  • RIPEX 225 is a ready-made oil blend of three anabolic steroids with a short ester: testosterone propionate, drostanolone (masteron) propionate and trenbolone acetate.
  • There is no study on the blend itself, neither in the trial registry nor in PubMed. Everything here comes from studies on the components or on anabolic steroid users in general.67
  • Short esters act fast and briefly: testosterone propionate stayed above the normal level for 48 hours after one injection. Trenbolone binds the androgen receptor about three times as strongly as testosterone, studied mainly in animals.21
  • Studies of steroid users show risks: weaker pumping function of the heart, more plaque in the coronary arteries and in some people too little of their own testosterone even years after stopping.34
  • The blend is not approved. ChEMBL lists testosterone propionate and drostanolone propionate as formerly approved, trenbolone acetate only up to phase 2. Everything here is the state of research, not a recommendation.8

What is RIPEX 225?

RIPEX 225 combines three anabolic steroids each in the short ester form: testosterone propionate, masteron propionate and trenbolone acetate (225mg/ml total). The short esters make the stack act fast but require more frequent injections. A classic cut/hardness stack.

Anabolic steroids, not peptides, ready to use.

Simplified: more compounds in one bottle does not automatically mean better. There is no study on the blend itself. 6

How it works

Like the TMT stack but in short esters: testosterone as the base, trenbolone as the potent driver, masteron for hardness. The short esters (propionate, acetate) mean fast onset but shorter duration, hence more frequent dosing.

What the research shows

The individual compounds are described (trenbolone: Yarrow, 2010; masteron as a DHT derivative). For the fixed combination there is no study. The short esters are only a release matter, not their own evidence base. Performance doses are not study-proven.

Study results

What the trials measured

Interactive: switch tabs, tap points, show or hide arms. Arms are named relative to each other, no dosing advice.

Pumping function of the heart3

Mean left ventricular ejection fraction, weight lifters aged 34 to 54

With and without steroids3 86 users with at least 2 years, 54 without
Long-term steroid users 52%
Weight lifters without steroids 63%
Users: currently on or off3 58 currently on, 28 off
Users, currently on steroids 49%
Users, currently off 58%

Cross-sectional study: shows an association, not proof. Users also had more plaque in the coronary arteries, the more the longer they had used steroids.

Testosterone below the reference limit4

Share with total testosterone below 12.1 nmol/l, former users on average 2.5 years after stopping

Recreational strength athletes4 33 former users, 30 controls
Former users 27%
Control group 0%

In the 37 current users LH and FSH were suppressed and AMH and inhibin B clearly lowered, a sign of impaired sperm production.

Research status

Where the research stands

There is no registered trial on the blend. The registry finds none on trenbolone or drostanolone either. As of 26 Oct 2026.

  1. Preclinical Trenbolone: muscle, bone and fat in animal studies
  2. Phase 1 no registered trial
  3. Phase 2 no registered trial
  4. Phase 3 no registered trial
  5. Approval not yet
The blend is not approved. ChEMBL lists testosterone propionate (from 1974) and drostanolone propionate (from 1982) as approved, both no longer on the market today. Trenbolone acetate only reached phase 2.6

So far there is no registered trial in humans.

Side effects

  • Harsh tren profile: sleep problems, night sweats, irritability, prolactin.
  • Frequent injections can irritate the sites.
  • Lipid shift, cardiovascular load, hair-loss risk (DHT part).

Tolerability

Symptoms years after stopping

Out of 100 former users, how many had the symptom, on average 2.5 years after stopping. No study on the blend.

40 of 100 Former users
Event Former users
Reduced libido4 40%
Erectile dysfunction4 27%
Depressive symptoms4 24%

These shares were higher than in current users and controls. A review names more libido, acne, more body hair and more aggression as the most common self-reported effects, plus falling HDL and rising blood pressure.45

Practice

  1. Not a beginner stack, the tren part defines the profile.

  2. Plan frequent dosing, rotate injection sites carefully.

  3. Watch bloodwork, plan a post-cycle, banned in official competition (WADA S1).

FAQ

Common questions about RIPEX 225

Short answers, each backed by the sources below.

Are there studies on RIPEX 225?

No. As of 26 October 2026 there is no study on the blend, neither on ClinicalTrials.gov nor in PubMed. No trial is registered for trenbolone or drostanolone either. The data here come from studies on single components and on steroid users in general.67

What do the short esters mean?

Propionate and acetate are short chains on the compound. They leave the oil depot quickly, the effect starts early and lasts briefly. In one study testosterone stayed above the normal level for 48 hours after an injection of testosterone propionate, the body's own testosterone barely changed. That is why it is injected more often than long esters.2

What is known about trenbolone?

According to a review trenbolone binds the androgen receptor about three times as strongly as testosterone. In animal studies it promoted muscle and bone and lowered body fat. Because it is broken down into weaker androgens, androgen-sensitive tissue like the prostate grew less. Almost all data come from animal studies, as a medicine trenbolone acetate only reached phase 2.18

What do studies show about the heart?

In a study of 140 weight lifters 86 long-term steroid users had lower pumping function (mean ejection fraction 52 versus 63 percent) and more plaque in the coronary arteries. Those currently on steroids were at 49 percent, those taking a break at 58. The longer the use, the more plaque. The study shows an association, not proof.3

Does the hormone axis recover after stopping?

Not in everyone. In a Danish study former users on average 2.5 years after stopping had less testosterone than controls, 27.2 percent were below the reference limit. They more often had depressive symptoms, erectile dysfunction and reduced libido. In current users LH and FSH were suppressed and the markers of sperm production clearly lowered.4

Which side effects do reviews name?

Athletes most often self-report more libido, acne, more body hair and more aggression. On top come falling HDL cholesterol, rising blood pressure and suppressed own hormone production that can last for months. The authors stress that studies mostly used lower amounts than in practice, so the risks are more likely underestimated.5

Is RIPEX 225 approved?

No. The blend is not a medicine. ChEMBL lists testosterone propionate and drostanolone propionate as formerly approved and no longer on the market today, trenbolone acetate only with phase 2. Everything here is the state of research, not a recommendation.8

Glossary

Terms explained briefly

Dotted words in the text open these explanations directly.

Acetate
A very short ester, for example in trenbolone acetate.
DHT
Dihydrotestosterone, a strong androgen. It acts on skin, hair and prostate, for example.
Ejection fraction
Share of blood the left ventricle pumps out per beat. A measure of pumping function.
Ester
An attached acid chain. It makes the compound oil-soluble and sets how fast it is released from the depot. It is split off in the blood.
Intramuscular
Into the muscle, for example the glute or thigh.
Masteron (drostanolone)
A DHT-derived anabolic steroid that is not converted to oestrogen.
Post-cycle
The time after stopping in which the body's own hormone production is meant to restart.
Prolactin
A pituitary hormone. A raised level can affect libido and breast tissue.
Propionate
A short ester. The compound reaches the blood quickly and is gone quickly.
Trenbolone
A synthetic 19-nor anabolic steroid that binds the androgen receptor strongly. Studied almost only in animals.
WADA
The World Anti-Doping Agency. Anabolic steroids are in category S1 there and banned in competitive sport.

Practice

PCT / after coming off

Anabolic substances suppress the body's own testosterone production in the research context. Anyone who comes off a cycle (rather than running it continuously) typically uses a post-cycle therapy (PCT) to restart the natural axis (HPTA).

The standard scheme in the research/literature context combines a SERM (tamoxifen and/or clomifene, alternatively enclomiphene) over roughly four weeks, optionally preceded by HCG to re-sensitise the testes before the SERM block. An aromatase inhibitor (anastrozole/exemestane) belongs more to on-cycle estrogen control than to the PCT itself.

19-nor note: nandrolone and trenbolone are progestagenic and can raise prolactin. The literature additionally discusses a prolactin-lowering agent (cabergoline) and a somewhat longer wash-out window here.

Tip: order the PCT items together with the cycle so they are already on hand when you come off.
