Gear + Companions
Editorial picks only — every product on this page is chosen for a specific reason we explain on each card. Reconstitution gear, research- backed supplement companions, and framework reading. We earn a commission through Amazon on the click; it never influences what we recommend.

Reconstitution Gear
BAC water, syringes, swabs — the kit every injectable protocol needs
Alcohol Prep Pads (Sterile, 200 count)
Dynarex
Standard 70% isopropyl sterile pads. Use one per vial stopper + one per injection site. Individually wrapped so you can toss a few in a travel kit.
Bacteriostatic Water 30mL (0.9% Benzyl Alcohol)
Empower Pharmacy / generic medical supply
The universal solvent for reconstituting every lyophilized peptide on our catalog. Benzyl-alcohol preservative keeps reconstituted vials viable for 28 days refrigerated. One 30mL bottle reconstitutes roughly 15–30 peptide vials.
Insulin Syringes 29G × 1/2" × 1mL (100 count)
EasyTouch
Wider 1mL barrel for higher-dose protocols (0.3mL+) — e.g. BPC-157 5mg vial reconstituted with 1mL BAC, 0.2mL per 1mg dose. 29G is still subcutaneous-friendly.
Insulin Syringes 31G × 5/16" × 0.5mL (100 count)
EasyTouch
Thinnest-gauge standard insulin syringes — 31G is the sweet spot for subcutaneous injection comfort. 0.5mL barrel graduates cleanly for sub-0.25mL doses (most peptide protocols fall here).
Storage + Disposal
Mini fridges and sharps containers — protocol-grade, not household
1-Quart Sharps Disposal Container
BD / Becton Dickinson
FDA-cleared sharps container. One 1-quart holds a few months of peptide research disposables for most protocols. Don't improvise with household plastic — pharmacies reject it for takeback.
Mini Skincare Fridge 4L (12V / 110V)
Cooluli
Reconstituted peptides live 28 days refrigerated (0–8°C). A dedicated mini-fridge keeps them separate from food + stays at a stable temp. 4L is enough for 20+ vials with room for BAC water.
Metabolic Companions
Targeted at GLP-1 side effects — electrolytes, fiber, protein floor
LMNT Electrolyte Drink Mix Variety Pack (30 sticks)
LMNT
GLP-1-class peptides suppress thirst as a side effect — dehydration + electrolyte drop is the #1 reason people feel like garbage on Tirzepatide or Semaglutide. LMNT's 1000mg sodium + 200mg potassium formula targets that exact gap.
Psyllium Husk Fiber Capsules (500 ct)
NOW Foods
Constipation is the most-reported GLP-1 side effect by a wide margin. A daily soluble-fiber dose dramatically reduces it without stopping the appetite effect. Capsules over powder for compliance — it's easier to actually take them.
Muscle Companions
Pairs with GH-axis + IGF protocols — substrate + signaling
Creatine Monohydrate Powder 1kg
BulkSupplements
Most-studied supplement in history. Pairs cleanly with GH-axis peptides (CJC-1295 / Ipamorelin / Sermorelin) because both up lean-mass signaling via different pathways. 5g/day, unflavored, cheapest per gram we've found.
Whey Protein Isolate 5 lb (Grass-Fed, Unflavored)
NAKED Nutrition
Aggressive appetite suppression on GLP-1s → protein intake craters → lean-mass loss accelerates. A flavorless isolate you can stir into anything is the lowest-friction protein floor.
Recovery Companions
For healing-axis protocols — inflammation + connective tissue
Collagen Peptides Unflavored (2 lb)
Vital Proteins
Direct substrate for connective-tissue repair. Extra leverage when stacked with BPC-157 / TB-500 — the peptides signal repair, collagen provides the raw material. Dissolves in coffee or water.
Magnesium Glycinate 400mg (240 capsules)
Nested Naturals
Glycinate form is the most-bioavailable and doesn't cause GI distress. Pairs with cognitive + sleep peptides (DSIP, Selank) and with any protocol that ramps training intensity. Roughly 80% of US adults are sub-optimal in Mg.
Omega-3 Fish Oil (Molecularly Distilled, 240 softgels)
Nordic Naturals
EPA/DHA downregulates systemic inflammation — synergistic with any healing-axis peptide (BPC-157 / TB-500 / KPV). Molecularly distilled = no heavy metals. Nordic's the quality benchmark.
Cognitive Companions
Stacks with Semax, Selank, Cerebrolysin, and the P21 family
Alpha-GPC 600mg (60 capsules)
Double Wood
Choline donor — raw material for acetylcholine synthesis. Stacks cleanly with cognitive peptides (Semax, Selank, Cerebrolysin) that upregulate neurotransmitter signaling. 600mg is the studied dose range.
Lion's Mane Mushroom Extract (120 capsules, 2g/serving)
Host Defense / Paul Stamets
Hericium erinaceus — the one mushroom with direct NGF + BDNF evidence in human trials. Long-game neuroprotection, pairs thematically with Cerebrolysin / P21 protocols.
Longevity Companions
NAD+ precursors + sirtuin activators — NAD+/Epithalon stacks
NMN (Nicotinamide Mononucleotide) 500mg × 60 caps
Double Wood
Oral NAD+ precursor — the natural stack-mate for injectable NAD+ protocols (cheaper, daily use) + longevity peptides like Epithalon. 500mg/cap hits the high end of studied ranges.
Trans-Resveratrol 500mg (120 capsules)
Double Wood
Sirtuin-activating polyphenol — activates SIRT1 alongside NAD+ stacks (NAD+ is the cofactor sirtuins need to fire). Always trans- isomer; cis- is inactive.
Sleep Companions
Pairs with DSIP + Epithalon protocols
Glycine Powder 1kg (Pharmaceutical Grade)
BulkSupplements
3g pre-sleep lowers core body temp + shortens sleep latency in studies. Pairs naturally with DSIP (delta-sleep-inducing peptide). Unflavored powder dissolves cold; bulk is cheapest.
Sexual / Circulation
Central + peripheral NO signaling — complements PT-141
L-Citrulline Malate 1kg Unflavored Powder
BulkSupplements
Raises systemic NO more effectively than L-arginine (better GI tolerance + longer half-life). Pairs with PT-141 where one works centrally (brain) and the other peripherally (vasculature).
Skin Companions
Topicals that layer safely with GHK-Cu research
Granactive Retinoid 2% Emulsion (30mL)
The Ordinary
Modern retinoid with the efficacy of tretinoin without the irritation. Layers safely with GHK-Cu topical research protocols (retinoid evenings, GHK-Cu mornings). Under $15 is the best skincare value on Amazon, full stop.
Further Reading
Framework + clinical references for serious study
Outlive: The Science & Art of Longevity (Peter Attia MD)
Peter Attia
Framework reading for why longevity protocols (NAD+, Epithalon, MOTS-c direction) matter mechanically. Attia's exercise + metabolic health chapters alone justify the shelf space.
The Peptide Protocols (Book 1): William A. Seeds MD
Dr. William Seeds
The clinical peptide-therapy reference. Seeds was training physicians on peptide protocols before most of the space existed. Not sensational, not hype — clinical.
