New products from Antaeus Labs and Prototype Nutrition

Antaeus Labs – best known for their innovative designer steroid products Trenazone, Ultradrol, and Mechabol – have just released their new stimulant product Axon.

Meanwhile Patrick Arnold’s benchtop brand Prototype Nutrition are preparing to add two new sprays to their already bulging topical lineup: A DHEA spray, and a pregnenolone spray will be joining their existing offerings of resveratrol, 7-keto DHEA/beta-androstenetriol, and 11-ketotestosterone sprays in the near future.

Antaeus Labs’ new stim is based on an extract of the plant Hedera Helix; the active triterpene Hederagenin has recently been found to be a non-selective reuptake inhibitor. [1]


Unlike “SSRIs”, the anti-depressant medications intended to specifically inhibit the reuptake of serotonin, the naturally-occurring active ingredient in Axon hederagenin also inhibits the reuptake of several other monoamines, leading to increased levels of serotonin, dopamine, and norepinephrine (noradrenaline). This is intended to cause increased metabolism, energy levels, improved mood, and heightened focus – all useful things in the sporting or weightlifting environment.


Pregnenolone, the active in Prototype Nutrition’s new topical, is not only the “prohormone” to all endogenous steroids, it’s also a potent neurosteroid. Although much of what is produced testicularly will be transformed into other endogenous compounds before reaching circulation, a topical delivery system should ensure pharmocologically relevant doses of the natural steroid that is believed to be important for cognitive function, memory, and sleep.
