Dosing Guides
Peptide Dosing Guides
How much, how often, and for how long — for every peptide the store carries, in plain language. Each guide gives the amounts most commonly reported across published research, FDA labels where a drug version exists, and the wider peptide community, with the range, the syringe math, and the sources.
Consensus first. Each guide leads with the number most sources agree on, then shows the range.
Syringe math included. Every dose is converted to units on a standard U-100 insulin syringe.
Evidence stated. Whether the figures come from human trials, animal studies or community convention.
BPC-157
Tissue repair
The most common daily-injection peptide for tendon, ligament and gut recovery.
- Typical dose
- 250–500 mcg per injection (500 mcg/day is the most-cited total)
- How often
- Once a day, or split into two (morning and evening)
- How long
- 4–8 weeks, then a 2–4 week break
TB-500
Tissue repair
A twice-a-week peptide with a loading phase, dosed in milligrams rather than micrograms.
- Typical dose
- 2–2.5 mg per injection (2.5 mg is the most-cited figure)
- How often
- Twice a week while loading, then once a week
- How long
- 4–6 week loading phase, then 6–12 weeks maintenance; 4+ weeks off
GHK-Cu
Skin & hair
A daily 1–2 mg copper peptide, cycled because copper adds up.
- Typical dose
- 1–2 mg per injection (start at 1 mg/day, work up to 2 mg)
- How often
- Once a day; 5 days on / 2 off and 3× a week are common alternatives
- How long
- 4–8 weeks on, 2–4 weeks off
Semaglutide
Weight & metabolic
A once-a-week injection with a fixed four-week step-up schedule set by the FDA label.
- Typical dose
- Start 0.25 mg weekly; maintenance 2.4 mg weekly (1.7 mg alternative)
- How often
- Once a week, same day each week
- How long
- Continuous; each step lasts 4 weeks; 16 weeks to reach full dose
Tirzepatide
Weight & metabolic
Weekly, stepping up 2.5 mg at a time, with 5–15 mg the maintenance zone.
- Typical dose
- Start 2.5 mg weekly; maintenance 5, 10 or 15 mg weekly (15 mg max)
- How often
- Once a week, same day each week
- How long
- Continuous; at least 4 weeks on each step
Retatrutide
Weight & metabolic
Not yet approved — dosing follows the clinical-trial schedules, starting low and climbing every four weeks.
- Typical dose
- Start 1–2 mg weekly; trial doses 4, 8–9 and 12 mg weekly (12 mg max studied)
- How often
- Once a week, same day each week
- How long
- Continuous; 4 weeks per step is the trial pattern
Tesamorelin
GH axis
An approved growth-hormone releaser: 2 mg a day on the label, 1–2 mg in community use.
- Typical dose
- 2 mg per day (label); 1–2 mg in community use
- How often
- Once a day; some use 5 days on / 2 off
- How long
- Continuous on the label (26–52 weeks in trials); 8–12 week courses in community use
MOTS-c
Energy & longevity
A high-milligram, few-times-a-week peptide — a 10 mg vial is only two doses.
- Typical dose
- 5 mg per injection (range 2.5–10 mg)
- How often
- 2–3 times a week; once a week for maintenance
- How long
- 4–8 weeks on, a similar period off; 2–3 courses a year
NAD+
Energy & longevity
50–100 mg under the skin, a few times a week, injected slowly because it stings.
- Typical dose
- 50–100 mg per injection (start at 25–50 mg)
- How often
- 2–3 times a week, or daily / every other day
- How long
- 8–12 week course, then a lighter maintenance schedule; no strict cycling
BB (BPC-157 + TB-500)
Blends
The Wolverine stack in one vial — dosed by the BPC-157 number, with TB-500 riding along 1:1.
- Typical dose
- 1 mg of blend per injection = 500 mcg BPC-157 + 500 mcg TB-500
- How often
- Once a day; some use 5 days on / 2 off
- How long
- 6–12 weeks (8–12 most cited), then 2–4 weeks off
GLOW (GHK-Cu + BPC-157 + TB-500)
Blends
A skin-and-recovery blend dosed to the copper peptide: 10 units a day is the standard.
- Typical dose
- 10 units/day at the 3 mL mix ≈ 2.33 mg blend = 1.67 mg GHK-Cu + 333 mcg BPC-157 + 333 mcg TB-500
- How often
- Once a day, or Monday–Friday
- How long
- 4–6 weeks on (one vial ≈ one cycle), 2–4 weeks off
KLOW (GLOW + KPV)
Blends
GLOW with KPV added — dosed the same way, with 10–15 units a day the standard range.
- Typical dose
- 10–15 units/day at the 3 mL mix ≈ 2.67–4 mg blend = 1.67–2.5 mg GHK-Cu + 333–500 mcg each of BPC-157, TB-500 and KPV
- How often
- Once a day
- How long
- 8–12 weeks, then 3–6 weeks off (4 weeks most common)
