Best Peptide Stacks

Purpose-built combinations for specific goals. Each stack explains what to take, why they work together, and exactly how to run them.

Most Popular
The Fat Destroyer Stack
Maximum fat loss with appetite suppression, metabolic boost, and targeted lipolysis. The GLP-1 does the heavy lifting while HGH Frag attacks stubborn fat stores your diet can't reach.

Why These Work Together

Retatrutide suppresses appetite and burns fat via 3 receptor pathways. HGH Frag adds targeted lipolysis — especially for stubborn belly/love handle fat that GLP-1s alone struggle with. 5-Amino-1MQ blocks the NNMT enzyme that keeps fat cells in storage mode, shifting your metabolism to burn-first. Three completely different mechanisms that compound each other.

Timeline
Wk 1–4Retatrutide 0.5→2mg only. Let your body adjust to GLP-1 side effects before adding compounds.
Wk 5–8Titrate Reta to 4mg. Add HGH Frag 250mcg AM fasted. Add 5-Amino-1MQ 100mg daily.
Wk 9–16Reta at 6–8mg. HGH Frag 250mcg 2x/day. Continue 5-Amino. Expect visible fat loss weekly.
Wk 17–24Maintain or increase Reta. Drop HGH Frag after 12 weeks if desired. Continue 5-Amino.

Key Notes
  • Inject HGH Frag fasted — eating within 30 min kills the effect
  • GI sides from Retatrutide are worst weeks 1–4, push through
  • High protein diet (1g/lb) critical to minimize muscle loss
  • Expect 3–5 lbs/week loss during peak phase
  • Can swap Retatrutide for Tirzepatide if unavailable

Why These Work Together

Tirzepatide creates the caloric deficit and fat burn. CJC-1295 + Ipamorelin elevate growth hormone — which drives muscle protein synthesis and recovery even while cutting. This is key: normally you lose muscle when you lose fat. The GH stack prevents that. BPC-157 protects connective tissue that's under more stress when you're training hard in a deficit.

Timeline
Wk 1–4Tirzepatide 2.5mg. Start CJC+Ipa immediately. Add BPC-157 if training heavy.
Wk 5–8Tirz at 5mg. Body composition changes become visible. Sleep quality improves from Ipa.
Wk 9–16Tirz at 7.5–10mg. Peak recomp phase — losing fat, maintaining/gaining strength.
Wk 17–24Maintain doses. Consider dropping Tirz dose to maintain weight. Keep GH stack running.

Key Notes
  • Protein intake is critical — aim for 1g+ per pound of bodyweight
  • Inject Ipamorelin 30 min before bed on empty stomach
  • Train 4–5x/week with progressive overload
  • Bloodwork (IGF-1, hormones) at week 8 recommended
  • Can swap Tirzepatide for Semaglutide if preferred
Gold Standard
The Recovery Stack
The go-to combination for healing tendons, ligaments, muscle tears, and joint injuries. BPC handles local repair while TB-500 reduces systemic inflammation. GHK-Cu accelerates tissue remodeling.

Why These Work Together

BPC-157 grows new blood vessels directly into damaged tissue (angiogenesis). TB-500 travels systemically reducing inflammation via cytokine downregulation. GHK-Cu activates 4,000+ repair genes and accelerates collagen remodeling. Ipamorelin boosts overnight GH — the primary driver of tissue repair during sleep. Four different healing mechanisms hitting the injury simultaneously.

Timeline
Wk 1–2Loading phase: BPC 500mcg 2x/day + TB-500 5mg 2x/wk. Inflammation drops noticeably.
Wk 3–4Add GHK-Cu and Ipamorelin. TB-500 drops to 2.5mg 1x/wk maintenance.
Wk 5–8Full stack running. Majority of structural healing occurs during this phase.
Wk 9–10Taper off. Continue BPC-157 if needed. Most injuries show 70–90% recovery.

Key Notes
  • Inject BPC-157 as close to the injury as possible — not into it
  • TB-500 can be injected anywhere — it works systemically
  • Don't rush back to full training — let the tissue remodel
  • Pair with light rehab exercises for best results
  • Can run BPC-157 alone for minor issues

Why These Work Together

CJC-1295 provides a sustained GH baseline elevation all week via GHRH pathway. Ipamorelin fires sharp nightly GH pulses via the ghrelin pathway — a completely different receptor. Two pathways, maximum pulse. Tesamorelin (FDA-approved) adds targeted visceral fat reduction, the deep belly fat that ages you fastest and damages organs.

Timeline
Wk 1–2Start CJC + Ipa. Sleep quality improves first — deeper, more restorative sleep.
Wk 3–4Add Tesamorelin. Skin quality and recovery start improving.
Wk 5–12Full effects compound. Body comp changes visible. Energy and mood elevated.
Wk 13+Run 5 on / 2 off to prevent desensitization. Can run 3–6 months total.

Key Notes
  • Empty stomach for Ipamorelin — carbs/fat blunt the GH pulse
  • Run 5 days on / 2 days off to prevent pituitary desensitization
  • Bloodwork: check IGF-1 at baseline and week 8
  • First noticeable effect is usually improved sleep (week 1)

Why These Work Together

Four pillars of aging addressed simultaneously: Epithalon rebuilds telomeres. SS-31 repairs mitochondria from the inside. NAD+ restores the cellular energy currency that depletes 50%+ by age 60. FOXO4-DRI clears senescent "zombie" cells that poison surrounding tissue. Each targets a different aging mechanism — together they hit the full spectrum.

Timeline
Day 1–10Epithalon blast (10mg/day). Start NAD+ 3x/wk and SS-31 daily.
Wk 2–4Continue NAD+ and SS-31. Add FOXO4-DRI if included. Epithalon complete.
Wk 5–8Taper off all compounds. Cellular benefits continue to accumulate.

Our Story

We were the lab rats
so you don't have to be

TrustedPeptides was built out of frustration. When we first got into peptides, the information landscape was a mess — scattered Reddit threads, contradictory dosing guides, shady vendors with no testing, and zero consolidated resources that actually explained what these compounds do in plain English.

So we did what anyone obsessed enough would do: we tested them ourselves. Every peptide listed on this site has been personally used in our own research and experimentation. We've dealt with the nausea from titrating GLP-1s too fast, dialed in the exact BAC water ratios that make dosing precise, ran the recovery stacks through real injuries, and figured out which vendors actually deliver what they promise.

We built the resource we wish existed when we started — one place with honest vendor reviews, real-world protocols, and information written by people who have actually used every compound on this list.

"We spent years experimenting, researching, and learning the hard way so you can start with clarity instead of confusion. Every recommendation on this site comes from firsthand experience — not theory."

— The TrustedPeptides Team
Firsthand Experience
Every single peptide on this site has been personally used and evaluated by our team. We don't write about compounds we haven't tried. If it's listed here, we've run it, documented it, and formed an honest opinion on it.
No Vendor Bias
Our vendor rankings are based on actual orders, purity testing, and customer experience — not who pays us the most. We've ordered from every vendor on our list multiple times before recommending them.
Honest Information
We tell you what works, what doesn't, and what the side effects actually feel like. No hype, no exaggeration. If a peptide is overhyped or underwhelming, we'll say so. You deserve the truth before putting anything in your body.
Always Updating
The peptide space moves fast — new compounds, new regulations, new vendor issues. We keep this site current because outdated information in this space can be genuinely dangerous.
