Why This Combo

Pre and post-workout protein each do different jobs:

You can do the same with one whey, but you'll either feel heavy pre-workout or under-fed post-workout. Two specialized products solve both.

Total Monthly Cost

Math based on 4 training sessions per week (16 sessions per month) with one pre and one post-workout shake each:

Monthly cost math
Pre-workout clear whey: Clear Whey Isolate (16 servings/mo)$12.80/mo
Post-workout isolate: ISO100 Hydrolyzed Whey (16 servings/mo)$14.65/mo
Total monthly cost$27.44

That's about $27/month for around 720g of training-window protein, or roughly $2.50 per training day.

How to Use Each

MyProtein Clear Whey (pre-workout)

One scoop in 16 oz cold water, 30 to 60 minutes before training. The juice-like texture goes down fast, sits light, and gives you a steady release of amino acids during the session. Don't drink it 5 minutes before stepping under a heavy bar: even clear whey can cause reflux if you swallow and squat too close together.

Dymatize ISO100 (post-workout)

One scoop in 8 oz water within 30 minutes of finishing your last set. Hydrolyzed isolate doesn't need milk to absorb fast: water is fine. If you train fasted in the morning, double the dose to 2 scoops (50g) to compensate for the longer post-meal gap.

Frequently Asked Questions

Do I actually need protein before training?

If you've eaten a high-protein meal within three hours of training, no. If you train fasted or your last meal was protein-light, a 20g pre-workout shake measurably improves session recovery. It's not magic; it's just amino acid availability.

Can one whey cover both windows?

Yes, if you're okay with the trade-off. A regular whey blend works for both, but most lifters find traditional milky whey too heavy to drink 30 minutes before a heavy session. Splitting into two products feels better and adds little cost.

How long is the post-workout window really?

Older research said 30 minutes. Newer research (Aragon and Schoenfeld, 2013) shows the anabolic window extends to 4 to 6 hours, especially if you ate a high-protein pre-workout meal. Practically: aim for protein within 60 minutes post-workout, but don't panic if life pushes you to 90.

Is hydrolyzed whey actually faster than isolate?

Modestly. Hydrolyzed whey is pre-broken-down, which speeds digestion by around 20 to 30%. Standard isolate hits peak blood amino acids in 60 to 90 minutes, hydrolyzed in 45 to 60. For the post-workout window, hydrolyzed has a slight edge.

Can I skip clear whey and just chug a sports drink?

Not if you want pre-workout protein. Sports drinks have carbs and electrolytes but no protein. Clear whey delivers 20g of protein in the same juice-like texture, which is the actual point of having it pre-workout.

What if I train twice a day?

Add one extra ISO100 shake between sessions. Two training sessions in a day means roughly double the training-window protein demand. Adding 25g of fast protein at midday closes the gap without overcomplicating the stack.
