Is Deer Antler Velvet Banned in Sports? (And Does It Actually Work?)

Deer antler velvet is one of the more unusual ingredients you’ll find in an HGH releaser supplement, and it comes with a genuinely interesting backstory involving a Super Bowl scandal, a World Anti-Doping Agency statement, and a surprisingly thin body of clinical evidence. Here’s the real story, cleared of the oversimplified “banned substance” headlines that still circulate.

What Deer Antler Velvet Actually Is

Deer antler velvet is the soft, cartilage-like tissue found inside a deer or elk’s antlers while they’re still growing, harvested before the antler calcifies into hard bone. It’s been used in Traditional Chinese Medicine for centuries and is typically sold today as a powder, capsule, liquid extract, or sublingual spray ^[1]. The reason it draws attention in the HGH-supplement world is that growing antler tissue is unusually rich in growth factors, particularly insulin-like growth factor-1 (IGF-1), a hormone closely tied to how growth hormone produces its effects in the body ^[1].

The Ray Lewis Story

Deer antler velvet became a household name in early 2013, days before Super Bowl XLVII, when Sports Illustrated reported that Baltimore Ravens linebacker Ray Lewis had contacted a company called S.W.A.T.S. (Sports With Alternatives To Steroids) about a deer-antler spray while recovering from a torn triceps ^[2]. The company’s founder claimed the product delivered concentrated IGF-1 via a sublingual spray ^[3]. Lewis denied using it and was never suspended or found to have failed a drug test ^[2]. Some reports at the time claimed the practice was widespread among professional athletes, though those specific usage estimates came from media reporting rather than any official league data, and should be read with that caveat ^[4].

What’s Actually Banned, and What Isn’t

This is the part most articles get slightly wrong, so here’s the precise, current picture:

• IGF-1 itself is a prohibited substance under Section S2.4 of the WADA Prohibited List, and has been for years ^[5].
• Deer antler velvet is not itself named as a prohibited substance. WADA’s actual, repeated position is a vigilance warning: these products may contain IGF-1, and “there can be no guarantee that IGF-1 taken orally will not influence the plasma level of IGF-1, which may then influence the result of anti-doping tests” ^[5].
• The practical risk is real regardless of the technicality. The U.S. Anti-Doping Agency lists deer antler velvet alongside colostrum as natural products that can contain detectable IGF-1, and notes that while orally ingested IGF-1 would be expected to be broken down during digestion, WADA still cannot guarantee it won’t trigger a positive test ^[6].
• The NFL and other major leagues prohibit IGF-1 as a performance-enhancing substance, which is what put deer antler velvet in the spotlight in the first place ^[1].
• For U.S. military service members, deer antler velvet is not itself on the Department of Defense’s prohibited ingredients list, but products containing IGF-1 are prohibited, and there’s no reliable way to know a given product’s actual IGF-1 content without lab testing ^[7].

Bottom line if you’re a tested athlete of any kind – professional, collegiate, Olympic, or military – the “not technically banned by name” distinction won’t help you if a test comes back positive. Talk to your team physician or your sport’s anti-doping authority before using any product containing this ingredient.

Does It Actually Work?

Setting the doping question aside, the more interesting question for most readers is simpler: does deer antler velvet do anything? The clinical picture is underwhelming.

A systematic review of randomized controlled trials on velvet antler supplements found seven qualifying human trials across arthritis, sexual function, and sporting performance. Two reported some positive findings, but the reviewers judged neither convincing, while the remaining five found no effect at all ^[8]. Individual studies tell a similar story: a 10-week trial in resistance-trained men found no improvement in muscle size, strength, or performance ^[9], and a separate study measuring testosterone, IGF-1, red blood cell mass, and VO2 max directly found no meaningful hormonal or aerobic changes from supplementation ^[10].

There’s a plausible biological reason for these disappointing results: IGF-1 is a protein, and proteins are broken down into individual amino acids during normal digestion, the same issue that applies to other orally consumed hormone-containing ingredients like anterior pituitary powder (see our separate breakdown of that ingredient). Sublingual sprays are sometimes marketed as bypassing this problem, but there isn’t solid peer-reviewed human evidence confirming that claim either ^[11].

Where This Leaves You

If you’re a tested athlete, the sensible move is simple: treat any product containing deer antler velvet as a genuine doping risk, regardless of the “technically not banned by name” nuance, and check with your team or anti-doping authority first.

If you’re not subject to drug testing, deer antler velvet is a legal supplement ingredient in the U.S., and the more relevant question is the efficacy one – and on that front, the published research gives you good reason to keep your expectations modest. In a formula like GenF20 Plus, which includes it at 200 mg per serving alongside 15 other ingredients, it’s best thought of as one small piece of a broader blend rather than a meaningful driver of results on its own; see our full ingredient dose comparison for how it and the rest of the formula stack up, or our complete GenF20 Plus review for the full picture.

Frequently Asked Questions

Is deer antler velvet banned by WADA?

Not by name. WADA prohibits IGF-1 itself and has repeatedly warned that deer antler velvet products may contain detectable IGF-1, creating real risk of a positive test, but deer antler velvet is not itself on the Prohibited List.

Is deer antler velvet banned by the NFL?

IGF-1 is on the NFL’s banned substance list. Since deer antler velvet can contain IGF-1, using it carries real risk under league policy – the exact issue that made it national news during the 2013 Ray Lewis controversy.

Does deer antler velvet actually raise HGH or IGF-1 levels?

Published research is not encouraging. A systematic review of RCTs found most studies showed no measurable effect on strength, performance, or hormone levels, and IGF-1 is a protein that’s normally broken down during digestion when taken orally.

Should I worry about deer antler velvet if I’m not a tested athlete?

If you’re not subject to drug testing, it’s a legal U.S. supplement ingredient. The bigger practical question is simply whether it works, and the clinical evidence suggests modest-to-no measurable effect for most people.
