does that work then for my cycle safely?
This being your first 'cycle' with a relatively mild pro-hormone. I doubt you will have any noticeable side effects. Then you'll think everyone on here was a dumbass that was trying to give you advice.
You are 18, you have testosterone pouring out of your ears right now. Your testosterone will be the highest it will ever be in your life for about the next 5 years.
Pro-hormones make your body 'think' they are getting testosterone, so they shut off your natural production.
Do yourself a favor and train natural until you are at least 25 before you consider any type of steroid. You are taking the easy way to getting quick muscle -- the amount of muscle you gain off this cycle will not be worth the side effects, and you will lose a significant amount of your gains after cycle.
Train, sleep, and eat eat eat eat eat. Steroids do not put on muscle. Food does.
Quit looking for an easy route here. You will not get any constructive advice on this forum when it comes to an 18 year olds and steroids.
Also I highly doubt that bottle says 18 rather than 21
DO NOT TAKE THE PRO-HORMONE. RETURN THE STACK
If you want advice on natural training or non-hormonal supplements message me. My avatar is a year old and I'm still natural.
