What Steroids Does CBum Take? Chris Bumstead Analyzed
What CBum Has Said About PED Use
Chris Bumstead has been notably transparent about the reality of professional bodybuilding without revealing specific details. In multiple podcast appearances and social media discussions, he has stated:
- He uses performance-enhancing drugs to compete at the professional IFBB level
- He has never claimed to be natural
- He refuses to share specific compounds or doses because he does not want fans to emulate his protocol
- He monitors his health rigorously with regular blood work
- He would retire if his health markers deteriorated significantly
- He specifically avoids trenbolone, calling it the “most toxic” steroid due to its cardiovascular and psychological side effect profile

What Is Known vs. What Is Speculated
It is important to distinguish between confirmed statements and community speculation:
| Category | Details |
|---|---|
| Confirmed (by CBum himself) | Uses PEDs; avoids trenbolone; monitors health with blood work; does not disclose specific compounds |
| Widely speculated (unconfirmed) | Testosterone as a base compound; possible growth hormone (GH) and insulin growth factor use; cutting compounds such as anavar or primobolan pre-show |
| Not confirmed, not denied | Specific doses, cycle timing, ancillary medications (AI, PCT protocol) |
Any specific “CBum cycle” or dose list circulating online is speculative. There is no verified source for this information.
What Classic Physique Bodybuilders Typically Use
Classic Physique is a weight-capped division designed to produce aesthetically proportionate physiques reminiscent of the 1970s golden era. The weight cap limits total mass relative to height, which generally means competitors use lower total doses compared to Open Bodybuilding and tend to prioritize aesthetics over raw size.
Based on bodybuilding community knowledge and published research on competitive bodybuilder drug use patterns, analysts in the community commonly speculate that Classic Physique competitors at the professional level use combinations including:
| Compound Class | Role in Classic Physique |
|---|---|
| Testosterone (e.g., enanthate, propionate) | Base compound; muscle preservation and performance; aromatization management required |
| Growth Hormone (HGH) | Lean tissue preservation, recovery, skin quality; widely suspected in elite competitors |
| Anavar (Oxandrolone) | Lean mass, strength, low androgenic side effects; popular for contest prep |
| Primobolan (Methenolone) | Quality lean gains; low estrogenic activity; aesthetics-focused compound |
| Masteron (Drostanolone) | Pre-contest hardening and definition; anti-estrogenic properties |
| Insulin-Like Growth Factor (IGF-1) | Anabolic signaling; used at elite levels |
CBum’s Health Philosophy
What distinguishes Bumstead’s public approach from many competitors is his consistent emphasis on health monitoring and longevity. He has spoken publicly about undergoing cardiac imaging, comprehensive blood panels, and working with sports physicians—practices that are not universal in competitive bodybuilding. He has stated that his goal is to compete for as long as possible while maintaining his health, not to maximize gains at any cost.
He was diagnosed with IgA nephropathy (a kidney condition) in 2018, which he has discussed openly. This condition has added a medical dimension to his health monitoring that has made blood work even more critical for him personally.
Is CBum Natural?
No. Chris Bumstead has never claimed to be natural (drug-free). He competes in the IFBB Professional League, which does not have a drug-testing policy equivalent to natural bodybuilding federations (such as the INBA or WNBF). His physique, particularly his level of muscular development combined with extremely low body fat percentages at contest time, is not achievable without PED assistance—a factual assessment consistent with the current scientific literature on natural muscle-building limits.
Frequently Asked Questions
No. Chris Bumstead has explicitly stated he will not share his specific compounds or doses to prevent fans from attempting to copy his protocol. Any “full CBum cycle” published online is speculative and unverified.
He has publicly stated he does not use trenbolone, citing its toxicity—particularly its cardiovascular and psychological side effect profile—as reasons for avoidance.
The level of muscular development and body fat percentage achieved by top Classic Physique competitors at IFBB Pro level is not achievable naturally. This is supported by published research on natural muscle-building limits and body composition ceilings.
Growth hormone use is widely speculated in the fitness community but has not been confirmed by Bumstead. HGH is commonly discussed in the context of elite-level competitive bodybuilding regardless of division.
He has publicly discussed regular comprehensive blood work, cardiac monitoring, and working with sports medicine physicians. He monitors kidney function markers closely given his IgA nephropathy diagnosis.
