Am wondering if 10 mg tab for a 4 week cycle would help. Am doing an 8 week get back to sprinting program , want to beat provincial 100 m record!
I would go 50mg/day. 10mg for a male is a waste. Make sure you have a joint support supp as winstrol can dry your joints out.
Help what? Run faster? No.
Based on what data or study.
I have only my experiences over three decades to reference. Almost to the day, every time, on the 10th day of my AAS cycles (I always used orals - Dianabol, Winstrol, Anavar, or Anadrol 50) I felt a significant strength increase. When I was playing rugby, I felt I had a little better speed about the same timing. But that was just a feeling. Maybe I was just the same speed and it was all in my mind.

I would go 50mg/day
The way athletes use AAS is not the same as the way bodybuilders use them
That’s a huge dose for an athlete that will cause crippling pumps during practice

I felt a significant strength increase.
Yeah but running a 100m? Surely today, 3 decades later, there’s better options to take for an endurance boost? And less harmful at that.
Maybe i should say I’m not certain it would help this guy, but certainly there’s better options for him.
How much stanozolol did Ben Johnson take? It seemed to work well for him. The best salesperson Winstrol never had.

How much stanozolol did Ben Johnson take?
In the late 1980’s it was typical to take up to 20mg/day of Winstrol, but it was usually an oral addition to the AAS stack.
My college friend who was a 880 yard track runner got me started lifting weights. His doctor, who was his godfather when his father died, prescribed him WInstrol when he was in high school. He was prescribed 4mg/day. Was Winstrol a benefit for his running the 880yd race? I don’t know. What I felt using oral AAS was a perceived increase in sprint speed, not an endurance increase (though that might have also increased.)

better options to take for an endurance boost?
What causes you to connect AAS to endurance more so than sprint speed? It is common knowledge that AAS target fast twitch muscle fibers much more so than slow twitch muscle fibers.

Nothing. I’m commenting on this guy’s use of Winstrol, at a low dose, and his desire to boost his 100m time. It’s just my opinion
I appreciate your reply, I am mainly looking for some strength, and endurance boost, the speed part is on my second month pf training. The Albuterol will help as it build fast twitch fibers an has an anabolic effect, also a vert short half life, not that they would test masters race, I have astma so a trace is allowable. If you had any other suggestions they woyld be great. My Bo leds sap the get up and go like crazy!

The Albuterol will help as it build fast twitch fibers
I read a lot about the effects of Albuterol but never that it builds fast twitch muscle fibers. Do you have a link to share to verify this?
There are a few studies, this is the page I searched ,albuterol for fast twitch muscle,
https://journals.physiology.org/doi/full/10.1152/japplphysiol.00553.2020 Is one link. I still work as full time as possible( long story), but I am at a semi rural ER just outside ofEdmonton in suburb. We get out share of weird od’s and stuff , and sometimes we get stuff we shouldn’t , whether EMS brings them of the walk in. I was on when a pt came in with neck swelling, we had all the toys out to cut an airway but got in a breathing tube with just about 2 minutes to spare! I’ve been a Respiratory Therapist for over 35 yrs, so I was calm as a cucmber but the adrenaline rush lasted for hours. I have been through the wars and have seen tons of crazy shit, I was a high strung sprinter do this job was made for me. I decided to start doing push ups at night to kill time and strengthen up a bit, easier to flirt with young nurses with guns! I was taking 15 mg albuterol, and went from barely getting through 3x20, but was up to 3x50 in a week, I know thats not huge, that was our warmup 40 yrs ago, but for a 65 ye old who had not done anything in years I thought great! We have wire equipment carts, so I added band exercises in my office. Have hust started a back to sprinting orogram, lots of drills, buildng proper muscles etc before introducing speed after 8 weeks. Did my first 25mg Winny, 17 mg Albuterol, no muscle soreness today, hitting the pool for flotation belt sprints and figuring out where to start on weights. The winny is just to get a head start on strength training.
