"200mg caffeine for explosive energy"
200mg caffeine is within the 150-300mg range shown to improve athletic performance in dozens of trials.

"CarnoSyn Beta-Alanine for muscular endurance"
Beta-alanine at 3.2-6.4g/day improves endurance. C4's 2g dose is below optimal but not useless with daily loading.
-
"AI-Powered Peptides (PeptiPump®) for performance"
PeptiPump® has no published large-scale human clinical trials. The 'AI-designed' label describes development, not proven efficacy.
Internal: PubMed search — no peer-reviewed RCTs on PeptiPump® in humans as of 2025 -
"Huperzine A for enhanced focus"
Huperzine A accumulates in the body. Daily pre-workout use risks overexposure; experts recommend cycling, not daily dosing.

Consumer advice
C4 Original is a legitimate pre-workout that will actually do something. The 200mg caffeine is the real workhorse here — don't overthink it. If you're caffeine-sensitive, start with half a scoop. The 30% subscription discount brings it to $0.82/serving, which is reasonable for a branded product. If you want to save money, a plain caffeine pill ($0.03/dose) + bulk beta-alanine powder ($0.05/dose) does 90% of the same job for a fraction of the cost. Skip the "AI-powered peptide" hype — PeptiPump® has almost no published human trial data. Huperzine A is a real nootropic but the dose here is almost certainly too small to matter. Overall: fine product, honest-ish claims, just don't expect miracles beyond what caffeine already delivers.
