Every SLU-PP-332 protocol on file, 7 in all, labelled by where each number came from.
Who: Users described by competitor guides. No human dose has been tested in a trial.
Note: Mice got 25 to 50 mg/kg, far above this range. One competitor argues microgram doses are sized to fit a 5 mg vial, not drawn from any pharmacology.
Who: The range one competitor says shows up most often in user reports. No human dose has been tested in a trial.
Note: The 1 to 5 mg range is the daily total, not a per-shot amount.
Who: Self-experimenters as summarized by a competitor guide; app users log similar amounts. No human dose has been tested in a trial.
Note: Some inject into muscle instead. PeptIQ app users most often log 5 mg or more per injection (27 reports). One r/Peptides poster reported about 80 mg a day split three times, home-mixed from raw powder, alongside retatrutide.
Who: Users of vendor 50 mg tablets, as described by a competitor guide. No human dose has been tested in a trial.
Timing: Mornings, by most community oral protocols.
Note: The compound's developers report it lacks oral bioavailability, and every animal study injected it, so it is unknown how much of a swallowed dose reaches the blood. One r/PeptideGuide user pushed oral capsules from 100 mg to 500 mg a day for 3 weeks, reported fatigue and a drop in libido, and went back to 500 mcg to 1 mg.
Who: Adults following a competitor guide. No human dose has been tested in a trial.
Note: The guide starts at 5 mg and calls 10 to 25 mg the effective range without citing a source. Oral bioavailability is the open problem here too.
Who: Users of small-strength vendor capsules, per a competitor guide. No human dose has been tested in a trial.
Who: First-hand Reddit reports from users of premixed liquid drops. No human dose has been tested in a trial.
Note: One user started at 1,200 mcg a day and moved to 1,800 mcg in week 2, reporting night sweats. Another takes 3,000 mcg a day under the tongue in 3 doses. The developers report the compound lacks oral bioavailability, so how much reaches the blood is unknown.

Calculate with this peptideYour vial, your water, your dose: SLU-PP-332 in syringe units, with the math shown.Diluent: Bacteriostatic water
Water volumes sources use: 1 mL, 2 mL, 3 mL, 5 mL
Tablets and capsules need no mixing. Lab studies dissolved it in DMSO and Tween, not water, so how fully a water-mixed vial dissolves is not documented. A deepening yellow colour after mixing may mean the solution has degraded.
No validated rule exists, since there is no human half-life. Community oral users skip a missed dose rather than doubling the next one.
No human dose exists. Community injection doses run from 250 mcg to 1.5 mg a day, 1 to 5 mg a day split, up to 5 to 10 mg once daily. Oral users take 25 to 100 mg from 50 mg tablets. Mice got 25 to 50 mg/kg.
Some guides size the dose to fit a 5 mg vial (hundreds of mcg), others scale up the mouse dose by body surface area (hundreds of mg). One competitor puts the gap at roughly 1,000-fold. Neither approach has been tested in people.
A common choice is 2 mL of bacteriostatic water, giving 2.5 mg/mL; 10 units on a U-100 syringe is then 250 mcg. Guides also use 1 mL or 3 mL.
After 7 days at 50 mg/kg twice daily, sedentary mice ran about 70% longer and 45% farther than untreated mice. The effect disappeared in mice lacking muscle ERRα.
