Testosterone is at its daily peak.

THE DIFFERENCE

AM looks nothing
like PM.

AM STACK — 7–10 AM

Testosterone is at its daily peak.

Zinc bisglycinate30mg
Vitamin D34000 IU
Tongkat Ali (LJ100)200mg
Omega-3 (EPA+DHA)2g

PM STACK — 8–10 PM

Cortisol falls. Recovery begins.

Magnesium glycinate400mg
Ashwagandha (KSM-66)600mg
L-Theanine200mg
Phosphatidylserine400mg

Both packs from the same subscription. The AM/PM split delivers each ingredient at its optimal biological window.

THE SCIENCE

Testosterone runs
on a clock.

Free testosterone is 20–25% higher in the AM than PM. Cortisol peaks 30 minutes after waking, then falls through the day. Recovery — where testosterone actually gets synthesized — happens during sleep.

6–10 AM

Testosterone peaks

Leydig cells in the testes produce the most testosterone in the morning. AM stack compounds support this production window directly.

6–8 AM

Cortisol awakening response

Cortisol spikes 50-100% above baseline within 30 minutes of waking. Useful for energy — but it competes with testosterone for the same precursor (pregnenolone).

10 PM – 2 AM

Recovery and synthesis

Overnight growth hormone and testosterone synthesis both require low cortisol and deep sleep. PM stack compounds work with this window.
