Brown University and Thomas Jefferson University, discusses the therapeutic application of peptides and hormones for enhancing physical and mental health and performance. We explore GLP-1 analogs for weight loss, BPC-157 for wound healing and reducing inflammation, as well as peptides that increase growth hormone, improve REM sleep, and enhance cognitive function. We also cover testosterone therapy, NAD, NMN, and NR supplementation, methylene blue for mitochondrial health, stem cell therapies, and supplements such as CoEnzyme Q10 and methylated B vitamins. Additionally, we discuss effective dosages, sourcing, safety considerations, and the importance of working with knowledgeable physicians. Whether you're currently using peptides or exogenous hormones, or simply curious about their potential benefits and risks, this episode provides the scientific rationale behind how peptides function, their potential to enhance mental and physical health, and how they can optimize performance.
