Supplement when Peri-RX is out of stock

[Adam Bueltel]

I’ve been out of Peri-RX for a while, and it’s been out of stock for weeks. Anyone know of a similar brand to use in the meantime that isn’t loaded with junk and has the same components at their clinically effective doses? For now I’m just creatine and coffee

I've spent a LOT of time looking for something comparable and if it's out there I am unable to find it. The closest thing I've found is the preworkout from Nutricost:

Now granted the dosages aren't all the same as peri-Rx, its MUCH closer than 90% of the other preworkouts available on Amazon. It also has several other ingredients not in periRx, which you may consider a plus or a minus.

Comparison
PeriRX
8 grams of citrulline malate
5 grams of creatine monohydrate
6.4 grams of beta alanine
Beet root concentrate to yield 500mg nitrates and 12.5mg betalains
300mg caffeine anhydrous

Nutricost
6 grams of citrulline malate
0 grams of creatine monohydrate
3 grams of beta alanine
No Beet root concentrate to yield 500mg nitrates
300mg caffeine anhydrous

You'd need to get creatine elsewhere. And you'd miss out on the beets.

I can't vouch for it, I wasn't convinced enough to buy it. I'm sticking to caffeine gum for a preworkout.

You can sort of make your own, but taste is very questionable, beetroot powder is difficult to find specifics on and the cost seems to be overall the same or higher than Peri RX.
