U-100 · 100 units = 1 mL

Know exactly where the plunger goes.

Mixing a vial and working out a dose is easy math to get wrong. This site does it for you, shows every step, and draws the answer on a syringe with real U-100 markings. The library covers 43 compounds and is honest about how much evidence sits behind each one.

Where to start

If you already know which compound you are using, go straight to the calculator. If you are still working that out, the quiz will narrow it down and show you how it got there.

Tool 01Reconstitution and dose calculator
  • Tell it your vial strength and how much bacteriostatic water you added. It gives you the concentration, the volume to draw, and the exact mark on the barrel.
  • Or work backward: pick the mark you want to draw to, and it tells you how much water to mix in.
  • It warns you if the draw would overflow the syringe, if the dose falls outside the usual range, or if you have put too much water in the vial.
  • It also tells you how many doses are left and how many days that lasts at your schedule.

Tool 02Find a starting point
  • 9 questions about your goals, your experience, how you feel about needles, and how long you want to run something.
  • Three of them are a medical screen. Anything that clashes with your answers is taken out of the results entirely rather than quietly pushed down the list.
  • You get a shortlist of 3, ranked, with the reason each one made it.
  • And if nothing here is a good fit for you, it says so.

43 compounds, and how much we actually know about each

Every entry says in plain language how much research sits behind it, and links out to the sources. The dose ranges describe what people commonly run. Whether any of it is right for you is a conversation to have with your doctor.

12 of the 43 are taken by mouth or another route that never involves a needle, so the calculator leaves them out instead of printing a mixing recipe for a capsule.

“Triple GIP/GLP-1/glucagon receptor agonist. Phase 2 randomized human trials in obesity and type 2 diabetes used 1, 4, 8 and 12 mg once weekly with 4-week step-ups, and phase 3 is ongoing. It is investigational and NOT approved by any regulator, so there is no approved label, no long-term safety data, and no pharmacy-grade product. The glucagon arm adds a heart-rate signal that semaglutide and tirzepatide do not have to the same degree.”
RetatrutideEvidence note
“Extensive animal data on tendon, ligament and gut healing. Human trial data is limited and it is not an approved medicine in the US.”
BPC-157Evidence note
“The anti-inflammatory tripeptide tail of alpha-MSH. Evidence is animal and cell-culture only, mainly rodent colitis models and in-vitro work on NF-kB signaling. There are no controlled human dosing trials, so the 200-500 mcg daily figures are compounding-pharmacy and community convention, not trial data.”

Each compound is scored for how strongly it targets each goal. The number beside each goal is how many entries claim any effect at all, which is not the same as how many are proven to work.

Multi-compound stacks, written out in full

These are the combinations people actually run. Each one lists the dose for every compound in it, the range it is usually run at, how long a cycle lasts, and the cautions that come with putting them together.

KLOW4 compounds8 weeksintermediateA fixed four-peptide healing blend sold in a single vial: GHK-Cu, BPC-157, TB-500 and KPV. It is the older GLOW blend (GHK-Cu + BPC-157 + TB-500) with KPV added, which is where the leading K comes from. Run as one daily subcutaneous shot for soft-tissue repair, gut and skin work.GLOW 423 compounds4 weeksintermediateA fixed three-peptide repair and skin blend sold in a single 42 mg vial: GHK-Cu, BPC-157 and TB-500. This is the original GLOW blend, and it is exactly KLOW with the KPV left out - KLOW is GLOW plus KPV, which is where the leading K in KLOW comes from. Run as one daily subcutaneous shot for skin, soft tissue and connective tissue work.Wolverine Stack2 compounds8 weeksbeginnerThe classic two-peptide repair stack: BPC-157 daily for local tendon, ligament and gut healing, plus TB-500 loaded twice weekly for systemic cell migration and tissue remodeling. The most commonly run injury protocol and the base that KLOW was built on top of.Retatrutide + KLOW5 compounds16 weeksadvancedA fat-loss block that pairs weekly retatrutide with the daily KLOW healing blend. The logic people give is that aggressive weight loss is catabolic and hard on skin, joints and gut, and KLOW is meant to offset that. Retatrutide does the fat loss; KLOW does nothing for it.GH Pulse (Ipamorelin + CJC-1295 no-DAC)2 compounds12 weeksbeginnerThe standard growth hormone secretagogue pairing: a GHRH analogue (CJC-1295 without DAC, also sold as Mod GRF 1-29) plus a ghrelin receptor agonist (ipamorelin), injected together so the two mechanisms produce a larger pulse than either alone. Both are short-acting, which is the point - it mimics a natural pulse instead of flattening it.Semax + Selank2 compounds4 weeksbeginnerTwo intranasal Russian-developed peptides run together as a short course: semax for focus, drive and BDNF signaling, selank as the anxiolytic counterweight that takes the edge off semax without sedation. Both are non-injectable, which is most of their appeal.Retatrutide + GH Pulse3 compounds16 weeksadvancedWeekly retatrutide for the fat loss, plus the standard nightly GHRH + GHRP pulse (CJC-1295 without DAC and ipamorelin) bolted on. The stated reason is preserving lean mass through an aggressive incretin cut. Read the evidence note before you buy that reason - the lean-mass problem is real and measured, but this specific fix is not.Tirzepatide + Tesamorelin2 compounds26 weeksadvancedThe same idea as Retatrutide + GH Pulse, built from the two compounds in their classes that actually have FDA labels: weekly tirzepatide for the weight loss, daily tesamorelin for visceral fat and the GH axis. It is the conservative version of the muscle-sparing stack - better documented on both sides, more expensive, and with a clearer glucose problem to watch.Focus Nasal (Semax + Selank)2 compounds4 weeksbeginnerSemax and selank in a single pre-mixed nasal spray, run as a short course: semax for focus and drive, selank as the anxiolytic counterweight that takes the edge off it. This is the same two compounds as the Semax + Selank entry in this library - the difference is the delivery format, not the pharmacology. It is here because the nasal route is the point: these two are formulated intranasally on purpose, and it is the one stack in this library that involves no needles at all.Sleep Nasal (DSIP + Epitalon)2 compounds2 weeksintermediateDSIP and epitalon run together on a short evening course, sold as a sleep stack and increasingly as a nasal spray. Both names promise more than the data delivers: DSIP is named after how it was discovered, not after a demonstrated hypnotic effect, and epitalon's sleep and longevity claims come almost entirely from one unreplicated Russian group. This entry exists to describe the stack accurately, not to recommend it.Energy / Immunity (NAD+ + Glutathione + Methyl-B12)3 compounds8 weeksbeginnerThe three things that end up in almost every "energy and immunity" product: NAD+ for mitochondrial redox, glutathione as the headline antioxidant, and methylcobalamin because B12 is what people associate with energy. They are combined because they are convenient to sell together, not because anyone has shown the three work better in combination than separately.Advanced Mitochondrial (MOTS-c + SS-31)2 compounds8 weeksadvancedThe two most talked-about mitochondrial peptides run together: MOTS-c, a mitochondrially encoded peptide that activates AMPK, and SS-31 (elamipretide), a tetrapeptide that binds cardiolipin on the inner mitochondrial membrane. Two different points of attack on the same organelle, which is the whole rationale. Graded advanced because both are thin on human data and because nothing you can measure will tell you whether it worked.

Guides

Before your first injection

Three short guides on mixing a vial, storing it, and picking where the needle goes.

ReconstitutionHow much bacteriostatic water to add, what strength that leaves you with, and why the same 5 mg vial can come out at 10 units or 50 depending on how you mix it.Injection sitesWhere subcutaneous and intramuscular shots go, and how to move around so you are not using the same square inch of skin every day.StorageFridge or freezer, before mixing and after, and how long a vial is good for once there is water in it.

Every dose on this site describes what people commonly do. Where a published source exists, we cite it. Where one does not, we say so and call the number convention rather than evidence. None of it is a recommendation, and several compounds here have never finished a published human trial.
