Redcon1 | Double Tap

Redcon1 Double Tap is a fully disclosed stimulant-based thermogenic built around one clear strategy: create a noticeable increase in energy, motivation, and calorie-burning support without relying on a single oversized caffeine hit. Instead of making caffeine do all the work, the formula spreads the workload across multiple methylxanthines and purine alkaloids, then adds acetyl L-carnitine and green tea extract to support energy metabolism and fat-loss adherence. That matters, because the best fat burner is rarely the one with the most aggressive label. It is the one you can actually use consistently while training hard and dieting.

The backbone of the formula is its stimulant system. Caffeine anhydrous is included at 150mg for a fast, familiar onset. This is the part you feel first: greater alertness, improved training readiness, and stronger perceived energy. It is then paired with 1,000mg di-caffeine malate, which contributes to the product’s verified 261mg total caffeine while slowing the delivery profile compared with anhydrous alone. In practical terms, this reduces the “all at once” spike-and-drop effect common to cheaper thermogenics that are basically just caffeine dressed up with label noise.

TeaCrine® provides 100mg theacrine, which sits directly in the clinically relevant range of 100–300mg. Mechanistically, theacrine acts as a dual-action neuromodulator: it antagonizes adenosine receptors to delay fatigue while also influencing dopamine signaling through D1 and D2 pathways to support motivation, mood, and focus. This is one of the most intelligent parts of the formula. TeaCrine® is not just there to add another stimulant name to the label; it is there because the best evidence for theacrine is in combination with caffeine, where it helps extend subjective energy and focus with less dependence on simply escalating caffeine dose.

Theobromine is included at 100mg. That is below the more commonly studied 250–500mg standalone range, so this is not a fully clinical theobromine dose on its own. But it is still a purposeful inclusion. Theobromine is another methylxanthine that antagonizes adenosine receptors and inhibits phosphodiesterase, helping preserve cAMP while promoting smoother vasodilation and bronchodilation. In a multi-stimulant system, 100mg can still contribute to a more open, steady, less abrupt feel to the energy profile.

Acetyl L-carnitine HCl at 1,000mg is one of the formula’s more underrated pieces. Unlike plain L-carnitine chosen purely for label recognition, acetylated carnitine crosses the blood-brain barrier more effectively and is often used where both cognitive support and fatty acid transport are relevant. In the gym, that can translate to better mental drive and a more “on” training state, especially during low-calorie phases. Green tea leaf extract at 500mg reinforces the thermogenic side of the formula through catechin content and its established synergy with caffeine in fat-loss research, particularly around energy expenditure and adherence during dieting.

As a system, Double Tap makes sense. Fast-acting caffeine initiates the effect, di-caffeine malate extends it, TeaCrine® supports motivation and helps reduce the flatness that can come with stimulant habituation, theobromine smooths the ride, and green tea plus acetyl L-carnitine give the formula a true weight-management identity rather than making it just another pre-workout in disguise.

Transparency is a genuine positive here. There is no proprietary blend hiding stimulant totals or underdosed actives. Every key ingredient and dose is disclosed, which is still better than much of the fat-burner category. On day 1, expect a clear rise in alertness, better appetite discipline, and a stronger willingness to train or move. Over 2–4 weeks of consistent use alongside a calorie deficit and training plan, the value is less about a dramatic new sensation and more about repeatable output: better workout consistency, easier adherence, and a smoother daily energy profile than single-source caffeine products usually deliver.
