Propionate 100 by Zyvex Pharmaceuticals
What Is Propionate 100?
Propionate 100 from Zyvex Pharmaceuticals is testosterone propionate at 100 mg per ml in a 10 ml vial. The propionate ester is short, which makes this testosterone fast to act and fast to clear - a favorite for short cycles, cutting phases and quick adjustments.
Because the ester clears in a couple of days, injections run every other day to keep levels even. That rhythm is the trade-off for a compound that lets users end the cycle sooner, start PCT sooner and control estrogen swings more tightly than with long esters.
Propionate 100 Dosage
Testosterone propionate needs frequent small injections thanks to its short half-life of about 19 hours.
| Protocol | Weekly Dose | Schedule |
|---|---|---|
| Cutting cycle base | 350 mg | EOD injections |
| Standard run | 400-500 mg | EOD Common |
| Advanced | 500-700 mg | Daily or EOD |
A 10 ml vial at 100 mg/ml holds 1000 mg - about two weeks at 500 mg weekly. Estrogen control follows the same rules as any testosterone.

Why choose propionate over cypionate or enanthate?
Propionate suits short cycles, quick adjustments and users who want the compound out of their system fast. The trade-off is frequent injections.
What is the right Propionate 100 dosage?
A standard run uses 350-500 mg per week injected EOD, which at 100 mg/ml means about 0.5-0.7 ml per shot.
How long does Propionate 100 take to work?
Short esters saturate in about two weeks, so effects appear faster than with long-ester testosterone.
Is propionate more painful to inject?
Some users report sharper post-injection soreness with propionate than with longer esters. Slow injection and site rotation help.
Do you need an AI with propionate?
Yes - propionate aromatizes like any testosterone, so keep Arimidex or Aromasin on hand and dose by estradiol bloodwork.
Do you need PCT after propionate?
Yes, and it can start sooner than with long esters because the compound clears within days. A SERM-based PCT follows the cycle.
