BPC-157 dosage for a small / toy breed
under 22 lb (10 kg)
The short answer
For a dog weighing under 22 lb (10 kg), the dose of BPC-157 reported in the literature is 20-100 mcg per day, given once daily, over 2-4 weeks. It is studied in this weight class primarily for gastrointestinal issues, joint injury, post-surgical recovery. These figures are reported as published and are not recommendations — the dose for an individual dog must be set by a veterinarian who has examined the animal.
Worked examples at specific weights
Calculated from the reported range of 2–10 mcg per kg of body weight.
| Body weight | Calculated dose range | Frequency |
|---|---|---|
| 2 kg (4 lb) | 4–20 mcg | Once daily |
| 5 kg (11 lb) | 10–50 mcg | Once daily |
| 8 kg (18 lb) | 16–80 mcg | Once daily |
For an exact figure at your dog's weight, use the dose calculator.
Typical breeds in this weight class
Chihuahua, Yorkshire Terrier, Dachshund, Pomeranian, Shih Tzu and similarly sized dogs generally fall within under 22 lb (10 kg). Weigh your dog rather than estimating — dosing is calculated per kilogram and an estimate that is out by a few kilos changes the figure materially, particularly at the smaller end.
Common questions
How much BPC-157 for a small / toy breed?+
For a dog in the under 22 lb (10 kg) range, the reported dose is 20-100 mcg per day, given once daily, typically for 2-4 weeks. At a representative weight of 5 kg (about 11 lb), that works out to roughly 10–50 mcg per dose. These figures are reported from the source literature and are not recommendations.
How often should a small / toy breed be given BPC-157?+
Once daily is the reported frequency, over a course of 2-4 weeks. See the cycling guide for how breaks are structured.
Is BPC-157 safe for a small / toy breed?+
BPC-157 has the most reassuring safety record of any compound on this site as it applies to dogs. A dedicated preclinical safety evaluation identified no lethal dose, no genotoxicity, and no teratogenicity, and the canine pharmacokinetic study reported good tolerance across seven days of repeated dosing at 30 mcg/kg — several times a typical clinical dose. The meaningful caveat is duration rather than dose: long-term continuous use in dogs has not been studied.
