Shredder Stack Dosing Schedule: Running Reta, Tesa, and MOTS-C Together

Stacks — 2026-06-09

The Shredder Stack runs three compounds on three different cadences. Once the schedule is laid out on a calendar it's straightforward. This is the dosing reference: concentrations, unit math, and an example week you can copy.

Concentrations and Unit Math

All three vials reconstitute to the same 10 mg/mL, which keeps the math identical across the stack:

Vial	Bac water	Result	On a U-100 syringe
Reta 20mg	2 mL	10 mg/mL	10 units = 1 mg
Tesa 10mg	1 mL	10 mg/mL	10 units = 1 mg
MOTS-C 10mg	1 mL	10 mg/mL	40 units = 4 mg

Reconstitute each vial separately, refrigerate, and use within four weeks.

The Three Cadences

Reta — once weekly. Titrated: 2 mg (20 units) week 1, 3 mg (30 units) week 2, then 4 mg (40 units) from week 3 on.
Tesamorelin — nightly. 1 mg (10 units) before bed, fasted. Aggressive phase: 1.5–2 mg (15–20 units).
MOTS-C — twice weekly. 4 mg (40 units) per dose, spaced 3–4 days apart.

An Example Week (Week 3 Onward)

Day	Reta	Tesa	MOTS-C
Sun	40 units	10 units	—
Mon	—	10 units	40 units
Tue	—	10 units	—
Wed	—	10 units	—
Thu	—	10 units	40 units
Fri	—	10 units	—
Sat	—	10 units	—

Tesamorelin is the only daily injection. Reta anchors one day a week; MOTS-C lands on two.

Sustainable vs. Aggressive

Sustainable: Reta 4 mg/week, Tesa 1 mg nightly, MOTS-C 4 mg twice weekly
Aggressive body-composition phase: Tesa up to 1.5–2 mg nightly, Reta stepped to 6 mg only if results stall after 6–8 weeks

Push one variable at a time, and give each change at least two weeks before judging it.

Mapping Bundles to One Month

At the doses above, here's how long each vial actually lasts:

One Reta 20mg vial — roughly 5 weeks at titrated dosing (one vial covers a month with margin)
One Tesa 10mg vial — about 10 days at 1 mg nightly, so a full month needs three
One MOTS-C 10mg vial — about 9 days at 8 mg/week (4 mg twice weekly), so a full month needs three

That's why the Shredder Stack Complete bundles 3× Tesa and 3× MOTS-C: it's a full month of all three compounds in one purchase. The base Shredder Stack holds one vial of each — only ~10 days of Tesa and MOTS-C — so it's a short intro to the full stack, not a complete month.

The interactive version of this schedule, with reconstitution walkthroughs, lives on the Shredder Stack dosing guide.
