FLOW+

Six actives on one pathway: citrulline to arginine to nitric oxide.

FLOW+ is for the men whose numbers are fine and whose response is not. It supplies the substrate the endothelium turns into nitric oxide, protects the enzyme that does the turning, and adds dietary nitrate as a second route in. Ginseng and maca are there for the response itself; the vitamin C is there to keep the nitric oxide you make from being oxidised before it works.

What is in it

• L-Citrulline, 3000 mg
• French maritime pine bark extract, 120 mg, 65% procyanidins
• Beetroot extract, 500 mg, standardised nitrate
• Panax ginseng root extract, 400 mg, 5% ginsenosides
• Gelatinised maca root, 1000 mg
• Vitamin C, 200 mg

Ninety capsules, three a day, split between morning and evening.

What to expect

This is the fastest protocol to signal. Most men report a change in training pump and morning response inside two to four weeks. There is no blood marker to retest, so the ninety-day guarantee on FLOW+ is the plain kind: if it did nothing, tell us and we refund it.
