The Stack
Three products covering three recovery windows: post-training, overnight, and joint support.
Hydrolyzed whey isolate absorbs faster than concentrate or standard isolate. Use this in the 30-minute post-training window when amino acid availability matters most.
See live price →Micellar casein forms a gel in the stomach and releases amino acids over six to eight hours. Drink this 30 minutes before bed.
See live price →18g of bioavailable collagen peptides for connective tissue, tendons, and joint support. Mix into morning coffee.

Different proteins do different jobs. Treating them all as interchangeable shakes leaves recovery on the table.
- Whey isolate spikes blood amino acids fast. Useful in the 30 minutes after training when muscle protein synthesis is most responsive.
- Casein keeps blood amino acids elevated overnight. An 8-hour sleep is 8 hours without dietary protein unless you supplement. Casein closes that gap.
- Collagen feeds your tendons, not just your muscles. Studies show collagen plus vitamin C 60 minutes before training increases collagen synthesis in connective tissue. Joint health is a recovery limiter most lifters ignore.
Total Monthly Cost
Math based on 30 servings of each product per month (one of each per day):
| Whey isolate: ISO100 Hydrolyzed Whey (30 servings/mo) | $27.46/mo |
| Casein: Slow-Release Casein (30 servings/mo) | $14.45/mo |
| Collagen peptides: Collagen Peptides (30 servings/mo) | $21.42/mo |
| Total monthly cost | $63.33 |
That's about $63/month for full-spectrum recovery support. Compare to a single specialty recovery shake at $4 to $5 a serving and this stack is dramatically cheaper.
How to Use Each
Dymatize ISO100 (post-workout)
One scoop in 8 oz water within 30 minutes of finishing your last set. Hydrolyzed isolate hits peak blood amino acid concentration in around 30 minutes, vs 90+ minutes for whole-food protein.
MyProtein Slow-Release Casein (bedtime)
One scoop in 8 oz milk, 30 to 60 minutes before sleep. Casein forms a slow-digesting gel that releases amino acids for six to eight hours, supporting overnight muscle repair without you waking up to eat.
Vital Proteins Collagen Peptides (morning)
One to two scoops in hot coffee, tea, or a smoothie. Collagen is unflavored and dissolves clear. If you're prepping for a tendon-heavy workout (running, jumping, deadlifting), take it 60 minutes before training with vitamin C for maximum collagen synthesis effect.
Cheaper Alternatives
- Swap ISO100 for Nutricost Whey Isolate at $28.95/2 lb. Still pure isolate, just not hydrolyzed.
- Swap MyProtein casein for Nutricost Casein at $41.79/5 lb. Same micellar form, fewer flavor options.
- Swap Vital Proteins for Sports Research Collagen at $29.99/1 lb at Costco. Single-source grass-fed, similar bioavailability.
Upgrade Path
- Upgrade ISO100 to Transparent Labs Whey Isolate for a fully-disclosed, grass-fed label.
- Upgrade casein to ON Gold Standard 100% Casein at $49.99/4 lb. The benchmark micellar casein with better taste than budget options.
- Upgrade collagen to Thorne Collagen Plus for added vitamin C, biotin, and a sport-tested formula.

Because absorption speed matters as much as protein quantity. Whey peaks fast and falls. Casein releases slowly. Collagen targets connective tissue rather than skeletal muscle. Stacking all three lets you cover each recovery window without compromise.
If your last meal is high-protein (around 40g of dairy or meat) within 90 minutes of bed, you'll get a similar slow-release effect. Casein is a tool for when life doesn't allow that schedule. If your dinner is at 6 PM and you sleep at 11 PM, a casein shake is worth it.
For joints and tendons, the evidence is reasonable. A 2017 study by Shaw et al showed 15g of gelatin + vitamin C 60 minutes before training doubled collagen synthesis in connective tissue. For skin elasticity, the evidence is weaker. For muscle building, collagen is inferior to whey: lower leucine, incomplete amino acid profile.
The 30-minute post-workout window is the practical sweet spot. Recent research has expanded the post-training window to 4 to 6 hours, but you still get peak benefit from drinking your shake within 60 minutes of finishing.
You can, but it's not optimal. Casein is best taken at bedtime to feed overnight protein synthesis. Collagen is best taken 60 minutes pre-workout (for tendon load) or in the morning (steady connective tissue support). Different timing, different jobs.
Drink the isolate post-workout as usual, then drink casein with dinner instead of right before bed. The slow-release effect still applies. You don't need two pre-bed shakes.
