Elk antler velvet has attracted attention in the wellness world for its unique array of naturally occurring compounds—including small amounts of Insulin-like Growth Factor 1 (IGF-1). This article explores the presence of IGF-1 in elk antler, its historical use in traditional medicine, and how it fits into modern regulatory frameworks, especially for athletes.

What Is IGF-1 and Why Is It Regulated in Competitive Sports?

IGF-1 (Insulin-like Growth Factor 1) is a naturally occurring protein in the human body, playing a key role in growth, development, and tissue repair. It is also present in trace amounts in elk antler velvet—along with a variety of amino acids, minerals, and other nutritional components.

Because IGF-1 can influence muscle recovery and growth, synthetic and recombinant forms of IGF-1—such as Increlex (mecasermin) and recombinant HGH—are listed as prohibited substances by the World Anti-Doping Agency (WADA). These forms are highly concentrated, injectable drugs that directly manipulate IGF-1 levels in the body at pharmacological doses.

"IGF-1 is prohibited both in and out of competition due to its anabolic effects."
— World Anti-Doping Agency, 2024 Prohibited List

It’s important to note that WADA does not ban elk antler velvet itself, nor do they prohibit products like Surthrival Elk Antler Velvet, which contain only naturally occurring compounds in their raw, non-synthetic form. Surthrival’s elk antler does not meet the criteria for a banned substance, and no IGF-1 is added, extracted, or modified in its formulation.

What’s in Elk Antler Velvet?

Elk antler velvet refers to the soft, nutrient-rich tissue covering the antlers during their rapid growth phase. Analysis of this material reveals a rich nutritional profile that includes:

- Naturally occurring IGF-1 and related growth factors
- Amino acids
- Collagen and structural proteins
- Calcium, magnesium, and zinc
- Glucosamine and chondroitin

This combination of nutrients supports joint, connective tissue, and overall recovery and vitality—making elk antler velvet a unique natural supplement.

Traditional Chinese Medicine (TCM) Use

Known as “Lu Rong” in Traditional Chinese Medicine (TCM), elk antler velvet has been used for over 2,000 years as a Yang tonic—supporting strength, recovery, and overall vitality.

Historically reserved for emperors and elite warriors, Lu Rong is listed among the most valued animal substances in classical Chinese pharmacopoeia.

Surthrival Elk Antler Velvet: Ethically Sourced, Naturally Effective

At Surthrival, we source our elk antler velvet from a single North American farm where we maintain direct relationships with the owner to ensure the most humane, clean, and sustainable harvesting practices available. Our product is a whole-food extract—not a synthetic drug or concentrated IGF-1 analog—making it compliant for everyday use, including by fitness and wellness enthusiasts concerned about purity and regulatory standing.

When evaluating elk antler products, it’s essential to understand the distinction between pharmaceutical-grade IGF-1 injections and natural, full-spectrum ingredients like those found in Surthrival’s formulations.
