Unanswered MK-2866 / GK-501516 stack & questions about AI and PCT


New member
Hi guys,

I’m new to all of this so please forgive me if I sound ignorant.

I’ve been training since 16, 23 now. I started taking Osterine(20mg) and Cardarine (10&10mg) per day for 2 weeks now.

I’m planning to continue for around 10 weeks.

I know I’m stupid because I didn’t do any blood tests prior to this, but I feel like im in pretty good shape.

I wanted to know if I need an AI or PCT and when to take all of this and if it’s even nessasary

Also I’m 6ft3 around 80kg

Thanks guys,

Personally I would come off, do a very mild pct, most of the experienced peds users could help you with this, then get bloods done first, you need them for when your finished with the cycle, you know what levels to aim for if anything is elevated or suppressed.
