How many units of the Wolverine stack?

From a 20 mg blend vial with 2 mL of water, 1 mg of blend is 10 units and holds 500 mcg of each peptide. Reports commonly describe 5 to 10 units a day.

Is the Wolverine stack better as a blend or as separate vials?

Separate vials let you run TB-500 twice weekly with a loading phase and BPC-157 daily, which is how each is usually reported. A blend locks both to the same schedule and a 1:1 ratio. The blend is simpler; the separate vials are more flexible.

How much water for a 20 mg BPC-157 TB-500 blend vial?

2 mL gives 10 mg/mL, so 1 mg of blend is 10 units and 0.5 mg is 5 units. That keeps the reported doses in the easy-to-read part of the barrel.

Wolverine stack dosing chart

BPC-157 and TB-500, as a 20 mg blend vial and as two separate vials, every common draw converted to units and split into each peptide.

The Wolverine stack is BPC-157 and TB-500 together. It comes two ways: a single blend vial, usually 10 mg of each (20 mg total), or two separate vials dosed on their own schedules. The chart covers both. Neither peptide is an approved medicine; both are sold for research.

Blend vial, 20 mg (10 mg BPC-157 + 10 mg TB-500)

Every draw is half BPC-157 and half TB-500. Commonly reported: 0.5 to 1 mg of blend per day, which is 250 to 500 mcg of each.

20 mg in 1 mL (20 mg/mL)

Draw	Total blend	BPC-157	TB-500
2.5 units	0.5 mg	250 mcg	250 mcg
5 units	1 mg	500 mcg	500 mcg
10 units	2 mg	1000 mcg	1000 mcg
15 units	3 mg	1500 mcg	1500 mcg
20 units	4 mg	2000 mcg	2000 mcg

20 mg in 2 mL (10 mg/mL)

Draw	Total blend	BPC-157	TB-500
2.5 units	0.25 mg	125 mcg	125 mcg
5 units	0.5 mg	250 mcg	250 mcg
10 units	1 mg	500 mcg	500 mcg
15 units	1.5 mg	750 mcg	750 mcg
20 units	2 mg	1000 mcg	1000 mcg

20 mg in 3 mL (6.7 mg/mL)

Draw	Total blend	BPC-157	TB-500
2.5 units	0.167 mg	83 mcg	83 mcg
5 units	0.333 mg	167 mcg	167 mcg
10 units	0.667 mg	333 mcg	333 mcg
15 units	1 mg	500 mcg	500 mcg
20 units	1.333 mg	667 mcg	667 mcg

Separate vials, dosed on their own schedules

This is how the two are usually reported when bought separately, and the schedules are not the same shape, which is the argument for separate vials.

Peptide	Vial	Water	Dose	Draw	U-100 units	Reported frequency
BPC-157	5 mg	2 mL	250 mcg	0.1 mL	10 units	daily
BPC-157	5 mg	2 mL	500 mcg	0.2 mL	20 units	daily
BPC-157	10 mg	2 mL	500 mcg	0.1 mL	10 units	daily
TB-500	5 mg	2 mL	2 mg	0.8 mL	80 units	twice weekly
TB-500	5 mg	1 mL	2.5 mg	0.5 mL	50 units	twice weekly
TB-500	10 mg	2 mL	2.5 mg	0.5 mL	50 units	twice weekly
TB-500	10 mg	2 mL	5 mg	1 mL	100 units	twice weekly

Reported protocols often run TB-500 as a loading phase (4 to 10 mg a week split in two) for four to six weeks and then drop to a maintenance dose, while BPC-157 stays at a steady daily amount. A blend vial cannot do that.

Read this before you use the numbers. This is a unit-conversion tool. It converts a vial strength and a volume of bacteriostatic water into a concentration, a draw volume and a mark on an insulin syringe. It does not tell you what to take, whether to take it, or whether a compound is safe for you. Most of the compounds listed here are sold for laboratory research use and are not approved for human use. Nothing on this site is medical advice. Dosing decisions belong with a licensed clinician who knows your history. Always confirm the strength printed on your own vial rather than trusting a preset.
