Testosterone propionate is a common oil-based injectable testosterone. The added propionate extends the activity of the testosterone but it is still comparatively much faster acting than other testosterone esters such as cypionate and enanthate.
While cypionate and enanthate are injected weekly, propionate is most commonly injected at least every third day to keep blood levels steady. For strength and muscle mass gains, this drug is quite effective.
With propionate, androgenic side effects seem somewhat less pronounced than with the other testosterones, probably due to the fact that blood levels do not build up as high. Users often report less gynecomastia trouble, lower water retention and commonly claim to be harder on prop than with the others.
This however is still a testosterone and, as with all testosterone products, androgenic side effects are unavoidable. It should also be noted that propionate is often a very painful injection. Users very regularly report swelling and noticeable pain for days after a shot.
As a short-lived oil based injectable, most will want to opt for doses of 50-100 mg every day to every other day. Those of a lighter stature seeking to use it for cutting purposes may want to make that every 2nd or 3rd day, or add proviron as a precaution instead, 50-100 mg/day sufficing in most cases.
The site of injection is best rotated each time, or problem can occur. The compound is irritative and the damage to the skin and underlying tissue can cause some cosmetic problems if it becomes repetitive. Subcutaneously, balls of fat or tissue can build up. In most cases these need to surgically removed. So rotating is wise.
For bulking purposes one is best to stack testosterone with a base compound such as Deca-Durabolin or Equipoise, and can addition Dianabol or Anadrol for 5-6 weeks, at the beginning, to kickstart the gains a bit. Most will choose for a more user-friendly, longer-acting testosterone for bulking purposes however.
For cutting, the best and primary addition is that of Proviron, which will reduce if not stop estrogen build-up, increase muscle hardness and strength and allow for a higher free testosterone level. But naturally other compounds lend themselves quite well too.
Base compounds such as Equipoise or Primobolan making a good match for longer stacks, and towards contest time steroids such as Anavar or Winstrol make the best matches, as they too will help increase muscle hardness and decrease body-fat, while maintaining lean muscle mass.
With testosterone, most any combination is possible. Because testosterone is always the stronger compound in a stack.
In terms of ancillaries, the use of anti-estrogens is advised. For cutting puposes one will want to run Proviron alongside the testosterone for the length of the stack, which will rarely make the use of other anti-estrogens a necessity.
If no Proviron or arimidex is used, you may want to keep some Nolvadex handy. Should problems arise starting on 20-40 mg of Nolvadex until a while after problems subside should be sufficient for all intents and purposes.
Testosterone, being a heavily aromatizing compound, is also quite suppressive of natural testosterone (most so, safe for nandrolone) so a post-cycle therapy with Nolva/Clomid and HCG is necessary.
Usually one will start HCG the last week or two weeks of a stack and run it about 4 weeks. HCG shots of 1500-3000 IU given every 5th or 6th day. That means during the end of a cycle, one shot of HCG is given per two shots of testosterone.
A user should also opt to wait on using clomid or Nolvadex until the androgen is cleared. For longer esters that was 1.5 to 2 weeks, obviously that time-frame should be reduced to 1 week or even half a week for propionate.
One will then start on either 40-50 mg of Nolvadex or 150 mg of Clomid per day for a period of two weeks, and then follow it up with 20-25 mg of Nolvadex or 100 mg of Clomid per day for another two weeks. Post-cycle therapy will facilitate the return of natural testosterone and make it more likely for the user to retain most of the mass he gained while on the cycle.
