Peptides I tried are BPC-157 TB-500, GHK-Cu, CJC Ipa and if u want to count them to it - Semax, Selank.
In case of an overuse injury, I got no benefit from BPC TB over a month of daily injections. GHK-Cu same protocol, nothing noticeable for me. CJC Ipa initially felt deeper sleep, but over the weeks my RHR increased despite low dose for me to feel too uncomfortable.
Semax and Selank I administered nasally and did nothing. Felt more from nasal BPC at first try in terms of mental recovery from stims.
I'm not saying they don't do anything, but for me the impact was just not there. Plus uncomfortable feel. Maybe I should've taken 1g of BPC and TB like is now advocated, I only used half the dose.
CJC Ipa I worked slowly up to 200mcg each, weekends off. In hopes to enhance recovery slightly. But this was the main factor for me to just stop with all of it.
My conclusion is that nutrition and sleep itself are impactful enough. After deeper research, that growth hormone releasing peptides with already good physical shape might cause more detriment to sth like blood sugar, worsening blood markers. I stopped too early before retesting my markers to see the effects. Couldn't bear doing it longer.
