Almost effortless body recomposition
Lose 10 pounds of fat without trying too hard. Bonus: Keep all your lean muscle, too. Here's how.
Back in 2005, researchers made an astounding discovery: when people took a certain plant compound for 12 weeks, they lost 10 pounds of fat as measured by DXA.
The really surprising part? They weren't dieting, and they weren't put on an exercise plan. They were instructed to just keep living their lives normally. Imagine if they'd been training and eating better.
The plant compound was called Coleus forskohlii or forskolin. It worked mainly by activating adenylate cyclase which increased cAMP levels to influence fat metabolism and hormone signaling.
Later studies showed similar benefits, but not as impressive. Why? Because forskolin is a plant, and crop strength varies. Regular forskolin is also poorly absorbed without lipids, and it can be unstable in the gut.
To solve these problems and fix consistency, Biotest invented forskolin carbonate, a pharmaceutical-grade version. As a carbonate ester, it's more lipid-soluble, crosses membranes more effectively, and is cleaved more slowly, creating a sustained release of active forskolin.
Paired with a delivery matrix (polyoxyl-8 glycerides and MCT oil), it produces a longer-lasting elevation in cAMP that drives fat mobilization, metabolic activity, and hormonal support. It turns a brief, unreliable effect into a consistent metabolic signal that impacts body composition.
We call the formula Carbolin 19 ➔ Buy at Biotest. Here are several ways to use it.
Six ways to use Carbolin-19
1. Break through fat-loss plateaus
When dieting stalls, it's often a signaling problem, not just a calorie problem. A longer-lasting cAMP signal can help "unstick" fat mobilization when your body has adapted to a deficit.
Dieting drags down metabolic rate. Carbolin-19 helps maintain intracellular signaling tied to energy expenditure, making cuts more productive and less sluggish.
3. Accelerate fat loss without increasing stimulants
cAMP tells fat cells to release stored energy. Carbolin-19 sustains that signal longer than plain forskolin, making it ideal for people who want more fat loss without piling on stimulatory thermogenics.
4. Improve nutrient partitioning
Instead of calories drifting toward fat storage, elevated cAMP helps bias the body toward using fat for fuel and directing nutrients toward muscle. This matters most when calories are at maintenance or slightly above.
5. Recomp: lose fat while maintaining or gaining muscle
This is where forskolin really shines. By supporting fat mobilization and anabolic signaling (via cAMP and downstream effects), Carbolin-19 creates a more favorable environment for body recomposition, not just weight loss.
6. Preserve muscle while using GLP-1 drugs
GLP-1s crush appetite, but they also increase the risk of losing lean mass along with fat. Carbolin-19 keeps cAMP elevated, supporting muscle protein signaling and intracellular energy, giving your body a reason to hold onto muscle while calories are low.
Whatever your goal, take two softgels of Carbolin 19 ➔ Buy at Biotest daily. It works for men and women, and it's not a stimulant.
