Sarsaparilla

Also known as Smilax / smilax ornata
CEVIDENCE

Plant steroids that stay plant steroids.

The honest take
Sarsaparilla is worth knowing for the myth it created. Because its saponins look like steroid hormones on paper, it has been sold for decades as a 'natural anabolic'. Human biochemistry does not perform that conversion, and no trial has found the effect. What is left is a long-used traditional tonic root with a pleasant history and a modest file — which is why it is one-thirteenth of a blend rather than a headline.
What it is
Root of a tropical climbing vine, the original flavouring of old-fashioned root beer and a fixture of nineteenth-century tonics.
How it works
Sarsaparilla contains steroidal saponins — sarsasapogenin and relatives — and this is the origin of a persistent myth. The structures resemble human steroid hormones, and the body cannot convert them into any. Plant sterols are raw material for a laboratory, not for your endocrine system.
What it does
Traditionally used as a general tonic. Present in the blend for that role.
Who it's for
Anyone taking the blend. Nobody should buy it for the steroid story.
How to use it
Daily inside PRIME's blend, with food.
What to expect
Nothing specific. It is a traditional tonic ingredient, and traditional tonics do not come with timelines.
The research
Grade C. The steroidal-saponin content is real; the claimed conversion to anabolic hormones in humans is not, and has never been demonstrated. Traditional use for general tonic purposes is genuine and long documented.

Read the labelNot a steroid, not a hormone, and not a testosterone treatment. Large amounts can upset the stomach.
