← All stacks🔥 Fat Loss
The Shred
Torch fat and hold your muscle — come out lean and hard, not skinny-fat and running on empty.
Why this stack works
Losing fat is easy. Losing it without ending up skinny-fat and drained is the hard part — and it's where most people wreck themselves. Crash diets and cheap GLP-1s strip your muscle right along with the fat. This stack does the opposite: it torches fat while a nightly growth-hormone pulse protects the muscle underneath, so you come out lean and solid.
The 2 — and what each does
The strongest fat-loss compound there is — the glucagon arm forces your liver to torch stored fat. ~24% loss in trials, most of it pure fat.
Wakes up your own overnight growth-hormone rhythm — strips visceral belly fat while shuttling amino acids into muscle. The engine of recomposition.
How they work together
Reta strips the fat — but on its own you'd lose muscle with it. That's exactly what the nightly GH pulse from Tesa/Ipa fixes: it protects and builds lean mass while you cut, dropping Reta's muscle loss from ~10–15% down to ≤5%. You don't just get smaller — you get lean, hard, and tight, a true 90/10 fat-to-muscle recomp.
📊 The protocol
Reconstitute2 mL BAC water per 20 mg vial → 1 mg = 10 units
DoseStart 1 mg (10 units)/wk, titrate to a 2–4 mg (20–40 units) sweet spot
FrequencyOnce weekly
TimingPM, fasted (empty stomach)
CycleRun to goal, then maintenance
Reconstitute2 mL BAC water per 5 mg + 5 mg combo vial → 1 unit = 25 mcg of each
Dose500–1000 mcg of each (20–40 units)
FrequencyDaily (many run 5 on / 2 off)
TimingPM / before bed, fasted (empty stomach)
Cycle12 weeks on / 4 off
⚡ Support the stack — run it right
🔥 Retatrutide: Keep carbs 45–55% + 1 g/lb protein; liver support (TUDCA/NAC); never stack Tirzepatide.
💪 Tesamorelin / Ipamorelin: Dose fasted (carbs blunt GH); arginine+glutamine+zinc+Mg+D3/K2; cycle.
💡 Pro tips — running this stack
▹ Add the Tesa/Ipamorelin around wk 3–4 of Reta specifically to protect muscle — it drops Reta's muscle loss from ~10–15% to ≤5% (a 90/10 fat:muscle recomp). Not optional.
▹ Dose Tesa/Ipa at night on an empty stomach — insulin (not food) kills GH, and because Reta keeps insulin flat overnight the nighttime GH pulse hits STRONGER on this combo.
▹ More Reta is NOT better — titrate from 1 mg/wk and cap fat loss at ~1%/wk. 4 mg vs 8 mg = +5% fat loss but +300% side effects. Support the liver.
▹ Keep protein >1 g/lb and lift through the whole cut — GLP-1 muscle loss is immediate; the GH pulse protects tissue but doesn't replace the protein/training floor.
