"Ashwagandha lowers cortisol and stress"

"Clinically shown to increase VO2 max / endurance"
The product's own cited Luther College study found VO2 max, hemoglobin, ferritin and cortisol were similar between groups.
-
"1500mg beta-alanine boosts power and capacity"
Beta-alanine works, but performance studies use 3.2 to 6.4 grams daily. This serving delivers less than half the low end.
-
"Adaptogens improve endurance performance"
Examine's review rates rhodiola and cordyceps evidence for athletic performance as weak in humans, with mixed results.

Consumer advice
If you want the benefit that actually has good evidence here, buy plain beta-alanine — it's dirt cheap and 3-5g/day is the studied dose (this gives you 1.5g). The adaptogens might help stress and recovery, but the doses are modest and you can buy ashwagandha or rhodiola on their own for a fraction of the cost. Don't expect a race-day boost; the label itself says you need to take it for months. If you're a competitive athlete subject to drug testing, note the product isn't shown here to carry a third-party sport-certification seal — verify before use.

Is OptygenHP Premium Endurance Supplement worth the money?
OptygenHP Premium Endurance Supplement at $79.95 is questionable value. While some ingredients have merit, the formulation is overhyped. OptygenHP is an endurance supplement built on adaptogens (rhodiola, ashwagandha, cordyceps) plus a real, properly dosed hit of beta-alanine. The beta-alanine (1500mg) is legit and does what they say over time, but the "CLINICALLY SHOWN TO INCREASE ENDURANCE" headline leans on tiny, decades-old, company-friendly studies while the adaptogen doses are modest.
